Question

我刚刚编写了一个抓取脚本，它可以工作。现在我得到这个输出：

Array
(
    [0] => Array
        (
            [0] => example stuff
            [1] => example stuff
            [2] => example stuff
            [3] => example stuff
        )

    )

        [0] => l
        [1] => l
        [2] => l
        [3] => l

    )

[5] => Array

        [3] => e

    )

    )

[8] => Array
    (
        [0] => f
        [1] => f
        [2] => f
        [3] => f

    )

）

现在我想要一个简单的foreach，每个$matches[1][0]，$matches[2][0]和$matches[3][0]都会返回给我。

我一直试图让这个好几个小时，但没有运气。有人能帮助我吗？

Answer 1

$result = array();
foreach ($matches as $match) {
    $result[] = array(
        $match[1],
        $match[2],
        $match[3],
    );
    // or unset($match[0]); if you don't need the original array anymore
    // or array_splice($match, 0, 1); if you also want to rearrange the keys
}

Answer 2

foreach($matches as $match){

    // $match[0] is what you need

}

如果要将结果包装在新数组中，可以将原始数组缩减为：

$newArray = array_reduce($matches, function(&$result, $match){

  $result[] = $match[0];

});

Answer 3

这是你想要的吗？

for ($i = 0; $i < count($matches); $i++)
{
    print $matches[$i][0];
}

Answer 4

foreach ($matches as $j => $match) {
   foreach ($match as $i => $mi) {
       if ($i != 0) unset($matches[$j][$i]);
   }
}

Answer 5

如果你只想要前三个：

$newArray = array(
    $matches[1][0],
    $matches[2][0],
    $matches[3][0]
);

结果：

    Array
    (
        [0] => /spellen/thumbs/a/aladdinwildride_6524.jpg
        [1] => spel Alladin Wide Rit
        [2] => /spellen/cartoons/2096/alladin-wide-rit.html
    )

php数组多维
