get_cfg_var

string get_cfg_var(string variable) 

Gets a PHP configuration option.

Returns:

Current setting of variable; FALSE on error

Description:

get_cfg_var() checks for a PHP configuration variable and returns the current setting if the variable exists. For example, this function can be used to determine whether adding backslashes is enabled by default, or needs to be performed before database entry. A list of these configuration options can be found in the phpinfo() function, although options set either in Apache or at compile time cannot be accessed using this function.

Example:

Check for location of error log

if (!$cfg = get_cfg_var("error_log")) { echo "error_log not set.\n"; } echo "Error log is in $cfg;
