Get_cmd_var () and ini_get () Get the configuration value. What is the difference between get_cmd_var and ini_get?

Get_var_cfg (): The value is the value in the configuration file.
Ini_get (): The current value.

For example
Ini_set ('smtp ', '192. 160.0.24'); // change the current SMTP value.
Print get_cmd_var ('smtp '); // return localhost
Print ini_get ('smtp '); // return 192.160.0.24

Code

<? Php
/*
Our php. ini contains the following settings:

Display_errors = On
Register_globals = Off
Post_max_size = 8 M
*/
Echo 'display _ errors = '. ini_get ('display _ errors'). "\ n ";
Echo 'register _ globals = '. ini_get ('register _ globals'). "\ n ";
Echo 'Post _ max_size = '. ini_get ('Post _ max_size'). "\ n"; // post content submission restrictions:
Echo 'Post _ max_size + 1 = '. (ini_get ('Post _ max_size') + 1). "\ n ";
Echo 'Allow _ url_fopen = '. (ini_get ('Allow _ url_fopen'). "\ n"; // use the URL to open the file:
?>

 

This script will produce:

Display_errors = 1
Register_globals = 0 // nothing on my machine
Post_max_size = 8 M
Post_max_size + 1 = 9
Allow_url_fopen = 1

 

 

Code

<? Php

Echo 'Allow _ url_fopen = '. (get_1__var ('Allow _ url_fopen'). "\ n"; // use the URL to open the file:

?>

 

 

Output

Display_errors = 1
Register_globals =
Post_max_size = 8 M
Post_max_size + 1 = 9
