[PHP] iphone php
An appl that has been working fine for a year now and fine up through last week, suddenly is not working on my iphone. The only differences between using it on a pc, ipad or iphone are for font sizes and such (handled by JS) so I'm puzzled as to what is going on. I do the same exact thing on each of these 3 devices and the iphone fails. The specifics are : I'm entering a date into an input field and php is supposed to retrieve it and display a record that is retrieved using that input. The iphone for some reason is not getting my input (passed via POST) correctly, yet it's the same script being run for each device. Trying not to paranoid, but does anyone think that Apple could have done something to my iphone in the last few days? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Have you debugged the code to see what your script is receiving from Safari? If not then I respectfully refer you to the advice you recently gave Jay. -Stuart Actually, I have been working on it for about 4 hours now. Very simple script (like all of mine) that is working rock solid on 2 out of 3 boxes. In the last few mins I re-booted my phone and it is now doing something even worse! As I fill in the date field using the iphone, the chars are showing up in the field onscreen. But - once I close the keyboard (not submit) - the input field reverts to ONLY one character! This also happens if I hit the Next button on the keyboard to advance to the next input field. And it is that character that my php script then receives when I do submit the form. I have no code anywhere that addresses the input fields with JS so it's not something that I have 'forgotten' about - it is totally new and strange behavior.

[PHP] Re: iphone php
Solution! Found this post from last Fall. Didn't experience the problem because my appl is a NASCAR one and the season ended before this problem was created, apparently by an Apple update on my phone. Here's a link to the story: https://discussions.apple.com/thread/3408352?tstart=0 To summarize - apparently ios 5.0 changed how the number attribute works on an input tag. Now it sees any input using that feature as a purely numeric field which in my case causes my date entry to be truncated once the first slash was hit. Now that I'm using my appl with the start of the new season, I'm running into it.

When I return that dataset in this case I return seven columns of data with the parent being in the leftmost column and descending to the right. The goal with the the recursive function was to get each descendant line so that it could be formatted in a nested unordered list. So in the SQL below you get 9 records. For each of the 9 records you could get any number of children depending on which of the 9 you're looking at. Then for each of those children you could get their descendants and so on. I was doing it the long way at first, until a recursive function was suggested. The problem that I was having there was formatting the ul's and li's properly. I'm not saying you should get rid of the recursive function calls, but rather, why not pull all your data in one SQL call, then use recursive functions on the returned array of data. It will save a little time by not hitting the DB on each function call too. Now I feel as if I am really close to a better solution than the brute force method.

[PHP] SESSION var and Objects problem
My first foray into classes objects.
When retrieving a set of records, I'm using a class to build an object. At
this time I save each record/object into a Session array by doing this:
$rows = mysql_num_rows($qrslts);
if ($rows 0)
for ($i=1;$i=$rows;$i++)
{
$row = mysql_fetch_array($qrslts);
$e = new Entry;
if ($e-GetAnEntry($row['recordkey'],$row['Eventcode']))
{
$evts[] = $e;
array_push($_SESSION['TMScurr_evts'],$e); // THIS DOESN'T
$cls_errs .= Stored $e-event in sess var $i-1; ; // THIS
WORKS
}
else
$cls_errs .= Could not retrieve event record for
.$row['recordkey']. .$row['Eventcode'];
}
The above code works AFAIK - the line above the array_push correctly stores
my retreived record data in the $evts array just fine and I can see the
data when I use that array to display my page.
Note also that the var $cls_errs following the array_push does show me that
valid values are being stored in $e
Later on, in my main process I attempt to retreive the contents of my
Session var to use to re-display the data. The code for that doesn't
display any values. In trying to debug this here is what I've done:
$cnt = count($_SESSION['TMScurr_evts']);
echo In Display process with $cnt recs in session var TMScurr_evts. ;
// THIS WORKS
reset($_SESSION['TMScurr_evts']);
$e = new Entry;
for ($i=0;$icount($_SESSION['TMScurr_evts']);$i++)
{
$e = array_pop($_SESSION['TMScurr_evts']);
echo in Display process - sess event $i is $e-eventbr;//
THIS DOESN'T
}
This debugging code correctly tells me how many entries are in the Session
array variable, but the attempt to echo the values stored in the first field
of each object contained in it shows blank for each one.
What am I doing wrong when I try to pull the contents of my session array
out and store them back into an Entry object, one at a time, so that I can
display the object on my webpage??

Re: [PHP] SESSION var and Objects problem
ok - In examinig the objects in the Session after the data has been displayed and the user has hit triggered a re-entry into my script (just one script involved here), the objects in the session array now say [__PHP_Incomplete_Class_Name and __PHP_Incomplete_Class Object . They didn't say that during my examiniation of the sess var before exiting the script. Also with All error reporting on (a great tip that I never think of) I get many messages indicating that the object may not have been loaded. I don't know what this means. The include file for my class is present in my script and is always loaded. But at this point in the process no functions of the class have been called. Is that a problem? In trying to re-display my data stored in the Sessioin array I instantiate a var of the class and then pop an array off the session var and assign it to the object and then call my display function to show the data on the webpage - that is where I get the errors. Here is one of these messages: Notice: DisplayAnEntry() [function.displayanentry]: The script tried to execute a method or access a property of an incomplete object.

It does produce the right query for only the first child in each case, I cannot
get it to go deeper. I have just been looking at it for too long. TVMIA!
Forgot to say that if I isolate any one level without recursion I get all of

How are you calling this? What are your initial arguments?

[PHP] Re: Long Live GOTO
NO GO! As one who started back in the 70's with old style coding that utilized GoTo in Cobol, Fortran, etc. and had to deal with spaghetti code written by even earlier developers who never considered that someone else would have to maintain their code, I feel strongly that GoTo is not to be used. There are many ways of avoiding the perceived need for a GoTo statement. The 'Break' is one in PHP as is the 'Continue'. Better instruction in programming since the 70's has taught beginning coders the value of well-structured code using function calls and distinct paragraphs (if you will) of code that help to structure the entire process into manageable chunks to facilitate understanding and maintenance. Random GoTos interspersed into code because a designer just hasn't taken the time to write it well is just not smart. Think of a well-written article in a journal or newspaper. Do you think that the author just threw it together and the points to be made just fell out of it? No - that writer probably spent a good amount of time re-working his first draft into second and third drafts before getting his thoughts and words in the right order to facilitate the presentation of the ideas he was trying to communicate. The same process can and should be brought into play when writing code and in that way produce a quality product that will stand the test of time and lend itself easily to necessary improvements when needed.

I've not used a goto since I stopped writing in FORTRAN in 1978, and not missed it [1]. Neither do I ever have deeply nested if-then-else - these are a good source of bugs. I suppose the rest of your article might have been dealing with simplifying val_nested() but TBH I wasn't interested enough to find out. [1] Not quite true - a Pascal compiler I once had to use in 1983 lacked a return statement, so I had to fake it by putting a 999: label at the end of the function and goto-ing to that. Goto has it's uses, demonizing it due to the poor implementation and misuse of it's same-named historical counterparts is an exercise in closed-mindedness. Goto can really shine in parsers and various other scenarios. While the example shown may be contrived it doesn't miss the point. Since goto cannot jump out of the function nor jump into the function it is well constrained to provide readability while eliminating complexity. Additionally, it is quite likely that it is more optimal. A single jump target versus one or more state variables to control nested conditionals or loops results in faster execution (also important for parsers). I've had a strong opinion on goto for a very long time. I was one of the proponents who argued on internals for its inclusion several years ago. I stand by its utility and refer the reader to the fact that many open source projects, especially ones that use some kind of parser, have goto hidden within their implementation. You can find it in the C code for the PHP, MySQL, and Apache to name a few easily recognizable projects. Cheers, Rob. All excellent points, Robert. Tim mentioned that my example was a straw-man, and you mentioned it was contrived. Actually, it's a refactoring of a real function in my web framework that I've committed to trunk and going to use for a while (it's functionally inspired, and having the ability to store and retrieve immutable values is quite handy in this situation.) I like experimenting with different approaches (my background is in cognitive psychology), and there's certainly research to show that deeply nested ifs are problematic, cognitively speaking. Then, there are the other techniques mentioned in the blog post to deal with them (guard clauses, pulling out functions, grouping conditions), but they have they're issues, too, in terms of processing (they can hurt proximity of related concepts, forcing programmers to work against the mental model they've built up of a problem, etc.) There are going to be issues with the goto approach I took to refactoring the function, too, but I'm keenly interested in playing around with it a while and letting the evidence accrue over time. I've read many, many sources that seem to reject ANY approach using GOTO even without properly evaluating its use within a language like PHP that offers some beneficial restrictions. Thanks for the insights (and I'm glad you pushed for the construct :) Adam -- Nephtali: A simple, flexible, fast, and security-focused PHP framework http://nephtaliproject.com The use of goto was acceptable in the early days of computer programming. It was a major part of it in fact. I believe that the trend to remove them from usage was because of that very thing. The early programs naturally had to go thru improvements maintenance but a new generation of programmers came along and that was when the problem with GoTos was realized. It was difficult if not impossible to follow a process completely through so that one could implement a change easily and in the end people unfamiliar with the entire program were forced to put code into multiple spots to ensure that the change they were trying to implement got hit in all the correct circumstances. Gotos allow for too much flexibility and open up diverging paths in the flow of the process. Sure - it works for the original developer, but code must be seen as not the work of one author but as a product that can later be modified/improved/corrected by future authors. Sure - you can say that the life of a specific program/module may not be that long in today's fast-paced changing technologies, but the same argument

They have been added in PHP 4.0.4. 2) No external libraries are needed to build this extension. 3) This » PECL extension is not bundled with PHP.

Well, by the sounds of it, you are using a join to combine the two tables into
one result set and you have doubling up on the parent information.
I would do it like this.
$SQL = 'SELECT p_id, month_name, prod_id, l_id, descr';
$results = query($SQL);
while ( $r = fetch_assoc($results) ) {
$data[$r['p_id']]['descr'] = $r['month_name'];
$data[$r['p_id']]['x'][$r['prod_id']]['descr'] = $r['descr'];
$data[$r['p_id']]['x'][$r['prod_id']]['x'][$r['l_id']] = $r;
}
print_r($data);
Now, use instead of looping through the result set multiple times, us the
$dataSet array to loop through it once.
foreach ( $data AS $months ) {
echo {$months['month']}\n;
foreach ( $months['x'] AS $prod_id = $products ) {
echo --- {$products['descr']} #{$prod_id}\n\n;
foreach ( $products['x'] AS $product ) {
echo str_pad($product['l_id'], 16, ' ', STR_PAD_LEFT), ' ',
str_pad($product['descr'], 32, ' ', STR_PAD_RIGHT), PHP_EOL;
}
echo PHP_EOL;
}
echo PHP_EOL;
}
YMMV - This is completely untested, It should give you an idea about how to
prepare/store the data and then display it.

That's a cool idea. In this case they want it on a longer single page so they
may save or print all at once.
A while back - I remember doing a query for let's say just the unique product

records with that product name and did a 2nd loop in a second table to
show them It ended up working like I wanted but I'm not sure if this was
the best way to do it

for the above to work right, you will need to loop through the mysql result set
one time. Placing all the results in to one large array. Then you can loop

What you will probably find is that you can sort all the data into the proper

Just to throw in yet another possibility:

HTML;
I love HEREDOC for slabs of HTML, sometimes SQL, email bodies, etc.
because they allow you to drop your variables into the output text
without crufting up the formatting with string concatenation, AND they
allow you to use double quotes which can be important for HTML
attributes that may contain single quotes.
So whilst either above option is fine for the specific context, I prefer
HEREDOC when there's attributes like href.
But what is preferred is rather dependent on the preferrer.
I second this example, with one minor change, I would add '{' and '}' around
variables.
echo HTML
a style=text-align:left;size:14;font-weight:bold
href=/mypage.php/{$page_id}{$page_name}/abr
HTML;
This works for $variables, $objects, and variable functions calls. But doesn't
work if you try to call functions directly (bummer).
$ cat variable_usage.php
?php
$v1 = 'Variable 1';
$o1 = new stdClass();
$o1-v1 = 'Object 1';
function something($str) {
return ...{$str}...;
}
$f1 = something;
echo _
{$v1}
{$o1-v1}
{$f1('Function 1')}
{something('F1')}
_;
?
Results in this
$ php -f variable_usage.php
Variable 1
Object 1
...Function 1...
{something('F1')}
This is why I like heredoc syntax over pretty much everything else.

Marc,
If that is the case, can you explain to us how you got the two entries in the
array to begin with? If this is from a DB query, then it should probably be
address else where. If it was loaded from a text file, it should be handled
differently.
No matter how it was created, you could always build a method (if the dataset
isn't too large) that would filter things out.
Given your example array, I would do something like this:
?php
$oldDataSet = array(
array(
contact_id = 356,
contact_first_name = Marc,
),
array(
contact_id = 247,
contact_first_name = Marc,
),
array(
contact_id = 356,
contact_first_name = Marc,
),
);
$newDataSet = array();
foreach ( $oldDataSet AS $k = $entry ) {
$newDataSet[$entry['contact_id']] = $entry;
unset($oldDataSet[$k]);
}
print_r($newDataSet);
?
This would result in something like this:
Array
(
[356] = Array
(
[contact_id] = 356
[contact_first_name] = Marc
)
[247] = Array
(
[contact_id] = 247
[contact_first_name] = Marc
)
)
Give it a try, should do what you are wanting.

Re: [PHP] Common way to store db-password of open session?
To put it another way - your appl should control the access that a user has - different screens/functions available depending upon the signon credentials. The entire application's sql use (or all 'users' of the database) should have a minimal number of user ids associated with it - both to make programming simpler and to minimize the number of 'entry' points to your database. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Nope, AFAIK everything inside the function will disappear when the function
exits. Unless you run into one of the memory release issues talked about in the
past, in that case you might be SOL.

As far as I get it, a common login strategy is to let the user login by namepassword, check it, store a login=TRUE as php-session variable and later use a common dbuser+pw to query data provided login is TRUE. This way one wouldn't have to store the users pw or actually the user wouldn't have a real db-account but rather an application account. Is this really better or equal than using real db-accounts? Should I rather store the db-credentials in a session or cookies? Session is vulnerable as any host-user could look into /tmp. This would generally be a trusted few though. On the other hand cookies could be manipulated by the user or at least be spied upon on the way between user and web-host every time the credentials are needed for a query. What exactly do you mean by db-account? I didn't understand your question, but this is what I do in my applications- When the user submits the login form, validate POST data (for mischievous stuff) and check if username password query works out successfully. If it does, store a session variable login=true and let the user work on the private parts of the site. The cookie essentially, contains just the session id. I never use cookies to store data, only sessions. I also add ip and user-agent filtering to my auth systems. Sounds like $_SESSION buffer is what you need. I use the buffer extensively in most of my designs. It seems to me that the OP isn't asking where to store it, s/he is asking what to store. I would suggest storing only the SESSION ID in the cookies. In most setups, this is done automatically. Then in the sessions file place only the information that will allow you to identify the individual in question. In some cases, I have seen were the first step is followed above, but then rather the just the identifiable information in the session, one would grab all the account details and place this information in the session instead. The only benefit I see here is the within future page requests, you don't have to hit the DB for the account details, they are in a session file that you already had to load into memory. The drawback to this approach is that all the account details are in a file on the file system that could (in some situations) be read by other system user accounts.

On 11/10/2011 6:45 AM, Bastien Koert wrote:
Morning all,
I've been having some fun with converting a text data file import into
a json object for storage.
I have a text file that is pipe delimited coming in via an upload. The
first row is the headers and the second row is the data.
Using this code:
$data = file(inline_Nov_8_2011.txt);
if(count($data)==2){
$keys = explode(|, $data[0]);
$fields = explode(|, $data[1]);
$combine = array_combine($keys, $fields);
$json = json_encode($combine);
}
After the combine, I get an array that looks like this
Array
(
['Legal Last Name '] = Andros
['Legal Middle Initial '] =
['Legal First Name '] = Marisa
['Maiden/Other Name '] =
['Social Insurance No. '] = 123456789
['Date of Birth '] = 2/1/1988
['Gender '] = Female
)
But the json encoded value looks like this (there are way more
elements but this should be enough to represent what I need to do).
{null:Andros,null:,null:Marisa,null:,null:123456789,null:2\/1\/1988,null:Female}
I have been googling for info about allowed values for the json keys,
but can't seem to find a clear doc on what is allowed and what isn't.
I have tried unquoted keys, replaced the spaced with underscores but
nothing I do seems to help.
When I echo out the json encoded data, the keys are all nulls.
Can someone point me in the correct direction? It may be that I need
to manually create the key names as an array first, which I was hoping
to avoid since the file format coming from the client is still in some
flux.
Looking at your input array example, I see that you have trailing spaces in your
keys. Looking at the working example of DiRaven, the only difference that I see
with his example is that the input key values do not have a trailing spaces.
json is probably having an issue with that trailing spaces.

