Yep thanks, I realized that when I googled "U modifier".
This is what I'm using in case anyone wants to know:
//first replaces any line breaks with a token
identifier since preg_replace doesn't work with multiply lines
$cleaned_content = str_ireplace("\n","<!--// New Line //-->",
$content);
//this creates our regular query sequence... perl-
stylezzz
$reg = '/<!--\/\/ Remove Begin \/\/-->(.+)<!--\/\/ Remove End \/\/--
>/U';
$cleaned_content = preg_replace($reg,"",$cleaned_content);
//now just put our line breaks back into place
$cleaned_content = str_ireplace("<!--// New Line //-->","\n",
$cleaned_content);
The above code will replace everything in my string (which I pulled
from an HTML file) with all the <!--// Remove Begin //--> tags and
<!--// Remove End //--> and anything in between them removed!
The U modifier solved my problem where It was making "abxxab" into ""
when it's supposed to replace everything between a and b instead of
making "abxxab" into "xx";
Thanks again!
