Is there anyway I can get that to work without having to use multiple lines

[PHP] explode()

[Adam Williams]

I am having a user enter a phrase into a textbox, and then I need to 
seperate the words he has typed into variables so I can use each one 
in an sql statement.  I know I will use the explode() function to do this, 
but how will I know how many variables I've created.  For instance, if a 
user types in 3 words seperated by spaces, how will I know i'll have 
var[0] through var[2]?  how about when they type in 2 words or 4 words?  
How will I know how many words they have typed in?  The only way I can 
think of to do this is:

// $var is the input after being ran through explode()

$i = 0;
while ($var[$i])
{
$i++;
}

I will then take the data they enter and create the sql statement:

$j = 0;

$sql = "select subject from subfile where";

while ($j <= $i)
{
$j++;
$sql .= "suject matches '*$var[$j]*'";

if ( $j != $i)
{
$sql .= " and ";
}
}




but I think there has to be a better way to do this.  any ideas?

[PHP] explode question

[Rol]

Hello all,

I would like to check some names ( @ seperated strings) with this global $PHP_AUTH_USER

I first do
$arrLoginName = explode("@", $row->usr_loginName);

How can I construct a loop which stops and returns true if a match is found?


Any hints would be great.

Many thanks

Roland

[PHP] explode question

[Rol]

Hello again,

I'd better explain better.

I have logon screen Header("WWW-Authenticate: Basic realm=\"whatever\"");
where I would like the compare the user name $PHP_AUTH_USER with the one in
my database
All names  like Mike or mike are @ seperated strings

How can I check the names from this array $arrLoginName = explode("@",
$row->usr_loginName)

and return true if  a name in the var $arrLoginName == $PHP_AUTH_USER

How can I construct a loop which stops and returns true if a match is found?

Any hints would be great.

Many thanks

Roland

Makes perfect sense:

test

Web browsers url encode form elements. If you use a href link like this,
you need to do the URL encoding yourself. A + happens to be a space, in
URL encoding.

So, PHP receives "name=what+ever" and sets $name = "what ever".

It's an HTTP issue.  You only think you're passing "what+ever" in the 
second example; the value actually being passed is "what ever". See

Try echo()'ing $name on the page you passed it to.
Notice anything different? :)

Before you pass values around with a query string, you
should prepare them first by processing them with 
rawurlencode().

if you need to pass special characters (eg. +) in the url, you need to
use a url encoding function like rawurlencode().. or choose another
delimeter which can be passed in the url like these -_.

[PHP] Explode Question

[admin]

I need to explode an array with an array.

$one = array(0 =>'golf', 1 => 'field');
$two = array(0 => "On the golf course or in the field of clover");


$array_exp = explode($one, $two);

print_r('');
print_r($array_exp);
print_r('');

Notice: Array to string conversion.


I have done this before but it is slipping my memory how I did it.
I do NOT want to foreach over the initial array and read the second array for 
each position.
I am not even sure I used the explode function.

[PHP] explode () question

[Malcolm]

  Hello All,

  I'm having trouble with this;

$rint1= rtrim($rintydata);
 echo $rint1;
 $rint2= explode(":", $rint1);
  The data starts like this (from and email, there are many) ;

 Time: November 9th 2003, 10:37AM - PST
 IP Address: xx.xx.xxx.xxx
 Browser Type: Opera/7.20 (Windows NT 5.1; U)  [en]
 Referer:
  The problem is that when I do this ;

while( $res=each($rint2) )
{
  echo "$res[1]";
};
the colon in Time messes things up.

 here is the result ;

  I can't figure out how to do an ereg that will replace just the colon in 
Time nor can I find a way to make explode ignore it.  This may even be a 
completely wrong approach, any help would be appreciated.

Use count() http://www.php.net/count

Counts the array ...

