Equality question

I hope my question has a simple answer. Why am I getting a true result for the following:

("b" == 0)

PHP version 3.0.12

Thanks for your help,
Scott

I guess it doesn't know what 'b' is and deems it to be '0'
If you are testing a variable ($b) try this

<?
if (isset($b)) {
print("set");
}else {
print("not set");
}
?>

I use PHP4 so I hope this function works with PHP3

let me know if thats not what you were after.

Because you are comparing a string with a number. PHP casts the string to a number then does the compare.

Try this:

("b" == "0")

and you will get a false like you expected.

Also, try this:

("b" == (string)0)

should return a false, since we are now casting the 0 to a string instead of an int.

Thanks for your responses. I casted the 0 to a string and all was well.

Thanks again,
Scott
