Have you ever try this :

if ("hello" == 0) echo "what's going on ?";

the condition is true because it will try to convert "hello" in an integer which is 0, so 0==0, so it's true

but if you try

if ("123" == 0) echo "what's going on ?";

this is false because "123" --> 123 and obviously 123 != 0

merci pour l'explication.

we need to be careful with the 0, in our script:

if (0 == "hello") -> TRUE !
if (1 == "hello") -> FALSE

bye.

You need to add an extra = sign.

Eg:

if ("hello" === 0)
{
echo "what's going on";
}
