类外边的独立的自定义函数和类中静态方法有啥区别啊?
<br /><br />function test(){<br /> ………<br /> return $result; <br />}<br /><br />function test1(){<br /> ………<br /> return $result; <br />}<br /><br />……<br /><br />function testN(){<br /> ………<br /> return $result; <br />}<br /><br /><br />class funs{<br /> static function test(){<br /> ………<br /> return $result; <br /> }<br /> static function test1(){<br /> ………<br /> return $result; <br /> }<br /> ……<br /> static function testN(){<br /> ………<br /> return $result; <br /> }<br />}<br /><br /><br />$a = test();<br />$b = funs::test()<br /><br />……<br /><br />

写在类外边的单独的函数和写在类里边的静态的函数有啥区别?类外边的函数是静态的吗?也像教程中所说的静态的方法节约内存么?它们如果非要比比效率,哪个高啊?
把常用的函数写在类里定义为静态方法有好处么?
我是新手,请老手给予正确的指点!
