Small script to read xml files recursively from a specified directory. Return the results in array format. Same code is written in little different format to make it to work in PHP 4 and 5 versions.

PHP 4

<?php
	$dir_path = '.';
	$files = get_files($dir_path, '.xml', 'r');
	print_r($files); // return all xml files in array format.

	function get_files($dir_path = '.', $searchPattern = '', $searchOption = '') {

		$files = array();

		if (is_dir($dir_path)) {
			if ($handle = opendir($dir_path)) {
				$l_searchPattern = (!empty($searchPattern) && substr($searchPattern,0,1) == '*') ? '.' . substr($searchPattern,0,1) . preg_quote(substr($searchPattern,1)) : $searchPattern;
				while (($file = readdir($handle)) !== false) {
					if ($file == "." || $file == ".." ) continue;

					$complete_filepath = $dir_path .'/'. $file;

					if (is_dir($complete_filepath) && ($searchOption == 'recursive' || $searchOption == 'r')) {
						$files = array_merge($files, get_files($complete_filepath, $searchPattern, $searchOption));
						continue;
					}

					if (!is_dir($complete_filepath) && empty($l_searchPattern) || preg_match("/$l_searchPattern$/i", $file)) {
						array_push($files, $complete_filepath);
					}
				}
				closedir($handle);
			}
		}

		return $files;
	}
?>

PHP 5

<?php

	$dir_path = '.';

	$files = get_files($dir_path, '.xml', 'r');

	print_r($files);

	function get_files($dir_path = '.', $searchPattern = '', $searchOption = '') {

		$files = array();

		if (is_dir($dir_path)) {
			$scan_files = scandir($dir_path);

			$l_searchPattern = (!empty($searchPattern) && substr($searchPattern,0,1) == '*') ? '.' . substr($searchPattern,0,1) . preg_quote(substr($searchPattern,1)) : $searchPattern;
			foreach($scan_files as $file) {
				if ($file == "." || $file == ".." ) continue;

				$complete_filepath = $dir_path .'/'. $file;

				if (is_dir($complete_filepath) && ($searchOption == 'recursive' || $searchOption == 'r')) {
					$files = array_merge($files, get_files($complete_filepath, $searchPattern, $searchOption));
					continue;
				}

				if (!is_dir($complete_filepath) && empty($l_searchPattern) || preg_match("/$l_searchPattern$/i", $file)) {
					array_push($files, $complete_filepath);
				}
			}
		}

		return $files;
	}

I have used scandir function in PHP 5 version, which is easiest way to read directories and files from specific directory. To learn more about scandir function – http://php.net/manual/en/function.scandir.php.

In get_files function, there are three parameters
1. $dir_path – The path you want to read files
2. $searchPattern – By default it is empty, If you don’t pass any value, then it will return all files. If you want only xml files then pass “.xml” or “*.xml”
3. $searchOption – By default it is empty, If you pass empty it will return files from top directory only. To recursively get files based on searchPattern then pass “recursive” or “r”.

Thanks for reading

<?php
$text = 'This is a simple text to find http://www.google.com
and http://www.about.com urls from the text and make it as links
URLs will be dynamically formatted as links, this avoid editing each post or text
in large archives or database - http://www.largeresource.net/ ';
$text = preg_replace( "/(^|\s)((http|https|ftp):\/\/[^\s<]+)/i", '\\1<a href="\\2">\\2</a>', $text );
echo $text;
?>

The above code will find the urls in $text and make it as links dynamically. This code can be used in any part of code structure easily.

<?php
    $in = fopen("http://xyz.com/backup.tar.gz", "rb");
    $out = fopen("backup.tar.gz", "w+");
    echo pipe_streams($in, $out);

    function pipe_streams($in, $out)
    {
        $size = 0;
        while (!feof($in)) $size += fwrite($out,fread($in,8192));
        return $size;
    }
?>

Create a download.php in your destination server and change the filename to be downloaded and created.
It will avoid user’s bandwidth and time and it is the easiest way to copy the large backup files from one server to another server, while changing the hosting server.

Download the latest phpmailer source code and copy it into your server.
And use the below script to send mails using SMTP server.

require_once("phpmailer/class.phpmailer.php");
require_once("phpmailer/class.smtp.php");

function smtp_auth_mail($to, $subject, $message, $headers, $auth = true)
{
	$mail             = new PHPMailer();

	$body             = $message;

	$mail->IsSMTP(); // telling the class to use SMTP
	$mail->Host       = "localhost"; // SMTP server
	$mail->Port       = "465"; // SMTP port
	$mail->SMTPSecure = "ssl"; // SMTP secure

	$mail->From       = "admin@xyz.com";
	$mail->FromName   = "XYZ Admin";

	if ($auth)
	{
		$mail->SMTPAuth	  = true;

		$mail->Username	  = "admin@xyz.com"; // in some servers @ will be replaced with +
		$mail->Password	  = "xyz123";
	}

	$mail->Subject    = $subject;

	$body = str_ireplace("\n", "<br>", $body);

	$mail->MsgHTML($body);

	$mail->AddAddress($to);

	if(!$mail->Send()) {
		if (stripos($mail->ErrorInfo, 'Data not accepted') === false)
			echo "Mailer Error: " . $mail->ErrorInfo;
			return false;
	} else {
	  return true;
	}
}

smtp_auth_mail('xyz@gmail.com', 'Test mail', 'Test mail from XYZ', '');

Finally smtp_auth_mail function will return true after sending the mail successfully otherwise it will return false.

