Problem with !eregi

[Powerz]

Hello.I got some error in my code:

Deprecated: Function eregi() is deprecated in config.php on line 84

 

This is my code

 

if(!eregi( "^[a-zA-Z\-_0-9/-]+$", $type )) unset($type);

if(!eregi( "^[a-zA-Z\-_0-9/]+$", $act )) unset($act);

if(!eregi( "^[a-zA-Z\-_0-9/]+$", $id )) unset($id);

 

Can someone help me what should be changed

Yes, the function has been deprecated as of PHP version 5.3.0

you can use preg_match instead.

 

if(!preg_match( "~^[-a-zA-Z_0-9/]+$~i", $type )) unset($type);
if(!preg_match( "~^[a-zA-Z\-_0-9/]+$~i", $act )) unset($act);
if(!preg_match( "~^[a-zA-Z\-_0-9/]+$~i", $id )) unset($id);

If I am understanding that expression correctly you could simplify that as

preg_match( "~^[\w-/]+$~", $value )

yes, another way of writing it, except that you want to keep the dash immediately following the opening character class bracket so it is not treated as a meta-character. Also, the OP was using eregi(), which performs a case-insensitive search, thus the reason for the appended "i" modifier.

Right, but doesn't the use of \w remove the need to use 'i' for case insensitivity?

yes, my mistake on that part.
