Re: [PHP] Re: What's faster using if else or arrays?
Arrays - using a silly construct that probably still takes as much time to evaluate machine-wise as anything else. And as far as readability goes, it is even sillier. IMO.

[PHP] Re: What's faster using if else or arrays?
how many entries are you talking about, ie., how many conditions? Obviously if you have more than 4-5 it's going to be easier to code up as a case statement (?) rather than an if/else.

Re: [PHP] refreshing pages in the cache

[PHP] refreshing pages in the cache
I"m trying to make my webpages display random photos on a border. Got it all working now but have a question about the IE cache. Seems that once the page has been displayed, no amount of "refresh" will make the page "rebuild" and thus show 'different' pics the second time around. Can php do something about a page in the cache? I know that the cache is there to speed up performance and all, but I thought this random image thing would work if they just hit F5 to see a new array of images.

I have managed to build include files and store them above my public folder and the called pages manage to find them from the public folder and properly include them.

Can one create a set of $_POST vars within a script or is that not do-able?

[PHP] Last Name extraction in query
having a problem posting this message - forgive any duplication please.
Hi,
I'm trying to use sql to extract the last name from a person's name field in
my table. Here's my Select:
$q = "SELECT race_winner,count(race_date) as wins,
substr(race_winner,FIELD(' ',race_winner)) as last_name
etc.,,,
My result keeps coming up with a 0 for the FIELD portion I assume
since my output shows a blank last_name. From the docs I believe it should
be giving me the right-most portion of the 'race_winner' field beginning
where the first space char is found.
Am I not using this correctly? Is there a better way to do this? I'm
trying to have my results sorted by last name and since the table was not
built with separate first/last name fields, I'm stuck with figuring
somethign out.

The output you've posted, that's rendered output, right? What's the raw
output?
By the way, the code snippet you gave us is not complete. Is there anything
else? As Dan noticed earlier, judging from that code snippet only, there
must be something else funky going on.

while(False !== ($row = mysql_fetch_array($qrslt)){
}
just so that if I have a query with 1 cell which is 0, or '', I don't
abort the loop.

[PHP] Re: echo?
By george - I think you've solved it!
As for my coding choice - that's the beauty of programming - everybody has a
way of solving a problem/creating a solution. Unless you are concerned with
performance(which in this particular case is not a concern), there is no
'wrong way'.

Yes - it is J and I. I tried using $i+1 in the echo originally but it
wouldn't run. That's why I created $j.
And just what is wrong with the old cr/lf sequence? How would you have done
it?

[PHP] echo?
Kinda new to this, but I've been puttering/writing for about 3 weeks now and have some good working screens up. Ran into something new while I was debuggina script today. Tried to echo the $i value within a for loop as part of the list of items I was building Something like for ($i=0;$i<$rows;$i++) echo $i.' '.$row['itemname']; I expected to see : 1 item1 2 item2 ... ... but instead I got 1 item1 f item2 Yes - an 'f' and not a 2. Tried it some more with this: for ($i=1;$i<10;$i++) echo $i." item".''; and got c item d item e item f item g item and so on. It seems that I can only output the value of $i if I output a string in front of it echo ' '.$i; works fine but echo $i; does not.

Or you can do the long and more memory intense way.

Your example would be good if the OP wanted checkbox'es. But with radio
buttons, the whole point (most of the time) is to have the form only allow you
to have one of the radio input fields selected at any given time. How you
showed it, it would not see the uniqueness of the radio button names, and
therefor allow more than one of the radio input fields to be selected at a time.
I would try something like this:
As long as this is correct:
Zero
One
Then I would do the following:
foreach ($_POST as $k => $v) {
if ( strpos(trim($k), 'radio_') === 0 ) {
echo $k.' is a match, and it\'s value is '.$v.'.'.PHP_EOL;
}
}

Here is an example that is in the PHP manual
http://us.php.net/manual/en/function.xml-parser-create.php#38739
The only modification that you will probably have to make is to set the
following in your php.ini file.
allow_url_include = On
and/or
allow_url_fopen = On
This would allow fopen to open the external URL and grab the data returned.

if you read the following page description of the function, you will see that
the function returns a bool value. Not the return statement of your custom
function call.
http://us.php.net/array_walk_recursive
If you read the Note under the funcname section, you will see that when you call
the function, it will pass the value as a reference, so, change around your
function like this.
$karamohOutput['test'] = "";
# notice this .>|
function test_print(&$item, $key)
{
$item = "$key holds $item\n";
}
array_walk_recursive($karamohArray, 'test_print');
print_r($karamohArray);
Give this a try and let us know.

