PHP implements auolink that converts URLs in text into links

Reprint: http://www.jb51.net/article/52916.htm

In fact, I introduced how to use PHP code in the article "Converting URL addresses in text into JavaScript and PHP custom functions for clickable links" To implement the method of converting a URL address into a link, today I will introduce to you a more concise version. Let’s take a look at the PHP source code first:

/**

* Author: SeeDZ

* From: http://code.seebz.net/p/autolink-php/

**/

function autolink($str, $attributes = array()) {

$attrs = '';

foreach ($attributes as $attribute=>$value) {

$attrs .= " {$attribute}="{$value}"";

}

$str = ' '.$str;

$str = preg_replace('`([^"='>])((http|https|ftp|ftps)://[^s< ] +[^s<.)])`i', '$1$2', $str);

$str = substr($str, 1);

return $str;

}

How about it, it’s very concise! Take a look at the API documentation of the function:

Syntax

string autolink ( string $str [ , array $attributes = array() ] )

Parameter introduction

str - required (String type data). The text that needs to be queried and replaced
attributes - optional (Array type data) to replace some optional parameters. .

Return value

Returns the replaced text.

autolink() is also very convenient to use. We can only pass one parameter, which is the required character text. For example:

$str = 'A link : http://example.com/?param=value#anchor.';

$str = autolink($str);

echo $str; // A link : http://example.com/?param=value#anchor .

?>

In addition, we can also set some additional link parameters, so that the generated link can be opened in a new window, or we do not want to search the

index

engineindexreplaced link. For example:

$str = 'http://example.com/';

$str = autolink($str, array("target"=>"_blank","rel"= >"nofollow"));

echo $str; // http://example. com/

?>

The above introduces the PHP implementation of auolink that converts URLs in text into links, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
