Hi Master!
I used php5.2 to write a class for some needs, I was surperised to find the static variable worked in an abnormal way, so I need you help to test it!

--- test.php
<?php
class JavaBridgeLoader {
	private static $configedFlag = false;
	const jar_path = "jar/";
		
    public static function preConfig(){
    	var_dump(self::$configedFlag);
    	if(self::$configedFlag == false){
    		//exec('java -jar '. self::jar_path. '"JavaBridge.jar" SERVLET:8080');
    		
    		self::$configedFlag = true;
    	}
    	var_dump(self::$configedFlag);
    } 	
}
JavaBridgeLoader::preconfig();
?>


I expect for the result is "bool(false) bool(true) at the first time, And then: bool(true) bool(true) at the second time"

I am not a phper, I am a java liker and want to learn the php lanugage, I dont know why it can not performence like java performence, So I report this bug!

Thank you and hoping for you responsing...
And best Regards to you all!



Reproduce code:
---------------
<?php
class JavaBridgeLoader {
	private static $configedFlag = false;
	const jar_path = "jar/";
		
    public static function preConfig(){
    	var_dump(self::$configedFlag);
    	if(self::$configedFlag == false){
    		//exec('java -jar '. self::jar_path. '"JavaBridge.jar" SERVLET:8080');
    		
    		self::$configedFlag = true;
    	}
    	var_dump(self::$configedFlag);
    } 	
}
JavaBridgeLoader::preconfig();
?>

Expected result:
----------------
bool(false) bool(true) ---- the first time 

bool(true) bool(true)  ---- the second time

Actual result:
--------------
bool(false) bool(true) ---- the first time 

bool(false) bool(true)  ---- the second time