If you would allow me to show you a little easier way of doing this.
if ( !isset($_POST['submit']) ) {
echo '';
if ($Recordset1) {
echo <<
State County
HEADER;
while ( $row = mysql_fetch_array($Recordset1) ) {
echo <<
{$row['state_id']}
{$row['name']}
ROW;
}//end while
echo '';
} else {
echo 'Error performing query: '.mysql_error().'';
}
echo '';
}
Now, the main thing I want you to see is the line for the country checkbox'es
The county[] turns the submitted values into an array. So, in the processing
script, you would do this.
$name )
echo "{$id} {$name}\n";
...
?>
Hope this clears things up for you a little.
Enjoy.

Re: [PHP] Simplifying MySql queries
On 2/12/2011 12:40 PM, Andre Polykanine wrote:
Hi all,
I'm using in my PHP script the following four MySql queries:
$q1=mysql_query("SELECT *FROM`CandidateQuestions`WHERE
`Category`='1' ORDER BY RAND() LIMIT 1");
$q2=mysql_query("SELECT *FROM`CandidateQuestions`WHERE
`Category`='2' ORDER BY RAND() LIMIT 1");
$q3=mysql_query("SELECT *FROM`CandidateQuestions`WHERE
`Category`='3' ORDER BY RAND() LIMIT 1");
$q4=mysql_query("SELECT *FROM`CandidateQuestions`WHERE
`Category`='4' ORDER BY RAND() LIMIT 1");
and here goes the question: is there a way to make these four in one
so strictly one random question is selected from all of the four
categories?
Thanks!
I think you will need something like this:
SELECT *
FROM`CandidateQuestions`
WHERE `Category` IN (1,2,3,4)
GROUP BY `Category`
ORDER BY RAND()
LIMIT 4
Now, what I'm not sure about, nor have I tested, is will mysql do the
ORDER BY RAND() before or after the GROUP BY.
If that doesn't work, then I would try this instead:
SELECT DISTINCT `Category`,
FROM`CandidateQuestions`
WHERE `Category` IN (1,2,3,4)
ORDER BY RAND()
LIMIT 4
This will probably do the distinct after the ORDER BY RAND(), but again,
completely untested. YMMV
Give them a whirl and let us know how it works out.

You cannot "override" a function. You will have to write a new function,
"my_mail" or some such. Have it take the same arguments as the built in mail
function, but internally it uses phpmailer or the likes. Then, do a search and
replace for " mail(" with " my_mail("
One other possible option, which I had not contemplated until now, would be to
actually specify a replacement sendmail executable when setting up the sendmail
option in the php.ini. You could specify a php script that can run as though it
was sendmail, accept the same arguments, etc... but do all the phpmailer stuff
inside.

Well, depends, are you running this in a browser or at the console?
If you are displaying this in a browser, you are probably seeing that
browsers do not like \n (newlines)
If in a browser, you could:
1) Wrap your output in a HTML tag
2) Use PHP's nl2br() to replace all newlines with "" tags
3) Use PHP's header() function to tell the browser to display the output
as plaintext. i.e. header('Content-Type: text/plain'); [1,2]
1 - Google "php header plain text"
2 - http://www.php.net/manual/en/function.header.php#92620
If in cli... well, you wouldn't be having this problem... :)

