Can PHP detect include?

paket · May 2nd, 2008, 08:54 AM

Is a PHP script able to detect if it's being included in another one or being called directly? Python has a neat little trick:

Code:

if __name__ == "__main__":

that allows it to tell if the module is being run directly or if it's being imported. I want to write a bit of PHP that assigned it's output to a variable if it's being included in another, but echos the output if it's being called directly.

thanks

You could just detect whether the variable you're assigning to exists.

Code:

$html = '';

include '/some/file.php';

In /some/file.php...

Code:

if (isset($html))
{
  $html .= '';
}
else
{
  echo $html;
}

Regards,
Rich

I'd use output buffering in the caller to do something similar. A bit of a different approach, but keeps the controller logic out of your view.

Include and make output part of your html output:

Code:

include 'the/file.php';

Include, but assign to a variable:

Code:

ob_start();
include 'the/file.php';
$html = ob_get_contents();
ob_end_clean();
