Just to add, there's also the var_exportfunction. I've found this useful for certain situations. From the manual:
补充一点，还有这个var_export功能。我发现这对某些情况很有用。从手册：
var_export — Outputs or returns a parsable string representation of a variable
var_export — 输出或返回变量的可解析字符串表示
Example:
例子：
<?php
$a = array (1, 2, array ("a", "b", "c"));
var_export($a);
?>
Returns this output (which can then be converted back to an array using eval()):
返回此输出（然后可以使用eval()将其转换回数组）：
array (
0 => 1,
1 => 2,
2 =>
array (
0 => 'a',
1 => 'b',
2 => 'c',
),
)

function makestring($array)
{
$outval = '';
foreach($array as $key=>$value)
{
if(is_array($value))
{
$outval .= makestring($value);
}
else
{
$outval .= $value;
}
}
return $outval;
}
