//方法一：

function foo(&$bar){

$bar.=" and something extra";

}

$str="This is a String,";

foo($str);

echo $str; //output:This is a String, and something extra

echo "<br>";

//方法二：

function foo1($bar){

$bar.=" and something extra";

}

$str="This is a String,";

foo1($str);

echo $str; //output:This is a String,

echo "<br>";

foo1(&$str);
