I am completely a new to PHP. I am just in beginner level. So when i was going through the concept of Keywords global,local and static. there was an example specified to make us understand for static key word. "sometimes we want a local variable NOT to be deleted. We need it for a further job" which means the value when defined as static will no change right! below is the example i have seen .
my question is how is x getting incremented if it is defined as static. can some one explain me. again if i am wrong please correct me as i really dont know any in PHP. I am beginer.

Hi,
I am completely a new to PHP. I am just in beginner level. So when i was going through the concept of Keywords global,local and static. there was an example specified to make us understand for static key word. "sometimes we want a local variable NOT to be deleted. We need it for a further job" which means the value when defined as static will no change right! below is the example i have seen .
Code:
<?php
function myTest() {
static $x = 0;
echo $x;
$x++;
}
myTest();
myTest();
myTest();
?>
Result:
0
1
2
my question is how is x getting incremented if it is defined as static. can some one explain me. again if i am wrong please correct me as i really dont know any in PHP. I am beginer.
Thank you!
