Another way to say this? (!=='')

[doubledee]

Is there a better way to say this...

 

	if ($_POST['PaRes'] !== '')

 

Is this the same as saying

 

Not IsEmpty()

 

or

 

Not IsNull()

It really depends on EXACTLY what you are checking for. If you want to ensure the value is not an empty string, then the code you posted is appropriate. The empty() function returns true on several different values.

Be carefull with empty, since it can return a false positive if the string being checked contains a single zero:

<?php
$x = '0';
if (empty($x)) echo "$x is empty<br>\n";
else echo "$x is not empty<br>\n";
?>

The above code will print

0 is empty

Yeah, I read the manual.

 

Looks like I better leave the code As-Is.

 

Thanks,
