Re: [PHP] Php and regex help or advice

HTML usually change very often. Especially properties.

A link can change from: <a href="/">Home</a>
to: <a class="something" href="/">Home</a>

So, your regex must avoid using the properties to match elements

So, I think this should be a better expresion

preg_match_all(
   '#<p[^>]*><font[^>]*>(.+)<br/?>(.+)<br/?>(.+)Critical Violations
Found:#imsU',
   $html, // <-- your variable with the text
   $match // <-- here PHP sets the matches
);

print_r( $match );  // <-- take a look at the results, loop over these are
quite easy

Also using # as delimiter leaves you the / for simpler use, avoiding an
extra backslash.
