There must be some clever workaround using global scope variables and eval(). I just can't think of it yet.

This means that the $variable1, $variable2, etc. variables are only references to the copy made with func_get_args(), rather than to the variables passed to the first function.

Yes, that would be possible, however that would involve an API change - as now functions would have to get their variables out of an array rather than just a normal variable defined in the function. At the moment I've just decided to add more $var_x parameters. btw: have you met call_user_func_array() yet? (not that it would solve the problem because it doesn't 'do' references) - also, it's manual page offers a hack for the reference problem your working on. Yes, I briefly considered using it. Another method I tried was building a list of parameters and using eval() to call the function. Since I can't get the variables by reference, however, I've stuck with just passing $var_1, $var_2, etc. to the function. Thanks for your comments. I think the amount of effort I would spend learning how to use the reflection API compared to just using a defined number of variables labelled in sequence is not worth it. If there was another way, perhaps...

[PHP] Passing an indefinite number of parameters by reference
Hi, Currently I have a function which accepts a limited number of parameters: call_function($function_name, &$var_1, &$var_2); I wish to modify the function to accept an indefinite number of parameters, which may or may not be references. The function call_function() then calls the function specified in $function_name, with the variables passed as parameters to that function. Is this possible? Thanks for any help which can be offered.

How do I find an exact match of a string with preg_match?
Example:
String1: www.test.com/
String2: www.test.com/somepage.php?param1=true
How do you write the regexp to only return String1 and not String2 when you
match against "www.test.com" ??
You should use the ^ and $ characters which signify the start and the
end of the string respectively.
For example:
$matched = preg_match('/^www\.test\.com$/', $string);

[PHP] Cannot Load DLLs (WinXP, Apache 2, PHP 5)
Hi, I can't get PHP to load php_mysql.dll, required to use the mysql_*() functions. I have tried a variety of values for extension_dir, including "C:/php/ext", "C:\php\ext", "C:\php\", "./ext/", "ext/". I have copied php_mysql to all these directories, but it is not loading it. PHP is stored in C:/php, and works perfectly apart from not finding the MySQL dll file. If you could advise me for how to get PHP to load this DLL, I would be very grateful!
