If you have a file, and you want to read the entire file into a single string, you can use the file_get_contents() function. It opens the specified file, reads all characters in the file, and returns them in a single string. Here is a PHP script example on how to file_get_contents():
<?php
$file = file_get_contents("/windows/system32/drivers/etc/services");
print("Size of the file: ".strlen($file)."n");
?>
This script will print:
Size of the file: 7116
session_id() returns the session id for the current session.
It’s how they handle failures. If the file is not found by require(), it will cause a fatal error and halt the execution of the script. If the file is not found by include(), a warning will be issued, but execution will continue.
Expression preceding the ? is evaluated, if it’s true, then the expression preceding the : is executed, otherwise, the expression following : is executed.
The session support can be turned on automatically at the site level, or manually in each PHP page script:
* Turning on session support automatically at the site level: Set session.auto_start = 1 in php.ini.
* Turning on session support manually in each page script: Call session_start() funtion.