This will do it:

$dim = sizeof($arrLoginName);
for ($nr = 0; $nr < $dim; $nr++) {
if (match) {
return 1;
}
}

[PHP] explode won't explode

[Tom Beidler]

I have the following code that doesn't seem to "explode." I'm trying to make
a field that looks like 21,23,25,27 or small,medium,large,x-large into a
pulldown menu with the individual item broken out.

if (($size != "") && ($size != "n/a")) {
   $sizearry = explode(",", $size);
   while (list($key,$value) = each($sizearry)) {
   $size_option_block .= "$size\n";
}

The interesting thing (and probably the problem) is that I have very similar
code just before it that works fine. Here's the code that appears just
before and works.

if (($color != "") && ($color != "n/a")) {
   $colorarry = explode(",", $color);
   while (list($key,$value) = each($colorarry)) {
   $color_option_block .= "$value\n";
}

I'm not that familiar with explode. Are my $key and $value variables
conflicting?

[PHP] explode() - quick question

[Phil Schwarzmann]

Im trying to take this string, "hello", and explode it into an array
with each cell in the array containing one character.

$array[0] = 'h'
$array[1] = 'e'
etc..

How does this work?  When is use...

$character = explode('', $string) or
$character = explode($string)

...it doesn't seem to work.  ANY HELP!?!?  THANKS!!

[PHP] Explode and Trim

[Joshua E Minnie]

I am parsing through a text file and using explode to convert the string to
an array.  The problem seems to be at the end of the string, when I check to
see if the last element in the array is empty it tells me that it is not.
The problem comes because the last element should be empty because all that
was after the separator was white space.

---Sample text file---
AL:123 2nd Ave.:SomeCity:(123) 456-7890:(123) 456-1234:::
MI:293 3rd St.:Another City:(123) 345-2839:(123) 384-0398:::
MI:437 4th Ave.:Yet Another City:(123) 283-4839:(123) 458-4843:::
---End of text file---

---Code snippit---
$stores = file($storelist);
for($i=0; $i\n";
  $stores[$i] = explode(":", $stores[$i]);
}

reset($states);
while(current($states) && current($stores)) {
  for($i=0; $i".$states[$stores[$i][0]]."\n";
  $state = 1;
}
echo $stores[$i][1].", ".$stores[$i][2]."Phone:
".$stores[$i][3]."Fax: ".$stores[$i][4]."\n";
if(!empty($stores[$i][5])) echo "Email: ".$stores[$i][5]."\n";
if(!empty($stores[$i][6])) echo "Web site: ".$stores[$i][6]."\n";
if(!empty($stores[$i][7]) && $stores[$i][7] != "") echo "Additional
notes: ".$stores[$i][7]."\n";
echo "";
  }
}
---End of code snippit---

Here is the URL of where the code is being used:
www.wildwebtech.com/acs/nuven/stores.php.  The additional notes should only
show up if there were additional notes.

The desired result is.

[2] = > "of colver";
);

I am just not sure the delimiter can be an array in the Explode function.

explode() takes three parameters; string, string, [int]. Where [int] is
optional.

Ex:
$ipList = '192.168.1.0,192.168.1.1,192.168.1.2';
$ipList = explode(',',$ipList);

Returns an array of strings:

Array
(
[0] => 192.168.1.0,
[1] => 192.168.1.1,
[2] => 192.168.1.2
);

[PHP] explode a string

[Sebastian]

$string = '4:gaming,5:hardware,3:software,8:security';

what is the best way to explode then loop this string after its taken apart.

output should be something like:

$id = 4
$cat = gaming

etc..

im just looking for the best/fastest way to do this. the string can grow to
200 or so bytes, maybe more.

should i list(), while(), explode it, or should i explode it and foreach it?
or..?

thanks.

[PHP] explode a string

[Rory Browne]

Sorry jocham, for you getting this twice.

I'd assume foreach is recommended because it lends to more readable
code. More readable code, is generally considered better code.

