I have : 

<a href="http://abc.com">Title</a>

And :

<a href="http://xyz.com">Title</a>

I want to replace link to text “Title”, but only from http://abc.com. But I don’t know how ( I tried Google ), can you explain for me. I’m not good in PHP.

Thanks in advance.

    Not sure I really understand what you’re asking, but if you :

    • Have a string that contains some HTML
    • and want to replace all links to abc.com by some text

    Then, a good solution (better than regular expressions, should I say !) would be to use the DOM-related classes — especially, you can take a look at the DOMDocument class, and its loadHTML method.

    For example, considering that the HTML portion is declared in a variable : 

    $html = <<<HTML
<p>some text</p>
<a href="http://abc.com">Title</a>
<p>some more text</p>
<a href="http://xyz.com">Title</a>
<p>and some again</p>
HTML;

    You could then use something like this :

    $dom = new DOMDocument();
$dom->loadHTML($html);
$tags = $dom->getElementsByTagName('a');
for ($i = $tags->length - 1 ; $i > -1 ; $i--) {
    $tag = $tags->item($i);
    if ($tag->getAttribute('href') == 'http://abc.com') {
        $replacement = $dom->createTextNode($tag->nodeValue);
        $tag->parentNode->replaceChild($replacement, $tag);
    }
}
echo $dom->saveHTML();

    And this would get you the following portion of HTML, as output :

    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html><body>
<p>some text</p>
Title
<p>some more text</p>
<a href="http://xyz.com">Title</a>
<p>and some again</p>
</body></html>

    Note that the whole <a href="http://abc.com">Title</a> portion has been replaced by the text it contained.

    If you want some other text instead, just use it where I used $tag->nodeValue, which is the current content of the node that’s being removed.

    Unfortunately, yes, this generates a full HTML document, including the doctype declaration, <html> and <body> tags, …
