The (very usefull) function to parse apart HTML and eval the php embeded, is not 100% fullproof.
With a small modification (!== instead of !=) it is 100% fullproof:
function evalHTML ( $string ) {
$pos = 0;
/* Loop through to find the php code in html... */
while ( ($pos = strpos( $string, '<?' )) !== FALSE ) {
/* Find the end of the php code.. */
$pos2 = strpos( $string, '?>', $pos + 2);
echo "pos2= ".$pos2."<hr>\n";
/* FIX: Eval outputs directly to the buffer. Catch / Clean it */
ob_start();
eval( substr( $string, $pos + 2, $pos2 - $pos - 2) );
$value = ob_get_contents();
ob_end_clean();
/* Grab that chunk! */
$string = substr( $string, 0, $pos ) . $value . substr( $string,
$pos2 + 2);
}
return $string;
}
