Can someone here find a page that explains the IF statement except for php.net because I found out lurking with code that the following works great:
if($_POST['something'] | $_POST['else'] == 1)
Before this I have posted this code:
if($_POST['something'] == 1 || $_POST['else'] == 1)
I have double checked that the function does what it is supposed to.
Where is a book / manual that explains this use of the if function?
