List contents of a directory

August 21st, 2005 by SubZane

A quick and dirty way to list the contents of a directory. You might want to add more properties to it for displaying only certain file types and so on. I might post that later on.

Show as plain text
PHP:
  1. function dirList($directory) {
  2.   $results = array();
  3.   $handler = opendir($directory);
  4.   while ($file = readdir($handler)) {
  5.     if ($file != '.' && $file != '..')
  6.       $results[] = $file;
  7.   }
  8.   closedir($handler);
  9.   return $results;
  10. }

And how to use it:

Show as plain text
PHP:
  1. $arr = dirList("./");
  2. for ($i=0; $i<count ($arr); $i++) {
  3.   echo '<a href="'.$arr[$i].'">'.$arr[$i].'</a><br />';
  4. }

Validating an email address

August 17th, 2005 by SubZane

Today I will present you with the devious process to validate an email address. It's basicly the same way as with the URL, just a different regular expression.

Show as plain text
PHP:
  1. function isValidEmail($email) {
  2.   if (!eregi("^([a-zA-Z0-9\._\-]+)@([a-zA-Z0-9\._\-]+)\\.([a-zA-Z]+)$", $email)) {
  3.     return false;
  4.   } else {
  5.     return true;
  6.   }
  7. }

Retreive age from dob

August 16th, 2005 by SubZane

This function retreives age from date of birth. Pass it your date of birth as an integer (19800820) and it will return the age.

Show as plain text
PHP:
  1. function DOB2Age($dob) {
  2.   $year = date('Y');
  3.   $month = date('m');
  4.   $day = date('d');
  5.    
  6.   $age = ($year - (substr($dob, 0, 4) + 1));
  7.    
  8.   if ($month == substr($dob, 4, 2)) {
  9.     if ($day>= substr($dob, 6, 2)) {
  10.       $age++;
  11.     }
  12.   } else if ($month> substr($dob, 4, 2)) {
  13.     $age++;
  14.   }
  15.   if ($age == date('Y')) {
  16.     $age = 0;
  17.   }
  18.   return $age;
  19. }

Simple photogallery script

August 15th, 2005 by SubZane

It's all done by simply showing the contents of a directory. I've sorted a gallery in 1 folder with 3 subfolders. The name of the folder is the name of the gallery and the 3 subfolders are called "small", "big" and "huge".

Validating URL

August 11th, 2005 by SubZane

I will continue to post handy scripts here in this new area called "Use the source". Since I'm not made of scripts I'm going to start by posting one script or function everyday and see how long I can keep up :wink:
Today it's a script to validate URL's. If the string is a valid URL i will return True, if it's not, False. Quite simple.

Show as plain text
PHP:
  1. function isValidURL($url) {
  2.   if (!eregi("^((ht|f)tp://)((([a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3}))|(([0-9]{1,3}\.){3}([0-9]{1,3})))((/|\?)[a-z0-9~#%&'_\+=:\?\.-]*)*)$", $url)) {
  3.     return false;
  4.   } else {
  5.     return true;
  6.   }
  7. }