Personally I'd disagree and use while( list() = each() ), because it
doesn't create a copy of the array in memory, especially for the
array. If you're dealing with an array where the elements are large,
or multi-dimentional, you may want to consider a different approach,
such as assigning by reference, like:

for($keys = array_keys($sample_array); $key = each($keys), $val =&
$sample_array[$key]; )

but that is very ugly untested code(and I'm drunk), so I wouldn't
recommend you copy n paste it.

besides for the sake of 200 bytes, with an average of around 5
characters per word, it pretty much doesn't matter, which you use.
Even something as crappy as ASP would easly deal with 200b.

Re: [PHP] explode(" ", $pizza)

[Sascha Braun]

Hi,

i found something like:

var s = "This,is,a,String";
lenght = s.lenght;
document.write(s.bold());
t = s.substring(2,4);
a = s.split(","); // This line is the most interesting one ;))

document.write(a[1]); // should write the word 'is'

Dont know if it works, i just looked in one of my old books.

The Book where i found the answer is from O'Reilly: Javascript
the defenetive reference or some like that, another very very good
book is Dynamic HTML from O'Reilly, you should find all infor-
mation you need there.

Good luck!

RE: [PHP] explode(" ", $pizza)

[Tim]

The following example illustrates the use of the split method.

function SplitDemo(){
   var s, ss;
   var s = "The rain in Spain falls mainly in the plain.";
   // Split at each space character.
   ss = s.split(" ");
   return(ss);
}

[John Taylor-Johnston]

$P1OC1Q1 = "1¶some text or some comment";

echo "Your score is: "; $score=split($P1OC1Q1,"¶"); echo

Do I have to go through all that to get score[0] ?

$rint1= rtrim($rintydata);

  I can't figure out how to do an ereg that will replace just the colon 
in Time nor can I find a way to make explode ignore it.  This may even be 
a completely wrong approach, any help would be appreciated.
Do you first split the lines?
What about a simple strpos and substr?
$colon=strpos(':',$res) will get you the position of only the 1st colon.
then strpos ($res, 0, $colon-1) will get you the 1st part
and strpos ($res, $colon, strlen($res))  the second part.
disclaimers: not tested. not guaranteed to be working. just a suggestion. 
check the manual to fix it.

What you'll probably want to do is write a regex that changes the colon
you're trying to separate on into something else.

Go from:

Time: ...
Other Thing: ...
Different: ...

To:

Time% ...
Other Thing% ...
Different% ...

After you've done this you can easily explode() based on the %.

I'm not very good with regex's off the top of my head so I suggest you
get The Regex Coach (easily found via google) and experiment.

[PHP] explode and PATH_SEPARATOR

[Francisco M. Marzoa Alonso]

Taking this code:


define (PATH_SEPARATOR, "/");
$String="Root/One/Two/Three/Last";
$arr = explode ( PATH_SEPARATOR, $String );
var_dump ( $arr );
$arr = explode ( "/", $String );
var_dump ( $arr );
?>

It works fine in second case returing a five elements array, but in the 
first one it returns an array with just one elemen that's the source 
string itself. I've test it also changing PATH_SEPARATOR by SEPARATOR in 
both cases, and it works nice... Is PATH_SEPARATOR any kind of reserved 
word or so?

Thx.

I think you've used the wrong varaible between . You should
have $value, but you've put in the original variable: $size.

You need to explode the array:

I think what yo wrote should be working fine for you.

My way of your code:




foreach(file($storelist) as $line_num=>$line_data) {
foreach(explode(':', $line) as $key=>$val) {
$val = trim($val);  // remove whitespaces around

// now you are inside each element of your

// combine your rest of the code and work it out the way
you need it.

Unfortunately it doesn't.  That is why I am kind of puzzled by the

Re: [PHP] Explode and Trim

[Joshua E Minnie]

It works great using the foreach statements, but for some reason couldn't
make it work the other way.  Oh well, no one ever said there was only one
way to do things when programming.  Thanks for your help.

