Need some help with a search replace function I did.

  function search_match($desc,$searchstr)
  {
    $searchar = explode(" ", $searchstr);
    $total = count($searchar)-1;
    for($c=0; $c <= $total; $c++)
    {
      $desc = str_replace($searchar[$c],"<b>".$searchar[$c]."</b>", $desc); 
    }    
   
    return $desc;
  }

Code (markup):

Anyone know how to make this where it will replace it and be non case sensitive? I do a word search for ms swan, it will not bold MS, Ms, Swan, SWan, SWAn, SWAN, etc. It will only bold the ms swan one.
----------
str_ireplace is only for php5 and I am working with php 4.3

 

Read about stripos() function.

Then use strtolower() function to replace easily.

 

strtolower will lower both of them. I want to leave the case alone in the original string the shown string, but just add bold around it.

Thanks for the help. Still trying to figure it out.

 

use

str_ireplace() and not str_replace()

 

lfhost: don't have php 5. Even that would not be replacing it as it was, but as a constant.

 

I know it will lower both of them, But look at this:

<?php
$str = "rsgx gfsd MS SwAn kjh";
$search = "ms swan";

$searchLen = strlen($search);
$where = stripos($str, $search);
$theSame = substr($str, $where, $searchLen);

$desc = str_replace($theSame,"<b>".$theSame."</b>", $str);
?>

PHP:

$str == $desc .
It's the same string, but "ms swan" is bold.

Emm...Here is the full function:

<?php
function search_match($str,$search)
{
	$search = strtolower($search);
	$searchLen = strlen($search);

	$where = stripos($str, $search);
	$theSame = substr($str, $where, $searchLen);

	$desc = str_replace($theSame,"<b>".$theSame."</b>", $str);

	return $desc;
}
?>

PHP:

 

I read somewhere that it was supported on PHP4.
You could always use

http://uk3.php.net/manual/en/function.eregi-replace.php

 

lfhost: hrm.. thanks! I think this might work..

<?php
$pattern = '(>[^<]*)('. quotemeta($_GET['search']) .')';
$replacement = '\\1<span class="search">\\2</span>';
$body = eregi_replace($pattern, $replacement, $body);
?>

Code (markup):

Will have to modify it a bit, but I get the jest of it.
