    What do you want to do?

    Just match, or match and replace!

    Hi

    If you just want to match.... (use 1 of these)

    <?

/* if match found execute if() */

if ( preg_match ( '!(<\!-- Instance(Begin|End)Editable( name="MainBody")? -->)!s', $str ) )
{
	echo 'match found';
}

/* if match not found execute if() */

if ( ! preg_match ( '!(<\!-- Instance(Begin|End)Editable( name="MainBody")? -->)!s', $str ) )
{
	echo 'match not found';
}

?>
    PHP:

    If you want the data beween the 2 tags then use str_ type functions....

    example...

    <?

$str = 'mmmmmmmmmmmmmmmmmmmmmm  
<!-- InstanceBeginEditable name="MainBody" -->
,,,,,,,,,,nnnnnnnnnnn
nnnnnnnnnn
jhhhhh54
766666
<!-- InstanceEndEditable -->
666666
66666666346';


$start = '<!-- InstanceBeginEditable name="MainBody" -->';
$stops = '<!-- InstanceEndEditable -->';


echo substr ( $str, ( $pos = ( strpos ( $str, $start ) + strlen ( $start ) ) ), ( strpos ( $str, $stops, $pos ) - $pos ) );


?>
    PHP:
