Why does PHP consider 0 to be equal to a string?

Question

I have the following piece of code:

$item[\'price\'] = 0;
/* Code to get item information goes in here */
if($item[\'price\'] == \'e\') {
    $item[\'price\'         


        

Answer 1

The == operator will try to match values even if they are of different types. For instance:

'0' == 0 will be true

If you need type comparison as well, use the === operator:

'0' === 0 will be false
