复制代码 代码如下:
<?php
$a = array(1,1,32,322,3433,array(32,232,23232));
$b = 1234;
$c = "alsdfl;asdf";
$d = 'a';
$e = fopen("slsl.txt", "r");
var_dump($a);
echo "<br>";
var_dump($b);
echo "<br>";
var_dump($c);
echo "<br>";
var_dump($d);
echo "<br>";
var_dump($e);
echo "<br>";
echo "<br>";
echo "<br>";
echo "<br>";
var_export($a);
echo "<br>";
var_export($b);
echo "<br>";
var_export($c);
echo "<br>";
var_export($d);
echo "<br>";
var_export($e);
echo "<br>";
echo "<br>";
echo "<br>";
echo "<br>";
print_r($a);
echo "<br>";
print_r($b);
echo "<br>";
print_r($c);
echo "<br>";
print_r($d);
echo "<br>";
print_r($e);
echo "<br>";
输出：

现在可以看到效果了，注意，最后一个不是我没有粘贴过来，而是他本来就没有显示什么东西。
