This question already has an answer here:
I have a big confusion over equal to operators(==.===), below I mentioned php code where checking condition that string "all" equal to numeric 0. But it returns true at double equal to ("all"==0)
, but not with others:
<?php
var_dump("all"==0);
var_dump("all"=="0");
var_dump("all"==="0");
var_dump("all"===0);
?>
Output:
bool(true)
bool(false)
bool(false)
bool(false)
for all the condition the answer should be false. but why "all"==0 is true. can anyone explain?
