@andre4s_yFeb 24.2008 — try :
[code=php]
$output = preg_split("/=/",$string, 2);
//or
$output = preg_split("/(=)/",$string, 2,PREG_SPLIT_DELIM_CAPTURE);
//or
preg_match("/(^.+=)(.+$)/U",$string,$output);
[/code]
That first line code split the $string into array of 2, without include the delimiter.

That second line code split the $string into array of 3, with include the demiliter between.

That third line matching the $string first and capture the subpattern.

For example :
[code=php]
<?php
$string = "www.site.com/page.php?q=SPLITHERE&cat=0&others=1";
$output = preg_split("/=/",$string, 2);
print_r($output);
$output = preg_split("/(=)/",$string, 2,PREG_SPLIT_DELIM_CAPTURE);
print_r($output);
preg_match("/(^.+=)(.+$)/U",$string,$output);
print_r($output);
?>
[/code]
It will output :

Array ( [0] => www.site.com/page.php?q [1] => SPLITHERE&cat=0&others=1 ) Array ( [0] => www.site.com/page.php?q [1] => = [2] => SPLITHERE&cat=0&others=1 ) Array ( [0] => www.site.com/page.php?q=SPLITHERE&cat=0&others=1 [1] => www.site.com/page.php?q= [2] => SPLITHERE&cat=0&others=1 )

@ZiplineFeb 24.2008 — This may not be the fastest way to get to the result you were looking for but I was able to do it successfully using explode just as a learning exercise. I have included a full sample script of how I did it including output.


[code=php]
<?PHP

/*******************************************************************************

SCRIPT OUTPUTS

Section1: www.site.com/page.php?q=
Section2: SPLITHERE&cat=0&others=1
Item in q=: SPLITHERE
Rest of Querystring: &cat=0&others=1

*******************************************************************************/

//URL TO SPLIT
$url = "www.site.com/page.php?q=SPLITHERE&cat=0&others=1";

//SEPERATE BASED ON ?q= JUST q or ? or = MAY APPEAR ELSEWHERE SO USING "?q=" IS LEAST LIKELY TO FIND A DUPLICATE
$pieces = explode("?q=",$url);

//BUILD THE TWO SECTIONS
$section1 = $pieces[0];
$section2 = $pieces[1];

//DISPLAY SAMPLE USING THE DATA
echo("Section1: {$section1}?q=");
echo("<br />");
echo("Section2: {$section2}");

//NOW WE CAN USE THE SAME TECHNIQUE TO GET RID OF "SPLITHERE"
$pieces2 = explode("&",$section2);

//START A COUNT
$n = 1;

//OPEN SECTION 3
$section3 = "";

//LOOP PIECES
if(is_array($pieces2)) {
foreach($pieces2 as $piece) {
if($n == 1) {
$item = $piece;
} else {
$section3 .= "&{$piece}";
}
$n++;
}
}

//DISPLAY THE RESULTS
echo("<br />");
echo("Item in q=: {$item}");
echo("<br />");
echo("Rest of Querystring: {$section3}");

?>
[/code]

@NogDogFeb 24.2008 — My suggestion from the [url=http://phpbuilder.com/board/showthread.php?t=10351495]same thread at PHPBuilder.com[/url]:
[code=php]if(preg_match('/^([^=]+=)[^&]*(&.*)?/', $text, $matches))
{
echo $matches[1]."<br />n".$matches[2];
}
else
{
user_error("Match failed");
}[/code]

Success!
