Question

我有一个非常复杂的数组，我想将它转换为PHP有效数组，这样我就可以遍历这些值。

JS数组：

$test = (       // Portraits
  {'image'=> 'http://farm8.staticflickr.com/7319/8993158058_f82968e61a_b.jpg', 'thumb'=> 'http://farm8.staticflickr.com/7319/8993158058_f82968e61a_t.jpg'},
  {'image'=> 'http://farm3.staticflickr.com/2891/8993155214_b8e091c625_b.jpg', 'thumb'=> 'http://farm3.staticflickr.com/2891/8993155214_b8e091c625_t.jpg'},
  {'image'=> 'http://farm8.staticflickr.com/7432/8993133146_d647438c55_b.jpg', 'thumb'=> 'http://farm8.staticflickr.com/7432/8993133146_d647438c55_t.jpg'});

修改

PHP循环：它应该是每个值的图像部分

  for ($i = 0;$i < $test.length;$i++){
    saveToDisk($test[$i]['image'],$i);
 }

以上是否正确？我怎样才能读懂数值？

Answer 1

您可以使用json_decode函数将json格式的字符串转换为PHP数组（如果您在没有第二个参数的情况下调用它，则使用对象，或者使用false）

$test = '[{"image":"http:\/\/farm8.staticflickr.com\/7319\/8993158058_f82968e61a_b.jpg","thumb":"http:\/\/farm8.staticflickr.com\/7319\/8993158058_f82968e61a_t.jpg"},{"image":"http:\/\/farm3.staticflickr.com\/2891\/8993155214_b8e091c625_b.jpg","thumb":"http:\/\/farm3.staticflickr.com\/2891\/8993155214_b8e091c625_t.jpg"},{"image":"http:\/\/farm8.staticflickr.com\/7432\/8993133146_d647438c55_b.jpg","thumb":"http:\/\/farm8.staticflickr.com\/7432\/8993133146_d647438c55_t.jpg"}]';

$array = json_decode($test, 1);

// Looping each inner array and printing image/thumb keys
foreach ($array as $arr) {
   echo $arr['image'].' - '.$arr['thumb'];
}

另外，为了将JavaScript对象转换为有效的JSON字符串，您应该使用JSON.strngify函数：

JSON.stringify(object); // <-- JavaScript function

您的“数组”代码看起来像PHP和Javascript语法之间的无效混合。它看起来应该更像：

$test = json_decode("[
  {'image'=> 'http://farm8.staticflickr.com/7319/8993158058_f82968e61a_b.jpg', 'thumb'=> 'http://farm8.staticflickr.com/7319/8993158058_f82968e61a_t.jpg'},
  {'image'=> 'http://farm3.staticflickr.com/2891/8993155214_b8e091c625_b.jpg', 'thumb'=> 'http://farm3.staticflickr.com/2891/8993155214_b8e091c625_t.jpg'},
  {'image'=> 'http://farm8.staticflickr.com/7432/8993133146_d647438c55_b.jpg', 'thumb'=> 'http://farm8.staticflickr.com/7432/8993133146_d647438c55_t.jpg'}]");

或者更好：

$test = [
  ['image'=> 'http://farm8.staticflickr.com/7319/8993158058_f82968e61a_b.jpg', 'thumb'=> 'http://farm8.staticflickr.com/7319/8993158058_f82968e61a_t.jpg'],
  ['image'=> 'http://farm3.staticflickr.com/2891/8993155214_b8e091c625_b.jpg', 'thumb'=> 'http://farm3.staticflickr.com/2891/8993155214_b8e091c625_t.jpg'],
  ['image'=> 'http://farm8.staticflickr.com/7432/8993133146_d647438c55_b.jpg', 'thumb'=> 'http://farm8.staticflickr.com/7432/8993133146_d647438c55_t.jpg']
];
