This will get the text up to the first occurrence of the pattern:

$pattern_without_delimiters = "mypattern.*ends here";
$new_text = preg_replace("#^(.*?){$pattern_without_delimiters}#s", "$1", $text);

Open in new window


Update: removed preg_quote call because it would change .* to \.\*
You'll need to escape any # characters that you want to match in your pattern (with a backslash).
