Not Working...

rIkLuNd

Why isn't this code working?

<?php

function code($str)
{
   $str = htmlspecialchars($str);
   $str = ereg_replace("[","<",$str);
   $str = ereg_replace("]",">",$str);
   return $str;
}

$mes = code($text);
echo $mes;

?>

This code outputs:

Warning: REG_EBRACK: in C:\Path\file.php on line 11

Line 11 is:
$str = ereg_replace("[","<",$str);

Please help a stupid newbie!

It would easier to do using str_replace

How would this code look then?

You need to escape the bracket with a backslash, like this:



<?php

function code($str)
{
   $str = htmlspecialchars($str);
   $str = ereg_replace("\[","<",$str);
   $str = ereg_replace("\]",">",$str);
   return $str;
}

$mes = code($text);
echo $mes;

?>

Damn, my backslash got edited out... I'll try again:



<?php

function code($str)
{
   $str = htmlspecialchars($str);
   $str = ereg_replace("\\[","<",$str);
   $str = ereg_replace("\\]",">",$str);
   return $str;
}

$mes = code($text);
echo $mes;

?>

ok... thanx!

str_replace is faster
so replace this:

$str = ereg_replace("[","<",$str);

with this:

$str = str_replace("[","<",$str);

The reason for the speed is that fact that the Server does not have to do a regex search and replace.

oh... thanks for the tip!