So, in php, I want a program to handle sending out a mail list. All this
is going to do is be a filter to exclude non subscribers, and send a

php instead.
If the submission does not come from a member, the script simply aborts.
So the script should read the subscriber file, and if the source From:
does not appear there, DIE. If it is there, walk the array and send a
copy there, then end.
Now how to do this in php? Is there an off the shelf solution?
Is this something that you plan on executing with your SMTP server or
through a web script?
Do you care how the subscribers file is managed? If at all...
How is the subscriber file formatted?
With the above questions unanswered, I would do something along the
lines of the following.
form.php:
INPUT:fromname:value (display name)
INPUT:fromaddr:value (email address)
INPUT:subject:Something special
INPUT:message:the message goes here
process.php:
IsSMTP(); // set mailer to use SMTP
$mail->Host = "mail.example.com"; // specify mail server host name
$mail->SMTPAuth = true; // turn on SMTP authentication
$mail->Username = ""; // SMTP username
$mail->Password = ""; // SMTP password
$mail->From = $clean_post['fromaddr'];
if ( !empty($clean_post['fromname']) )
{
$mail->FromName = $clean_post['fromname'];
$mail->AddReplyTo($clean_post['fromaddr'], $clean_post['fromname']);
} else {
$mail->AddReplyTo($clean_post['fromaddr']);
}
$mail->Subject = $clean_post['subject'];
$mail->Body= $clean_post['message'];
$mail->AltBody = strip_tags($clean_post['message']);
# add each person
foreach ( $subscribers AS $addr )
{
$mail->AddAddress($addr);
# if you have a name associated to that address, do this instead
# assuming line format as: em...@address.com,My Name
list($addr, $name) = explode(',', $addr, 2)
$mail->AddAddress($addr, $name);
}
if(!$mail->Send())
{
echo "Message could not be sent. ";
echo "Mailer Error: " . $mail->ErrorInfo;
exit;
}

Richard,
Looks like you need to read up on the modifiers for preg_* functions. Start
here: http://us3.php.net/manual/en/reference.pcre.pattern.modifiers.php
I would change your "second line" regex to the following.
$content = preg_replace("//is", "", $content);
The modifiers after the second / are
i = case-insensitive
s = include new lines in your '.' character match.
New lines are excluded by default.
Can't remember right now, nor do I have the time to test, you might need to
invert the greediness of the match using a 'U' after the second / also.
So...
$content = preg_replace("//isU", "", $content);
YMMV
Let us know how this works out for you.

If this isn't it, I think you should explain (in sudo code) exactly the steps
you are expecting things to.
Example sudo code
1. display form 'A'
2. Person enters dob and presses submit
3. processing script stores dob submitted
4. display form 'B'
5. person enters name of kitten and presses submit
6. processing script retrieves dob previously stored
7. calculate age
8. display age
...
10. What happen to the kitten???
Form 'A':
Enter your date of birth, in mm/dd/ format:
Form 'B':
Enter your kitten's name:
Anyways, that is the idea.
Let us know.

The code below displays both forms simultaneously. After the data is

This is completely untested, typed directly in the email client. Most
of the code is cut/paste from your examples. But, it should give you a
good starting point for a multi-step form type.

Actually...
Specified here [1] it says that the {1,} is the same as '+'. I think you should
drop the comma. If you don't this would be valid 844-2345-123456
^[2-9]{1,}[0-9]{2,}\-[2-9]{1,}[0-9]{2,}\-[0-9]{4,}$
should be
^[2-9]{1}[0-9]{2}\-[2-9]{1}[0-9]{2}\-[0-9]{4}$

The key is to look at the value of the submit button. This needs to be unique.
Change around your logic a little and you will have it.
= $now ) {
die('ERROR: Please enter a date of birth earlier than today');
}
// calculate difference between date of birth and today in days
// convert to years
// convert remaining days to months
// print output
$ageDays = floor(($now - $dateTs) / 86400);
$ageYears = floor($ageDays / 365);
$ageMonths = floor(($ageDays - ($ageYears * 365)) / 30);
echo "You are approximately $ageYears years and $ageMonths months old.";
} else if ( isset($_POST['submit']) && $_POST['submit'] === 'Submit Kitten' ) {
$name_cat = $_POST['cat'];
echo "Your Kitten is $name_cat";
} else {
echo <<
Enter your date of birth, in mm/dd/ format:
Enter your kitten's name:
HTML;
}
?>

