Question

Let say we’ve text with more than one url within, so i would like to extract that url and doing some changes then shows up the text.

Here is the code i’m using

<?PHP
$text = "This is text with links http://google.com and www.yahoo.com";

$text = ereg_replace( "www\.", "http://www.", $text );
$text = ereg_replace( "http://http://www\.", "http://www.", $text );
$text = ereg_replace( "https://http://www\.", "https://www.", $text );

$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";

if(preg_match($reg_exUrl, $text, $url)) {

$text = preg_replace($reg_exUrl, '<a href="'.$url[0].'" rel="nofollow">'.$url[0].'</a>', $text);
echo $text;

}else{

echo "NO URLS";

}
?>

The problem

// output source (repeat for first link)

This is text with links <a href="http://google.com" rel="nofollow">http://google.com</a> and <a href="http://google.com" rel="nofollow">http://google.com</a>

It depends on array so it only takes the first URL $url[0] so how can i apply for all links to be found within the text ~ Thanks

Answer 1

Change the next line

$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";

to

$reg_exUrl = "/((http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?)/";

and

$text = preg_replace($reg_exUrl, '<a href="'.$url[0].'" rel="nofollow">'.$url[0].'</a>', $text);

to

$text = preg_replace($reg_exUrl, '<a href="\1" rel="nofollow">\1</a>', $text);
