How to obtain information about server operating system _php tips for PHP

This article is an example of how PHP obtains information about the server's operating system. Share to everyone for your reference, specific as follows:

The following is the basic statement that PHP obtains the current server information.

PHP Program version:

? PHP echo php_version;?>

Zend Version:

? PHP echo zend_version ();?>

MySQL Support:

<?php Echo function_exists (mysql_close)? " Yes ": no";?>

MySQL Database continuous connection:

<?php
Echo @get_cfg_var ("Mysql.allow_persistent")? Yes ": no";
? >

Maximum number of MySQL connections:

<?php
Echo @get_cfg_var ("Mysql.max_links") ==-1? "Unlimited": @get_cfg_var ("Mysql.max_links");
? >

Server operating system:

? PHP echo php_os;?>

Server-side information:

? PHP echo $_server [' server_software '];?>

Maximum upload limit:

? PHP
Echo Get_cfg_var ("Upload_max_filesize")? Get_cfg_var ("Upload_max_filesize"): "Not allowed to upload attachments";
? >

Maximum execution time:

? PHP Echo Get_cfg_var ("Max_execution_time"). " Seconds ";?>

Script run consumes maximum memory:

? PHP

?>