[PHP] explode in mysql query

[Sebe]

i have a mysql column that looks like this:

groups
---
12,7,10,6,14,11,2

is it possible to select the row if `groups` contain 7 or 14?
trying to avoid running two queries and running explode() on it.

i don't remember but i thought there was a way to use explode() on 
something like this within a single query.

while is faster than foreach. check the iterator section in SPL for details.

200 bytes is chump-change.

It really doesn't matter how you do this, within reason.

are we talking about iterating over an Iterator or an array()?
Harry Fuecks is talking about iterating over a php5 object..., your
question/example features a straight array.

You should never loop through so many things in PHP that it matters in the
first place :-)

[shrug]

That's probably because they're tired of people not understanding the
internal pointer array, and asking FAQs about it.  Or maybe not.  Ask them
why they prefer it.  I sure don't know.

None of those are function calls.

They are all language constructs.  Okay, each() *might* be a function...

I'm not sure how much difference there is in the number of language
constructs used, nor if they are even comparable in sheer numbers the way
functions are.

foreach is probably slower, I think, because it creates a *copy* of the
array to work on, so it won't mess up the original and its internal
pointer.

Again, with 200 bytes, you are wasting your time to worry about any of this.

I'm an old dog, and I don't quite understand for sure how this new-fangled
foreach thingie works.  I'd spend more time looking it up and reading
about it than just typing what I *know* works. [shrug]

ah yes, lang constructs rather than function calls.
foreach is probably slower, I think, because it creates a *copy* of the
array to work on, so it won't mess up the original and its internal
pointer.
unless I'm mistaken its a copy-on-change, so unless you are changing the
the array inside the loop you don't suffer the actuall copy penalty - can anyone
knowledgable on php internals confirm or deny this?
actually now I think of it you can use references in a foreach statement:
php -r '
$arr = array(1,2,3);
foreach($arr as $k => &$v) {
$v++;
}
var_dump($arr);
'
which suggests that a copy is not (always?) being made...
Again, with 200 bytes, you are wasting your time to worry about any of this.
true, It's purely a theoretical interest - deeper understanding is alway 
nice :-)
...its not even my 200 bytes we're talking about ;-)

on the while loop, all else being equal the foreach loop has to be faster
(given that calling functions is relatively very expensive)...
or is foreach() _really_ heavy when compared to while()?

Why don't you just benchmark it on your own machine and find out?
because I don't have the skills to write a test/benchmark that I _know_ is
kosher (and not skewed by a million of my misconceptions, besides I run so much
stuff on my machine that speed can be severely affected by things like
apache or firebird running in the background
that and I lazy ;-) (or I just don't care enough to invest time investigating 
this)

explode by ","
$output1 = explode(",",$string);

use a loop and explode  array $output1 by ":"

Looks like a really simple piece of code except for the cryptic variable 
names.

Do I have to go through all that to get score[0] ?

Kind of hoping to do shorten it like this:

echo "Your score is: ".$score[0]=split($P1OC1Q1,"¶")."\n";

No such hopes?

I think reset(split()) should work for getting the first element.

Ok, but what happens when $P1OC1Q1 = "". It errors out.

$P1OC1Q1 = "";#left blank
$P1OC1Q2 = "1¶bunch of text";
$P1OC1Q3 = "1¶bunch of text";
$P1OC1Q4 = "1¶bunch of text";
$P1OC1Q5 = "1¶bunch of text";
$P1OC1Q6 = "1¶bunch of text";

Re: [PHP] [php] explode that :) !

[John Taylor-Johnston]

Actually this does not work:

echo split($P1OC1Q1,"¶");

There are two variables in $P1OC1Q1 = "1¶a bucnh of text"
I want to split $P1OC1Q1 and get "1" as a numeral for a calculation. I was looking for 
a cleaner way to do it.

