return跟exit的区别

return和exit的区别？
主要是放在php主体代码中，有什么用法上的细致区别？

<?php<br />
echo  "a";<br />
return ;<br />
echo  "b";<br />
?><br />

<?php<br />
echo  "a";<br />
exit ;<br />
echo  "b";<br />
?><br />

------解决方案--------------------
die()停止程序运行，输出内容
exit是停止程序运行，不输出内容
return 不运行后面代码


------解决方案--------------------
return 是返回值，也有终止程序的作用
------解决方案--------------------
return 返回调用
exit 退出程序
对你的示例：没有区别

function func($v) {<br />
  echo $v;<br />
  return; //改成 exit 再看看<br />
}<br />
<br />
func(123);<br />

  return; //改成 exit 再看看<br />
}<br />
<br />
func(123);<br />

没有变化吧，不都是输出123

估计老大的意思是这样

function func($v) {<br />
  echo $v;<br />
  return; //改成 exit 再看看<br />
}<br />
<br />
func(123);<br />
echo '456';

------解决方案--------------------
噢，漏了一个

function func($v) {<br />
  echo $v;<br />
  return; //改成 exit 再看看<br />
}<br />
func(123);<br />
func(123);

123123

function func($v) {<br>
  echo $v;<br>
  exit; <div class="clear">
                 
              
              
        
            </div>
