get_cfg_var

Name

get_cfg_var — Gets a PHP configuration option.

Synopsis

string get_cfg_var(variable); string variable: Variable to be retrieved

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

Example 994. Check for location of error log

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