PHP-用PHP读取JS数组

Question

我有一个非常复杂的数组，我想将其转换为PHP有​​效数组，以便我可以遍历所有值。

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'});

编辑

PHP循环：应该包含每个值的图像部分

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

以上正确吗？ 我如何读取这些值？

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（如果您在不使用第二个参数的情况下调用它，则将其转换为对象，或者使用false代替）

$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'];
}

同样，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

您可以使用json_decode在PHP中读取解析

Answer 3

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']
