Hi
this is my first post
I hope finaly some one will answer my question

I'm writing a code that replace some chars with others

the question is: can I give ( str_replace ) some thing to tell it to ignore some differences betwen the two strings, I meen something like special chars..??

I found a function which ignores differences in spacing (like tab, carriage return, line feed, etc.)

But I need to ignore more differences such as ( special cahrs I use, they are almost non english letters )

please some one tell me how to do that or how to make the function bellow Ignore and chars I want

Thanks a lot every body

PHP Code:

<?php 

function str_rep($srcfor,$chwith,$mystr) 

{ 

   if(strlen($mystr) == 0) 

       return ""; 



   $tok  = strtok($srcfor," \n\t\r"); 

   $strsrc = array(); 

   $idxsrc = array(); 

   $i = 0; 

   while($tok) 

   { 

       $strsrc[$i] = $tok; 

       $pos = strpos($srcfor,$tok); 

       $idxsrc[$i]=$pos; 

       $tok = strtok(" \n\r\t"); 

       $i++; 

   } 



   $tok2  = strtok($mystr," \n\t\r"); 

   $str = array(); 

   $idx = array(); 

   $j = 0; 



   while($tok2) 

   { 

       $str[$j] = $tok2; 

       $pos = strpos($mystr,$tok2); 

       $idx[$j]=$pos; 

       $tok2 = strtok(" \n\r\t"); 

       $j++; 

   } 



   for($m=0;$m<$j;$m++) 

   { 

       if(strcasecmp($strsrc[0] , $str[$m]) == 0) 

       { 

           for($l=1;$l<$i;$l++) 

           { 

               if(strcasecmp($strsrc[$l],$str[$m+$l]) != 0) 

                   break; 

           } 

           $l--; 

           if(($l+1) == $i) 

           { 



               $new_str=substr($mystr,0,$idx[$m]); 

               $new_str .= $chwith; 



               $index = $idx[$m+$l]+strlen($str[$l+$m]); 

               $len = strlen($mystr)-$index; 



               if($len > 0) 

                   $new_str .= str_rep($srcfor,$chwith,substr($mystr,$index,$len)); 



               return $new_str; 

               break; 

           } 



       } 

   } 



   return $mystr; 

}