Jim -
Thanks ever so much!
Here is the code I used, as you suggested.
==
$query = "select * from Intake3 where ";
Maybe I missed it, but you need to have a 1 after the where part in your
select. So...
$query = "SELECT * FROM Intake3 WHERE 1 ";
$allowed_fields = array('Site', 'MedRec', 'Fname', 'Lname',
'Phone', 'Sex', 'Height');
Here you are using two different arrays. Yes, I know, they are
basically the same, but they are truly not the same. In your case, use
$_POST
if(isset($_Request['Sex'])&& trim($_POST['Sex']) != '' )
{
if ($_REQUEST['Sex'] == "0")
{
$sex = 'Male';
}
else
{
$sex = 'Female';
}
}
Looking again at what I sent you before, it would have given you a few
errors if ran like that. Here is a better version of it. For the
above, you can change the logic and get rid of the isset and trim.
Also, make sure when you do a comparison against "0" that it is type
strict using === and not ==. I could pass FALSE or NULL as the value
and it would get by your test. If you look at the definition of empty()
it tells you that if empty is passed: "", 0, "0", NULL, FALSE, array(),
or var $var; in a class that the return of empty will be false. So,
this tells me that I can replace the multiple if/else statements above
with a single as below.
if ( empty($_POST['Sex']) )
{
$_POST['Sex'] = 'Male';
} else {
$_POST['Sex'] = 'Female';
}
The above does the same but without the extra work involved. Once you
have that, the following will work fine.
foreach ( $allowed_fields AS $field )
{
if ( ! empty( $_POST[$field] ) )
{
$value = mysql_real_escape_string( $_POST[$field] );
$query .= " AND `{$field}` = '{$value}' ";
}
}
printf($query);
This is the result I get for the query:
select * from Intake3 where AND `Site` = 'AA'
I can't figure out what is happening.
Would you please help.
Thanks again.
Ethan

Re: [PHP] array question

Hello all!
I have a question regarding arrays and the way I can use a value.
Let's say I have this string:
$s = 'banana,apple,mellon,grape,nut,orange'
I want to explode it, and get the third value. For this I would normally do:
$a = explode(',', $s);
echo $s[2];
That's all fine, but is there a way to get the value directly, without
having to write another line in my script. I mean something like this:
echo explode(',', $s)[2];
or
echo {explode(',', $s)}[2];
I couldn't find out this answer anywhere, that's why I posted here.
Cheers and thanks!
Sure it CAN be done. Nobody laugh too loud here... But...
Outputs: grape
The {3} part is equivalent to the array position. Change that number,
and you change which word will get displayed.

Re: [PHP] HTML id attribute and arrays
What are you trying to accomplish?

Hi,
PHP converts x[a]=b parameter of the HTTP request as an array named x

Unfortunatelly, HTML specification does not allow neither "[" nor "]"
inside the id attribute. Specifically:
* Must begin with a letter A-Z or a-z
* Can be followed by: letters (A-Za-z), digits (0-9), hyphens ("-"),
underscores ("_"), colons (":"), and periods (".")
* Values are case-sensitive
How should I follow the HTML specification while having the passed

Here is what I do if I want to make it a one liner...
PrintString();
echo myNew('CustomClass')->ReturnString('Something Else');
$var = myNew('CustomClass')->ReturnString('And again...');
echo $var;

I also use the following if I want to use the Singleton method of getting my

PrintString();
echo myClass::run()->ReturnString();
$var = myClass::run()->ReturnString();
echo $var;

This should do.
The only problem that I foresee would be an empty "" if you have no
directories returned by glob().
print('');
foreach ( glob('./*', GLOB_ONLYDIR) AS $dir )
print(''.$dir.'');
print('');

Looks to me that you are looking for "chained select boxes". Doing a G search

It has a very good example that shows the concept that you are trying to have
