将print_r()生成的数据转换回php代码

string var_export ( mixed $expression [, bool $return = false ] )

$data = array(
    'name' => 'John',
    'age' => 25,
    'email' => 'john@example.com'
);

// 使用print_r()打印数组
print_r($data);

// 使用var_export()将print_r()生成的数据转换回PHP代码
$code = var_export($data, true);

// 输出转换后的PHP代码
echo $code;

Array
(
    [name] => John
    [age] => 25
    [email] => john@example.com
)
array (
  'name' => 'John',
  'age' => 25,
