Hi,
I'm fairly new to PHP, having migrated from the Java / C# world.
I wrote some code similar to the following:
$success = true;
$success &= operation1();
$success &= operation2();
if ($success === true) {
operation3(); // depends on 1 and 2 being successful
}
This didn't work as expected. After a bit of digging I found:
* The &= operation isn't mentioned anywhere in the PHP documentation
* The &= function seems to work as expected, however the following is
observed...
$success = true;
$success &= true;
print $success == true; // outputs 1
print $sucesss === true; // no output
* The 'or' assignment operator |= causes no errors but doesn't work.
Can any PHP gurus explain why the &= operator works at all, and why
=== seems to fail afterwards?
Cheers,
Gavin.