$P1OC1Q1 = "1¶some text or some comment";
echo "Your score is: "; $score=split($P1OC1Q1,"¶");
echo $score[0]."\n";

My problem becomes more difficult when $P1OC1Q1 = "";
Split errors out.

substr($P1OC1Q1, 0, strpos($P1OC1Q1, '¶')-1)

That will return every thing to the left of '¶'. and '' if nothing
is there without complaining.

[PHP] Explode and multple lines

[Sweet T]

Hello,

I am using php to explode the lines of a text file (delimited by a 
comma), break it into an array, and echo only one of the array elements. 
I have accomplished all of this, but it only echos the text for one 
line. How do I get php to scan multiple lines? I tried to introduce a 
line count, but I can't find any information on how I can create a loop.

An example would be:

For the below text file, I want to echo

dept, 10, 20, 40 ,30

empid, name, job, dept
10,Wilma Tucker, Sales Engineer, 10
43,James Whitmore, Unix SA, 20
50,Tricia Williams, Systems Developer, 40
427, Barry Regar, Administrative Assistant, 30
Thanks!

[PHP] explode, split, or what?

[Kyle Babich]

Thank you to those of you who helped me with my last problem earlier today.

Now I have a text file (setup.txt) that has a series of values all seperated by 
\r\n's.  Inside of another file I'm trying to read setup.txt into $rawSetupData and 
explode that with \r\n's into an array called $setupData.  My problem is that the 
explode function doesn't seem to be doing anything, and neither is split which I tried 
also.  Here is my code:

setup.txt
***
John\'s X Log
10
5
example.com
treeclimber56
ab3c45def
***

test.php
***

***

Actual results of running test.php
***
John\'s X Log 10 5 example.com treeclimber56 ab3c45def 61
***

Desired reults of running test.php
***
John's X Log
***

Other problem:
In the actual results of running test.php where is the 61 coming from?

Thank you,

Yes. You need to somehow differentiate between the different columns and
rows. What I suggest you do is change every other + to something else
like a ; and then split on that.

Without knowing any other way to do this I would use a regex to skip the
first + and change second one, repeating this until the end of the
string.

Then you can explode() on + and ;.


hth,
Chris.

You could try explode("\n", $stuff);, but if you are wanting to read
information from a file and store each line in an array, the file() function
does exactly that.

PATH_SEPARATOR is is a predefined constant, so you'll need to use

[PHP] Explode, Arrays and Checkboxes

[Matt Winslow]

I'm not new to PHP, but I have very little experience with arrays.  I have comma 
separated values in a database, that I need to pull out, explode into an array, then 
check certain checkboxes if they exist.

I have two variables:

$x = "2,10,34"
$y = "28,15,16"

I need to explode them both, so that the values of $x are they keys, and the values of 
$y are the values.  Is that possible?

I have a form, with checkboxes that are named $product[1] through [40].  Next to them 
are textboxes labeled $price[1] through [40].  How would make the form, when it loads, 
have $product[2], [10], [34] checked, with $price[2], [10], and [34] equal to "28", 
"15", and "16" respecively.

Any help would be greatly appreciated.

[PHP] Explode-update-implode not working

[Bob McConnell]

At least not the way I expected it to. Apparently I am doing something
wrong, but I can't find anything specific that explains it. This is in
PHP 5.2.6.

Here is the sequence I am trying to implement without the database
portion. (This is typed in since the VNC I am using doesn't support
pasting from a Linux client to a MS-Windows server.)

-
$buff = "key1|value1~key2|value2";

$lines = explode ("~", $buff);

foreach ($lines as $kvpair) {
   $line = explode ("|", $kvpair);
   if ($line[0] == "key1") {
  $line[1] = "value3";
  $kvpair = implode ("|", $line);
  break;
   }
}
$newbuff = implode ("~", $lines);
-

$kvpair is modified, but that change is ignored by implode() with
$newbuff still containing "key1|value1".

