Hrm. What's $A created for if you don't use it? When I run this script:

Code:
mute@flo-rida:~/temp/Johnny2518$ cat input
Hello World!
mute@flo-rida:~/temp/Johnny2518$ ./script '|*' L input
|*
input
LHLeLlLlLoL LWLoLrLlLdL!L

What do you see when you run it? As you see the results are not as expected, but the file is certainly not empty. Show your output please?

mb_eregi_replace - Replace regular expression with multibyte support ignoring case

SYNOPSIS
string mb_eregi_replace (string $pattern, string $replace, string $string, [string $option = "msri"]) DESCRIPTION
Scans $string for matches to $pattern, then replaces the matched text with $replacement. PARAMETERS
o $pattern - The regular expression pattern. Multibyte characters may be used. The case will be ignored. o $replace - The replacement text. o $string - The searched string. o $option -$option has the same meaning as in mb_ereg_replace(3). RETURN VALUES
The resultant string or FALSE on error. NOTES
Note The internal encoding or the character encoding specified by mb_regex_encoding(3) will be used as the character encoding for this function. Warning Never use the e modifier when working on untrusted input. No automatic escaping will happen (as known from preg_replace(3)). Not taking care of this will most likely create remote code execution vulnerabilities in your application. SEE ALSO
