  … Because there will be times in which you may want to include the contents of a php file into a variable.

  	function get_include_contents($filename) {
  
  	    if (is_file($filename)) {
  	        ob_start();
  	        include $filename;
  	        $contents = ob_get_contents();
  	        ob_end_clean();
  	        return $contents;
  	    }
  	    return false;
  	}
  

  I have edited my post to answer dave’s comment below.

  By looking at this funciton you may think it’s just a substitute of file_get_contents().
  The difference is that file_get_contents will return literaly the contents of the file, as opposed to get_include_contents that will actually run the code,
  and because we are turning on output buffering, we can get the output of the script and store it in a string. For example if we have the php file ‘example.php’:

  
  	echo 'The gamma laser toxic spill gave me powers';
  

  file_get_contents will produce the following result:

  
  	$string = file_get_contents('example.php');
  
  	echo $string;
  	// will output: echo 'The gamma laser toxic spill gave me powers';
  

  If we use get_include_contents() instead, it will produce the following result:

  
  	$string = get_include_contents('example.php');
  
  	echo $string;
  	// will output: The gamma laser toxic spill gave me powers
  

  If you are still thinking why would I want to do this, I will give you a real life example to ilustrate:

  Lets assume that you have the following email template in a file template.php:

  
  echo  'Dear Mr. ' . $params['name'] . ',';
  echo  'All your ' . $params['item'] . ' are belong to us!';
  

  The function could then be extended to accept some paramaters that the template will need to have on scope:

  	function get_include_contents($filename, $params) {
  
  	    if (is_file($filename)) {
  	        ob_start();
  	        include $filename;
  	        $contents = ob_get_contents();
  	        ob_end_clean();
  	        return $contents;
  	    }
  	    return false;
  	}
  

  After that we can send an email using template.php like this:

  
  	$html_email = get_include_contents(
  							   'example.php'
  							   array(
  								   'name'  =>; 'Satan',
  							           'item'  => 'Snakes'
  								  )
  							);
  
  	mail('someemail@blah.com', 'Subject', $html_email);	
  

  The recipient of the email will have a message in his inbox saying:

  
  Dear Mr. Satan,
  All your snakes are belong to us!

  Do you need to use PEAR, but you are behind a proxy that requires authentication?
  Use this command to set the correct values:

  pear config-set http_proxy http://username:password@proxyhost:port

  One more way to slugify texts in php, without the need of the iconv() function:

      public static function slugify($text) {
  		$text = trim($text);
  		$text = str_replace(".", "", $text);
  		$text = self::removeAccents($text);
  		// replace non letter or digits by -
  		$text = preg_replace('~[^\\pL\d]+~u', '-', $text);
  		// trim
  		$text = trim($text, '-');
  		// lowercase
  		$text = strtolower($text);
  		// remove unwanted characters
  		$text = preg_replace('~[^-\w]+~', '', $text);
  		return $text;
  
  	}
  
  	public static function removeAccents($text) {
  		$text = htmlentities(utf8_decode($text));
  		$remove = array("&", "acute", "grave", "circ", "tilde", "uml");
  		$text = str_replace($remove, "", $text);
  		return $text;
  	}
  

  Put it inside an Utils class, and use it like

  $slug = Utils::slugify("nothingisclear is awesome");

  I really don’t remember if i’ve written this or took it from someone on the web (if you recognize it, please let me know, or just know that i didn’t want to steal it :) ).

  Anyway today i was into slugs and i surprisingly found a php simple-and-working static method for converting strings into slugs and i felt like sharing it:

  /**
   * PHP "iconv" REQUIRED !!!
   * @param object $string
   * @param object $space [optional]
   * @return
   */
  
  public static function convertStringIntoSlug($string,$space="-") {  
  
  	if (function_exists('iconv')) {
          $string = @iconv('UTF-8', 'ASCII//TRANSLIT', $string);
      }  
  
      $string = strtolower(preg_replace("/[^a-zA-Z0-9 -]/","", $string));
      $string = str_replace(" ", $space, $string);
  
      return $string;
  
  }
  

  here i’ve already wrote about a good jquery alternative (written by Leo Caseiro) for doing this
