Remove everything BEFORE and AFTER certain chars in a string

Good day,

I want to remove everything before and after a certain character sequence in a string.

E.g:

$string = 'TESTING<html>This is a string</html>ANOTHER TEST!!';

I want everything before <html> and after </html> to be removed, so that the string looks like this when I write it to a database:

<html>This is a string</html>

Important thing here is that <html> and </html> keep existing in the string.

Anyone got an idea?

Along with the posted answers, you can also use strstr() function to get the text before and after like;

$newstring = '<html>' . strstr($string, '<html>');
$newstring = strstr($newstring, '</html>', true) . '</html>';

Try something like this:

// vars
$string = ' This is text before <html> and this is the text in between </html> And after there is some more text.. ';
$first = '<html>';
$last = '</html>';
// job
$start = stripos($string, $first); // first occurrence position 
$length = strripos($string, $last); // last occurrence position 
$newString = substr($string, $start, ($length-$start+strlen($last))); 
// output
var_dump($string,$start,$length,$newString);

Can be done with a regular expression:

$str = 'TESTING<html>This is a string</html>ANOTHER TEST!!';
preg_match_all('/(<html>.*<\/html>)/', $str, $matches);
print_r($matches[1][0]);

For a multiline string, you have to add the modifier "m":

$str = 'TESTING<html>This is a string</html>ANOTHER TEST!!';
preg_match_all('/(<html>.*<\/html>)/m', $str, $matches);
print_r($matches[1][0]);
