RE: [PHP] '<?=' History / Info request

I had never touched short_open_tag in PHP.ini and <?=$var?> outputs me $var perfectly. So I guess who would turn it off would know why script doesn't work. However to be 100% compatible use: <?PHP echo $var?> Yes, it looks 'longer' but that's the price of portability. I am SURE at 195% that in this way it will always work, or PHP is not then PHP ...

It's pretty undocumented. Thanks, Philip -- be outside the box.
