本文为大家讲解的是PHP中删除变量时unset()和null的区别分析，感兴趣的同学参考下。

当程序里不再使用某些大体积的变量时（如：数组或对象），我们有必要删除它们
第一种方法：$varname=null
第二种方法：unset($varname)
这两种方法都可以删除变量，但结果有些许的差别。
代码：

<?php

$a = array(

'a' => 'a',

'b' => 'b'

);

$b = array(

'a' => 'a',

'b' => 'b'

);

$a['b'] = null;

unset($b['b']);

print('<pre>');

print_r($a);

print('<br />');

print_r($b);

print('</pre>');

?>

结果：

Array

(

[a] => a

[b] =>

)

Array

(

[a] => a

)