<?php

	function selfURL() {
		if(!isset($_SERVER['REQUEST_URI'])) {
			$serverrequri = $_SERVER['PHP_SELF'];
		}
		else {
			$serverrequri = $_SERVER['REQUEST_URI'];
		}
		$s = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : "";
		$protocol = substr(strtolower($_SERVER["SERVER_PROTOCOL"]), 0, strpos($_SERVER["SERVER_PROTOCOL"], '/')).$s;
		$port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]);
		return $protocol."://".$_SERVER['SERVER_NAME'].$port.$serverrequri;
	}
?>

You can get the complete URL by using the below code.

 <?php echo selfURL(); ?> 

Found this little snippet that does almost the same…

select name, create_date, modify_date from sys.objects where type='P' order by modify_date desc

To find stored procedures modified after specified date

select name, create_date, modify_date from sys.objects where type='P' and modify_date > '2010-05-26 12:10:44.810' order by modify_date desc

To find stored procedures modified in last 15 days

select name, create_date, modify_date from sys.objects where type='P' and datediff(day, modify_date, getdate()) <= 15 order by modify_date desc

<?php

$parseurl = parse_url($_GET["url"]);

$service_port = getservbyname('www', 'tcp');

$address = gethostbyname($parseurl["host"]);

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket < 0) {
    echo "socket_create() failed: reason: " . socket_strerror($socket) . "\n";
}

$result = socket_connect($socket, $address, $service_port);
if ($result < 0) {
    echo "socket_connect() failed.\nReason: ($result) " . socket_strerror($result) . "\n";
}

$in = "HEAD " . $parseurl["path"] . " HTTP/1.1\r\n";
$in .= "Host: " . $parseurl["host"] . "\r\n";
$in .= "Connection: Close\r\n\r\n";
$out = '';

socket_write($socket, $in, strlen($in));

if ($out = socket_read($socket, 2048)) {
    $response = explode("\n", $out);
    $response_status = explode(" ", $response[0]);
    $response_string = $response_status[1] . " " . $response_status[2];
    echo $response_string; // prints response code and status
}

socket_close($socket);
?>

The above php code, parse the querystring complete url, makes socket connection, pass the head method in headers and finally prints the response code and status.

Here is the example how to pass the complete url to above php code.

http.php?url=http://www.google.com/

	function delete_old_files($folder_name, $no_latest_files = 10)
	{
		$file_list = array();
		if ($handle = opendir($folder_name)) {
			while (false !== ($file = readdir($handle))) {
				if ($file != "." && $file != "..") {
					$file_list[filemtime($folder_name."/".$file)] = $folder_name."/".$file;
				}
			}
			closedir($handle);
		}

		krsort($file_list);

		$i = 0;
		foreach($file_list as $key => $value)
		{
			$i++;
			if ($i <= $no_latest_files) continue;
			unlink($value);
		}
	}

The above function will loop through the specified folder and add file with file modified time as key and filename as value.
Then it will sort the array based on key and finally it will leave x no. of latest files and delete remaining files in the specified directory.

<script type="text/javascript">

var currenttime = '<? echo date("F d, Y H:i:s", time())?>' //PHP method of getting server date

///////////Stop editting here/////////////////////////////////

var montharray= new Array("January","February","March","April","May","June", "July","August","September","October","November","December");
var serverdate=new Date(currenttime);

function padlength(what){
	var output=(what.toString().length==1)? "0"+what : what;
	return output;
}

function displaytime(){
	serverdate.setSeconds(serverdate.getSeconds()+1);
	var datestring=montharray[serverdate.getMonth()]+" "+padlength(serverdate.getDate())+", "+serverdate.getFullYear();
	var timestring = padlength(serverdate.getHours())+":"+padlength(serverdate.getMinutes())+ ":" + padlength(serverdate.getSeconds());
	document.getElementById("clock").innerHTML = datestring + " " + timestring;
}

setInterval("displaytime()", 1000);

</script>

  	function is_valid_image_url($image_url)
  	{
  		$size = getimagesize($image_url);
  		if(!is_array($size))
  		{
  			return false;
  		}

  		return true;
  	}

The above function will return true, if the image url is valid otherwise false.
