I have that text:
$text = 'Some text... <a href="http://foo.bar/***">Read More</a>';
I need to remove this: <a href="http://foo.bar/***">Read More</a>.
*** is unknown word.
Just use strip_tags function
<?php
$text = 'Some text... <a href="http://foo.bar/***">Read More</a>';
$text =strip_tags($text);
?>
<? Your test string is quite simple
