[PHP] URL Regular Expression

[Sidoh]

Inefficient.

Code: [Select]


$message = preg_replace("<REGULAR EXPRESSION THAT WORKS>", '<a href="\1">\1</a>', $message);


SO PWNS that.  I just need a working regular expression.  I'm shocked none of you have worked with them.  O_o

Well, not so much you, Joe.  You're a VB person =p

<?
  echo findurl("ftp://www.test.org str1 http://www.test.com str2 ftp://www.x86labs.org str3");

  function findurl($data) {
    $ret = "";
    $words = explode(" ", $data);
    foreach($words as $word) {
      if (substr($word, 0, 7) == "http://") {
        $ret = $ret . '<a href="' . $word . '">' . $word . "</a> ";
      }elseif (substr($word, 0, 6) == "ftp://") {
        $ret = $ret . '<a href="' . $word . '">' . $word . "</a> ";
      }else{
        $ret = $ret . $word . " ";
      }
    }
    return $ret;
  }
?>

Sidoh, do you always mess up your code?

Code: [Select]

<?php

[b]$seach = array();[/b]
$replace = array();

[b]$search[] = [/b]

"^(((ht|f)tp(s?))\:\/\/)(www.|[a-zA-Z].)[a-zA-Z0-9\-\.]+\.([a-z])(\:[0-9]+)*((\/?))(([a-zA-Z0-9\.

\,\;\?\'\\\=\/\_\-\#]+)?)^";
$replace[] = '<a href="\0" target="_blank">\0</a>';

$string = "Hello. This is a test string. http://www.google.com <br /><br />I hope this 

serves as proof that regular expressions > all. http://sidoh.no-ip.org/reg-ex.php FTW. <br /><br

$string = preg_replace($search, $replace, $string);

Know that [ php] is a syntax highlighted tag, so don't expect the bold tag will work in the future.

Additionally, since PHP contains the ability to define variables implicitly, I didn't mess up my code.  It works fine, there's just memory allocated for an array that isn't used.