Try unsetting the $row variable, you may be fetching extremely
large rows but that's a big if, because your script is allowed to
allocate 128MB of memory before puking. Are you dealing with very
large data sets from the database? If you are dealing with large
data sets, then try redefining your query.
James:
Thanks for taking time to help.
The row size is small by my standards (see below). The query result
has just under 300,000 records, and it's puking about 90% of the way
through.
Changing the while loop to:
while ($row = mysql_fetch_assoc( $result )) {
$n++;
echo sprintf( %7d %12d\n, $n, memory_get_peak_usage() );
} // while
the tail end of the output becomes:
274695134203084
274696134203524
274697134203964
PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to

Changing the while loop further to:
while ($row = mysql_fetch_assoc( $result )) {
unset( $row );
$n++;
echo sprintf( %7d %12d\n, $n, memory_get_peak_usage() );
} // while

If you are certain that your array is consecutively indexed from

$allFiles = array(coffee.jpg, tea.jpg, milk.jpg);
foreach ($allFiles as $key = $currFile) {
doThisWith($currFile);

One of the key concepts of troubleshooting is that when you encounter a problem, you try to state the problem with as simple a test case as possible, so that testing will not be complicated by extraneous variables or code that may or may not have any impact on the problem. I don't want to just count the records, I want to get some work done for a client. That work involves processing every record in the result set. Counting is just a simple process to conduct for the purpose of debugging this loop algorithm. The problem is that this algorithm fails to process all the records in the result set. I appreciate any insights you have as to why that is happening. Jim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I was glad to learn what comments were.
Eric: Please forgive me if I was curt in my message to you. I
don't mean to bite the hands that are trying to help. As Daniel
rightly observed, my concern is just that if a pretty much empty
while loop runs out of memory when trying to step through each
record, I'm really going to be hosed if I try to start doing some
productive work within the while loop.
Daniel's memory trend analysis is helpful. I'm testing from the
command line, so there's no Apache overhead, but the memory usage
starts as:
1 12145496
2 12145976
3 12146408
4 12146804
5 12147200
6 12147596
...
I normally prefer to work in PostgreSQL, but the client has already
gone down the MySQL road. Just for edification's sake, I exported
the table in PostgreSQL and re-worked my code:
if (!($db_conn = pg_connect( host=$db_host user=$db_user dbname=$db_name
password=$db_pwd )))
die( Can't connect to SQL server\n );
$qry = select * from test_table order by contract;
if ($result = pg_query( $db_conn, $qry )) {
$n = 0;
while ($row = pg_fetch_assoc( $result )) {
unset( $row );
$n++;
echo sprintf( %7d %12d\n, $n, memory_get_peak_usage() );
} // while
pg_free_result($result);
echo $n\n;
} else {
die( pg_last_error() . \n );
}
Using PostgreSQL (on a completely different machine), this runs
to completion, and memory consumption is nearly flat:
1 329412
2 329724
3 329796
4 329796
5 329796
...
295283 329860
295284 329860
295285 329860
295286 329860
295287 329860
295287
If one were to describe the memory consumption as a 'leak', then
PostgreSQL is leaking at a much slower rate than MySQL. Postgres
leaks as much over the entire run (329860-329412=448) as MySQL
does on each row. Put another way, the MySQL version leaks
memory almost 300,000 times faster.
My PostgreSQL machine also has MySQL installed, so I ran the
MySQL version of the code on that machine for testing, a second
opinion if you like. It leaked memory almost as bad as my
client's PHP/MySQL installation, but a little more slowly, 396
bytes or so per row. The slower memory consumption enabled the
code to run to completion, barely:
1 12149492
2 12149972
3 12150404
4 12150800
...
295284129087704
295285129088100
295286129088496
295287129088892
295287
So is this just a difference in the programming quality of the
database extensions for MySQL vs. PostgreSQL that one gobbles up
memory profusely, while the other one has only a slight, slow
leak?
I will try experimenting with Daniel's idea of unbuffered
queries, but my understanding is that while an unbuffered result
resource is in use, no other SQL transactions can be conducted.
Maybe I can get around that by using one MySQL connection for the
unbuffered query, and another separate MySQL connection for the
incidental SQL queries that I need to perform as I process each
record from the large dataset.