So why doesn't the change to $kvpair get brought in by implode? What
should I do to update that value?

you'd better put the groups info in a separate table, referenced by this
table. then you can simply

SELECT t1.* FROM whatever t1, groups t2 WHERE t1.id=t2.whatever_id AND
(t2.group=7 OR t2.group=14);

I would think a more efficient strategy would be a simple string 
search.  If you append a comma to the beginning and the end of your 
list so it becomes:


,12,7,10,6,14,11,2,

then you can search for:

,#,

where # is the desired integer.

Therefore you could use the MySQL syntax:

WHERE CONCAT(',', `groups`, ',') LIKE '%,7,%'
   OR CONCAT(',', `groups`, ',') LIKE '%,14,%'

thanks for the idea.. i also just came up with a solution using mysql 
FIND_IN_SET


eg: FIND_IN_SET('7', groups) OR FIND_IN_SET('14', groups)

You should never have tables that look like this.  If this is early in
the application development, look into 3rd normal form for SQL tables
(don't worry about 4th or 5th).  In a nutshell, here is what you should
be doing: you have a many to many relationship (big thing to note).
Whatever holds groups (lets call it foo) to groups.

So you should do something like this:

===
Foo <--A table
===
Id <-- columns
groups
Coln

===
Groups
===
Id
Col1
Col2
Col3

So then you create a 3rd table named

===
Foo_has_groups (or groups_has_foo, whichever sounds best)
===
Fooid
groupsid

So then, you can do much more powerful queries, with much less overhead.

Such as: 
SELECT t1.* FROM foo t1, groups t2 WHERE t1.id=t2.whatever_id AND
(t2.group=7 OR t2.group=14);

If you are reluctant to do any of these optimizations to your database,
then you better not worry about anywhere in your PHP code to do _ANY_
optimizations.  This will be your system bottleneck!  99% of the time
(maybe less) when you get a slow application, your bottlenecks will
be in your sql queries/design. 

Hopefully that all made sense

It's a MySQL question, but I suspect that the REGEXP operator in MySQL
would let you find these with something like:

groups REGEXP '\\b7\\b' or groups REGEXP '\\b14\\b'

The \\b being a word boundary, if I remember correctly...

a sensible use of foreach and if can easily do so.

$final = array();
$Y = explode(',', $y);

foreach(explode(',', $x) as $key => $val ) {
  $final[$val] = $Y[$key];
}

var_dump($final);

What is the relationship between the $x,$y and $product,$price?
I'm not sure I quite grasp what your trying to do.

If I understand correctly, the situation you describe ends up not
being a one-one relationship. So a user could select 4 prices with
3 products or vice versa. Which will make things difficult to match
up products/prices.

Sometimes that array documentation can be so overwhelming.

[PHP] Explode a variable into each character

[Brandon Orther]

Hello,

I have a string of 1034 and I want to have an array that has each number in
an element.(ex: num[0] = 1, num[1] = 0, num[2] = 3 num[3] = 4) Is there a
way to explode a string by each character?

Thank you,

See the second note at
http://www.php.net/manual/en/control-structures.foreach.php

Either of these should do what you want:



 $kvpair) {
  $line = explode ("|", $kvpair);
  if ($line[0] == "key1") {
 $line[1] = "value3";
 $lines[$key] = implode ("|", $line);
 break;
  }
}
$newbuff = implode ("~", $lines);
?>

Doh! I knew it would be something simple that I had overlooked. I recall

that was then ...

Thank you, the code is working better now. I just wish I were.

That's exactly correct. Except I /think/ you should use "\n" instead of '\n'.

Thank you for the reply... =)

I'll check this... BTW:

array explode ( string $delimiter, string $string [, int $limit] )

So, I was wrong...
The right way, probaly, is:

$str=explode("\n",$_POST["my_text"]);


Thank you very much.
