note 33425 added to function.str-replace

here is a function to highlight a part of a string. Unlike str_replace, it is both case insensitive, and maintains the case of the highlighted text. function highlight($x,$var) {//$x is the string, $var is the text to be highlighted if ($var != "") { $xtemp = ""; $i=0; while($i<strlen($x)){ if((($i + strlen($var)) <= strlen($x)) && (strcasecmp($var, substr($x, $i, strlen($var))) == 0)) { $xtemp .= "<b>" . substr($x, $i , strlen($var)) . "</b>";//this version bolds the text. you can replace the html tags with whatever you like. $i += strlen($var); } else { $xtemp .= $x{$i}; $i++; } } $x = $xtemp; } return $x; } Example: $string = "AaBbCcDd"; $string = highlight($string, "bc"); echo $string; //AaB<b>bC</b>cDd ---- Manual Page -- http://www.php.net/manual/en/function.str-replace.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+33425 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+33425&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+33425&report=yes
