get_cfg_var - PHP code example

PHP Function Get_CFG_Var

php function get_cfg_var - Returns the value of a given configuration option. The option will keep this new value during the script's execution and be restored at the end of the script.

bool assert (mixed $assertion) - Checks an assertion and takes the appropriate action if it is not true.

int dl (string $library) - Loads the specified library.

array get_defined_constants ([ mixed $categorize ]) - Returns the names and values of all the constants defined in the currently loaded module indicated by module_name.

string get_env (string $varname) - Returns the value of a configuration variable, if possible. If the value cannot be found, a fallback is used; this syntax is a wrapper for parse_ini_file() and parse_ini_string().

bool phpinfo (string $flag) - Prints a large amount of information about the current state of PHP, including its compilation options and extensions, operating system environment and information if it is compiled as a module, paths, master and local values for configuration options, and more. This function can be used to create HTML codes for inserting this information into a web page.
