本文实例讲述了php传值赋值和传地址赋值用法。分享给大家供大家参考。具体如下:

<&#63;php
$name = 'Simon'; //对变量$name进行赋值(传值赋值)
$name_b = $name; //对变量$name_b进行赋值(传值赋值)
$addr = &$name; //对变量$addr进行赋值(传地址赋值)
$name = "Elaine"; //改变$name的值
echo $name; //输出$name,会发现$name的值发生了变化
echo $name_b; //输出$name_b,会发现$name_b的值没有发生变化
echo $addr; //输出$addr,会发现$addr的值发生了变化
$addr = "Helen"; //改变$addr的值
echo $name; //输出$name,会发现$name的值发生了变化
echo $addr; //输出$addr,会发现$addr的值发生了变化
