As a lazy user, I want to get alerted when website goes down.

Solution:

	$homepage = file_get_contents('http://,monitoring--domain.com/');
        if(strlen($homepage) > 0) {
                echo "Got response, no action";
        }else {
                echo "No response from server, send out email...";
                $to      = '[email protected]';
                $subject = 'Weak up, you website is down!';
                $message = 'Weak up, you website is down!';
                $headers = 'From: [email protected]' . "\r\n" .
                'Reply-To: [email protected]' . "\r\n" .
                'X-Mailer: PHP/' . phpversion();
                mail($to, $subject, $message, $headers);

Run Shell command using PHPShell in your shared host

Categories: PHP; Tagged with: PHP • PHPShell • Shell; @ June 23rd, 2012 13:19

PHP has a shell_exec command: “Execute command via shell and return the complete output as a string ” http://php.net/manual/en/function.shell-exec.php

And here is a project: http://phpshell.sourceforge.net/

PHP Shell

PHP Shell is a shell wrapped in a PHP script. It’s a tool you can use to execute arbitrary shell-commands or browse the filesystem on your remote webserver. This replaces, to a degree, a normal telnet connection, and to a lesser degree a SSH connection.

You use it for administration and maintenance of your website, which is often much easier to do if you can work directly on the server. For example, you could use PHP Shell to unpack and move big files around. All the normal command line programs like ps, free, du, df, etc… can be used.

Download and config phpShell,, and then upload to your server, then you can run shell!

PHP Utils: 复制/批量移除数组内元素

Categories: PHP; Tagged with: Array • PHP • 复制数组; @ September 9th, 2010 22:20

1. 将$source内的元素复制到$target数组内
2. 将$target数组内拥有与 $source相同key的元素移除.

	/** 
	 * 将指定Array内的元素复制到目标Array中, 如果具有相同key, 则会被覆盖.
	 **/
	public static function copyArrayItems($source, $target) {
		foreach($source as $sourceItemKey=>$sourceItemValue) {
			$target[$sourceItemKey] = $sourceItemValue;
		}
		return $target;
	}
	
	/**
	 * 移除$target数组中中带有 $source中元素相同key的元素.
	 * @param $source
	 * @param $target
	 * @return unknown_type
	 */
	public static function removeArrayItems($source, $target) {
		foreach($source as $sourceKey => $sourseValue) {
			unset($target[$sourseValue]);
		}
		return $target;
	}
