strange to me that a successful variable value assignment does not return

example:

$shiny = 1;
if($shiny = 0){
if($shiny = 0){
This does not compare anyting, it assigns 0 to $shiny
echo( $shiny ) // this will return 0
That's normal, you just assign 0 to it ;)

It looks to me like the value of an assignment is the value assigned, as

if($shiny = 0)
This line is the same as
if ((shiny = 0) == TRUE)
It's common error with PHP and C.
You could make use of this like
if ($fp = fopen($filename,'r'))
since this is the same as
if (($fp = fopen($filename,'r')) == TRUE)
code after this line is executed when fopen() success to
7 matches
