You must use preg_match instead of ereg because the last one is deprecated.
Replacing it is not a big deal:
ereg( "[][{}()*+?.\\^$|]", $_REQUEST['name'] )
will become:
preg_match( "/[][{}()*+?.\\^$|]/", $_REQUEST['name'] )
p.s. I had to modify more than one hundred files while I was porting my old project to PHP 5.3 to avoid manually modifying I've used following script to do it for me:
function replaceEregWithPregMatch($path) {
$content = file_get_contents($path);
$content = preg_replace('/ereg\(("|\')(.+)(\"|\'),/',
"preg_match('/$2/',",
$content);
file_put_contents($path, $content);
}
I hope it helps.
