I just spent a half hour narrowing down a bug in an application I’d fut some polishing touches on in PHP5. When it was moved onto the production server earlier, it came up with blank pages. I wasn’t on hand to check it out, so couldn’t help over the phone. I had to wait until I could get to a computer to debug it.

The end problem was in a line similar to the following:

$n=$db->query('select id from some_table')->numRows();

The above worked in every server I had available - except the one it was supposed to go on.

To get that code working in PHP4, you must break the object results down:

$n=$db->query('select id from some_table');
$n=$n->numRows();

It’s an annoyance - but at least it’s not a large thing to fix, and the lines that need changing can easily be found by grepping for numRows().
