ereg functions are deprecated
While looking at the PHP online reference for ereg, I noticed a huge deprecation notice:
Looks like all of the ereg functions (ereg_replace, etc.) are being removed in the new version of PHP. They are all deprecated in favor of the Perl-compatible functions:
Note: As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an E_DEPRECATED notice.
My codes are littered with ereg functions. Having to port my code over to use the PCRE extension is not going to be fun.
I found in many ereg_replace cases, you can simply surround the pattern with '/' when you convert to preg_replace. For example:
$line = ereg_replace ('\n', '', $line);
eregi_replace is for case-insensitive replacements. To substitute preg_replace for this function call, you'll have to use the 'i' modifier. For example:
$str = eregi_replace ("%7D", "}", $str);
For many cases where you are not searching for regular expression replacements, you can simply substitute str_replace instead. For example:
$str = ereg_replace (">", "%3E", $str);
If you use ereg to determine whether a string contains a regular expression, you can replace the ereg function with preg_match. For example:
$result = ereg ("\[MOVED\] ", $this->pageTitle)
