Will an If Statement Stop Checking if the first OR condition is met in PHP? -

i want try , make code efficient possible , ive read

if($process == true) 

will process faster calls function. i.e

if(count($total) == 100)  

so if had or inside if , first condition simple boolean check , turned out true second part of condition still checked anyway?

for example

$process = true; if($process == true || count($total) == 100) 

would count function still called though process true , enough make condition pass.

php has indeed mechanic named short-circuit: http://php.net/manual/en/language.operators.logical.php#example-140

if first operand of logical or true, second part isn't evaluated, , function isn't called.

since comparing variable boolean faster calling function in php, mechanic can optimize, never forget premature optimisation root of evil.
