Fix `ereg is deprecated` errors in PHP 5.3

If you upgraded to PHP 5.3, chances are high you’re going to run into a few warnings or deprecated function messages.
An example is the ereg family of functions, which are gone for good, as they were slower and felt less familiar than the alternative Perl-compatible preg family.

To migrate ereg():

ereg('\.([^\.]*$)', $this->file_src_name, $extension);

becomes

preg_match('/\.([^\.]*$)/', $this->file_src_name, $extension);

Notice that I wrapped the pattern (\.([^\.]*$)) around / /, which are RegExp delimiters. If you find yourself escaping / too much (for an URL for example), you might want to use the # delimiter instead.

To migrate ereg_replace():

$this->file_dst_name_body = ereg_replace('[^A-Za-z0-9_]', '', $this->file_dst_name_body);

becomes

$this->file_dst_name_body = preg_replace('/[^A-Za-z0-9_]/', '', $this->file_dst_name_body);

Again, I just added delimiters to the pattern.
If you are using eregi functions (which are the case-insensitive version of ereg), you’ll notice there’re no equivalent pregi functions. This is because this functionality is handled by RegExp modifiers.

Basically, to make the pattern match characters in a case-insensitive way, append i after the delimiter:

eregi('\.([^\.]*$)', $this->file_src_name, $extension);

becomes

preg_match('/\.([^\.]*$)/i', $this->file_src_name, $extension);

We had a similar issue, but our ereg was comparing the contents of a variable to something else – ereg($AllowedTypes,getExt($sFileName). I found a workaround that may help alot of people here…

What preg_match (the replacement for ereg) is looking for is delimiters around the value. THis works great, unless you have a variable that’s used elsewhere and changing the value won’t work.

What I did was to write the line as such:

preg_match(“#”.$AllowedTypes.”#”,getExt($sFileName)

effectively enclosing the value in #s as the delimiter. BTW – the ‘/’ is not the required delmititer, it can be just about anything, as long as it’s the same on both ends. Adding the # front and back did the trick. A hack? Yeah, probably, but it does work. Saved my ass, for sure.

I’m having troubles using preg_match() on a constant.
How to convert this old line? BASEURL is a constant.

eregi(BASEURL, $_SERVER['HTTP_REFERER'])

Set the error reporting to E_ALL ^E_DEPRECATED where it is currently being set to E_ALL

change error_reporting(E_ALL); to
error_reporting(E_ALL ^E_DEPRECATED);

and everything will be perfect.

Hi!

I use sql_regcase, that is is deprecated.

Did you know an sql_regcase alternative ?

Example (to remove sql syntax):
$string = preg_replace(sql_regcase(“/(from|select|insert|delete|where|drop table|show tables|#|\*|–|\\\\)/”),”",$string);

Thank you!

  Sorry for the newbie question…
  
  This is the answer:
  
  $string = preg_replace(“/(from|select|insert|delete|where|drop table|show tables|#|\*|–|\\\\)/i”,”",$string);
  
  This is because ’sql_regcase’ just make the regular expression for case insensitive match, so… just put ‘i’ in the last ‘/’.
  
  Simple… but, why I don’t saw this before…
  
  Thank you very much!

Hi, thanks for your writing. I fixed almost all deprecations as your guide, but except this code:

if (preg_match(‘^’.$arrParam[0].’=', $value))

When I put / / as delimiter before and after ^ to become:

if (preg_match(‘/^/’.$arrParam[0].’=', $value))

I keep getting error as:

Unknown modifier ‘r’ in C:/Program Files/EasyPHP5.3.0/www/taskfreak/include/classes/tzn_generic.php

Note: tzn_generic.php is the file I put above code.

Please help me.

Many thanks,

Hi.

Can you please tell me what should I change in the code below to make things work:
$check_url = str_replace(“\”", “”, $check_url);
if ((eregi(“]*script*\”?[^>]*>”, $check_url)) || (eregi(“]*object*\”?[^>]*>”, $check_url)) ||
(eregi(“]*iframe*\”?[^>]*>”, $check_url)) || (eregi(“]*applet*\”?[^>]*>”, $check_url)) ||
(eregi(“]*meta*\”?[^>]*>”, $check_url)) || (eregi(“]*style*\”?[^>]*>”, $check_url)) ||
(eregi(“]*form*\”?[^>]*>”, $check_url)) || (eregi(“$[^>]*\”?[^)]*$”, $check_url)) ||
(eregi(“\”", $check_url))) {

I got this error:

It’s worth noting that whilst ereg returns FALSE when there is no match, preg_match returns 0.
