[SOLVED] strip out part of a string - should be easy enough

[CaptainChainsaw]

Hi all,

 

I need to strip out the "pagenumber" param from the following query string:

 

search.php?pagenumber=2&param0=a

 

I have a search script which is passing any seach params dynamically.  So both these query strings are searching for the letter 'a'.  The problem is that the pagenumber is passed around so it creates another param for it each time the "next page" link is clicked and it screws up the search.

 

search.php?pagenumber=2&param0=2&param1=a

 

Can anyone help with this one? What string functions would be best for this?

 

 

Thanks in advance.

parse_str()?

I tried that function using the following code:

 

public function removeParam($param){
parse_str($this->_querystring,$output);
unset($output[$param]);
return $output;
}

 

I didn't get the desired results as it still creates the 2nd query string.

I think I've got this sorted.

Never Mind.... Forget this post...

 

$str = str_replace("pagenumber","",$url); // doesn't remove the number

// OR

$str = preg_replace("~pagenumber=(.+?)\&~","",$URL);

try

<?php
$test = 'search.php?pagenumber=2&param0=a';
$test = parse_url($test);
parse_str($test[query], $out);
print_r($out);
?>

Alternately

 

<?php

$test = 'search.php?pagenumber=2&param0=a';
list(,$query) = explode( '?', $test );
parse_str( $query, $qVars );

echo $qVars['pagenumber'];

?>

 

Saves you a parse_url call.