Please don't hijack other's threads to ask a question. I've
started this as a new thread to address this question.
mysql_fetch_array() grabs all of the data and places it in a
simple numerically-keyed array.
By contrast, mysql_fetch_assoc() grabs it and populates an
associative array. This means that the column names (or aliases, et
cetera) become the keys for the array. With mysql_fetch_assoc(), you
can still call an array key by number, but it's not vice-versa with
mysql_fetch_array().
I'm not seeing any numeric keys in my mysql_fetch_assoc() arrays.
However, mysql_fetch_row (by default) does both: the array will be
indexed numerically from 0 to N-1 corresponding to the table's N
columns, and the array will also have string key indices which
correspond to the query's column names. So by default,
mysql_fetch_row uses twice the amount of data, because each field
appears in the array twice.
var_dump( $row ) will show in graphic detail.

Yes it is just phone numbers... The only select that I'm running on the
entire site is related to the pagination... A simple:
$sqlCount = SELECT COUNT(*) FROM main WHERE state = '{$state}';
which limits it to everything inside the state... Unfortunately if you look
at the possibilities, it's still quite a large dataset... 89 million :)
The rest of the query's will be much more limited to areacode, exchange, and
in some cases the full phone number... Maybe the better way to do it would be
not to count the records But set a variable with the total count... That
way I don't have to load all the data... The data amount won't change alot...
Easy enough to set a variable... Just need to see if I can integrate that
with the pagination...
Back to the drawing board! :)

It turns out the issue was actually in the pagination... I'm reworking the
whole thing and stream lining it... But in the pagination that I found on
the internet it used a SELECT COUNT(*) WHERE state='{$state}'; and the
COUNT was killing the time... Once that was removed, I was displaying
records faster then I could imagine... So it's off to pagination land to fix
it! And possibly redo the entire thing!
So you're still going to generate pages and pages of an un-manageable volume
of data?
Sorry, but I offer my congratulations on producing a technically marvelous

Re: [PHP] Exporting large data from mysql to html using php
Yes - but - we're talking about a user-app that the OP is trying to provide 89M records to. Sure - some users might have need of looking at even as much as a million records IF they were researching something that needed it. But - for the 'general' user of an app - I cannot see a need to be providing even that much data. Think about it - you give the user 1M records, how long is that user going to page thru the results? Let's say there are 20 results on a page and it takes a mere (wow!) 2 seconds to scan thru them looking for something apparently very obvious. That's 600 results viewed per minute at best. Six hundred into a M is 1666 minutes which is 27+ hours. Even at 1 second per page view time, it's still more time than in a normal work day. And you want come up with a way to feed him 89M? The problem needs to be looked at differently - put together a business-smart solution to finding the needle in this haystack of 89M pieces of straw and only then apply technology to it. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thank you world !
You have two ways of solving this issue:
1) Do it in Mysql with a GROUP BY option
$results = mysql_query(SELECT model FROM table GROUP BY model)
2) Within PHP, do something like this.
$results = mysql_query(SELECT model FROM table)
# This assumes none of the values stored in DB column model are type=NULL
$model = null;
while( $row = mysql_fetch_array($results) ) {
if ( is_null($model) || $model !== $row['model'] ) {
$model = $row['model'];
echo $model . 'br /';
}
...
}
Either one should give you the same results.
