replacing ereg_replace and eregi_replace with preg_replace

[Bl4ckMaj1k]

    $customer_contact_id = preg_replace("`", "", $customer_contact_id);

 

Am I doing something wrong? Every page that used the eregi_function, I changed to have it utilize the preg_function (because I saw a Youtube video telling me to do so). Now, every variable I perform the above on acts as if it doesn't exist. This has totally destroyed my system. What do I need to do here to fix things?

preg functions need pattern delimiters:

 

$customer_contact_id = preg_replace("/`/", "",  $customer_contact_id);

 

However, if you don't need regex, this is easier and faster:

 

$customer_contact_id = str_replace("`", "",  $customer_contact_id);

The video told you to do that because eregi has been deprecated since 5.3.

Worked just fine, thanks!!

Hmm....why do they deprecate functions anyway? eregi_replace still got the job done...what made someone make another function which does the exact same thing?

PCRE (Perl Compatible Regular Expressions) used in preg functions are generally faster than and have additional functionality beyond POSIX which is used in the ereg functions.  Plus, with the popularity of Perl, they may be more widely known and used.

PHP keeps a change log including deprecated functions for each version.  Here is 5.3.x:
