Getting started with regular expressions

For many beginners, regular expressions seems to be hard to learn and use. In fact, they're far less hard than you may think. Before we dive deep inside regexp with useful and reusable codes, let's quickly see the basics:

Regular expressions syntax

PHP regular expression functions

Validate domain name

Verify if a string is a valid domain name.

$url = "http://tutarchive.com/";
if (preg_match('/^(http|https|ftp)://([A-Z0-9][A-Z0-9_-]*(?:.[A-Z0-9][A-Z0-9_-]*)+):?(d+)?/?/i', $url)) {
    echo "Your url is ok.";
} else {
    echo "Wrong url.";
}

Enlight a word from a text

This very useful regular expression find a specific word in a text, and enlight it. Extremely useful for search results.

$text = "Sample sentence from KomunitasWeb, regex has become popular in web programming. Now we learn regex. According to wikipedia, Regular expressions (abbreviated as regex or regexp, with plural forms regexes, regexps, or regexen) are written in a formal language that can be interpreted by a regular expression processor";
$text = preg_replace("/b(regex)b/i", '<span style="background:#5fc9f6">1</span>', $text);
echo $text;

Enlight search results in your WordPress blog

As I just said that the previous code snippet could be very handy on search results, here is a great way to implement it on a WordPress blog.
Open your search.php file and find the the_title() function. Replace it with the following:

echo $title;

Now, just before the modified line, add this code:

Save the search.php file and open style.css. Append the following line to it:

strong.search-excerpt { background: yellow; }

Get all images from a HTML document

If you ever widhed to be able to get all images form a webpage, this code is a must have for you. You should easily create an image downloader using the power of cURL.

$images = array();
preg_match_all('/(img|src)=("|')[^"'>]+/i', $data, $media);
unset($data);
$data=preg_replace('/(img|src)("|'|="|=')(.*)/i',"$3",$media[0]);
foreach($data as $url)
{
	$info = pathinfo($url);
	if (isset($info['extension']))
	{
		if (($info['extension'] == 'jpg') ||
		($info['extension'] == 'jpeg') ||
		($info['extension'] == 'gif') ||
		($info['extension'] == 'png'))
		array_push($images, $url);
	}
}

Remove repeated words (case insensitive)

Often repeating words while typing? This handy regexp will be very helpful.

$text = preg_replace("/s(w+s)1/i", "$1", $text);

Remove repeated punctuation

Same as above, but with punctuation. Goodbye repeated commas!

$text = preg_replace("/.+/i", ".", $text);

Matching a XML/HTML tag

This simple function takes two arguments: The first is the tag you'd like to match, and the second is the variable containing the XML or HTML. Once again, this can be very powerful used along with cURL.

function get_tag( $tag, $xml ) {
  $tag = preg_quote($tag);
  preg_match_all('{<'.$tag.'[^>]*>(.*?)</'.$tag.'>.'}',
                   $xml,
                   $matches,
                   PREG_PATTERN_ORDER);
 
  return $matches[1];
}

Matching an XHTML/XML tag with a certain attribute value

This function is very similar to the previous one, but it allow you to match a tag having a specific attribute. For example, you could easily match <div id="header">.

function get_tag( $attr, $value, $xml, $tag=null ) {
  if( is_null($tag) )
    $tag = '\w+';
  else
    $tag = preg_quote($tag);
 
  $attr = preg_quote($attr);
  $value = preg_quote($value);
 
  $tag_regex = "/<(".$tag.")[^>]*$attr\s*=\s*".
                "(['\"])$value\\2[^>]*>(.*?)<\/\\1>/"
 
  preg_match_all($tag_regex,
                 $xml,
                 $matches,
                 PREG_PATTERN_ORDER);
 
  return $matches[3];
}

Matching hexadecimal color values

Another interesting tool for web developers! It allows you to match/validate a hexadecimal color value.

$string = "#555555";
if (preg_match('/^#(?:(?:[a-fd]{3}){1,2})$/i', $string)) {
echo "example 6 successful.";
}

Find page title

This handy code snippet will find and print the text within the <title> and </title> tags of a html page.

$fp = fopen("http://tutarchive.com/blog","r");
while (!feof($fp) ){
    $page .= fgets($fp, 4096);
}
 
$titre = eregi("<title>(.*)</title>",$page,$regs);
echo $regs[1];
fclose($fp);

Parsing Apache logs

Most websites are running on the well-known Apache webserver. If your website does, what about using PHP and some regular expressions to parse Apache logs?

//Logs: Apache web server
//Successful hits to HTML files only.  Useful for counting the number of page views.
'^((?#client IP or domain name)S+)s+((?#basic authentication)S+s+S+)s+[((?#date and time)[^]]+)]s+"(?:GET|POST|HEAD) ((?#file)/[^ ?"]+?.html?)??((?#parameters)[^ ?"]+)? HTTP/[0-9.]+"s+(?#status code)200s+((?#bytes transferred)[-0-9]+)s+"((?#referrer)[^"]*)"s+"((?#user agent)[^"]*)"$'
 
//Logs: Apache web server
//404 errors only
'^((?#client IP or domain name)S+)s+((?#basic authentication)S+s+S+)s+[((?#date and time)[^]]+)]s+"(?:GET|POST|HEAD) ((?#file)[^ ?"]+)??((?#parameters)[^ ?"]+)? HTTP/[0-9.]+"s+(?#status code)404s+((?#bytes transferred)[-0-9]+)s+"((?#referrer)[^"]*)"s+"((?#user agent)[^"]*)"$'

Replacing double quotes by smart qutotes

If you're a typographer lover, you'll probably love this regexp, which allow you to replace normal double quotes by smart quotes. A regular expression of that kind is used by WordPress on contents.

preg_replace('B"b([^"x84x93x94rn]+)b"B', '?1?', $text);

Checking password complexity

This regular expression will tests if the input consists of 6 or more letters, digits, underscores and hyphens.
The input must contain at least one upper case letter, one lower case letter and one digit.

'A(?=[-_a-zA-Z0-9]*?[A-Z])(?=[-_a-zA-Z0-9]*?[a-z])(?=[-_a-zA-Z0-9]*?[0-9])[-_a-zA-Z0-9]{6,}z'

WordPress: Using regexp to retrieve images from post

As I know many of you are WordPress users, you'll probably enjoy that code which allow you to retrieve all images from post content and display it.
To use this code on your blog, simply paste the following code on one of your theme files.

 
post_content;
$szSearchPattern = '~<img alt="" />]* /&gt;~';
 
// Run preg_match_all to grab all the images and save the results in $aPics
preg_match_all( $szSearchPattern, $szPostContent, $aPics );
 
// Check to see if we have at least 1 image
$iNumberOfPics = count($aPics[0]);
 
if ( $iNumberOfPics &gt; 0 ) {
     // Now here you would do whatever you need to do with the images
     // For this example the images are just displayed
     for ( $i=0; $i &lt; $iNumberOfPics ; $i++ ) {           echo $aPics[0][$i];      }; }; endwhile; endif; ?&gt;

Generating automatic smileys

Another function used by WordPress, this one allow you to automatically replace a smiley symbol by an image.

$texte='A text with a smiley :-)';
echo str_replace(':-)','<img src="smileys/souriant.png">',$texte);
