Question

CURRENT ARRAY：

stdClass Object (
[name1] => Someting very useful
[text1] => Description of something useful
[url1] => link.to/useful
[name2] => Someting very useful2
[text2] => Description of something useful2
[url2] => link.to/useful2
[name3] => Someting very useful3
[text3] => Description of something useful3
[url3] => link.to/useful3
)

我需要： 创建多维数组，其中诸如name1，text1，url1（等等）的键将被放入自己的数组中。怎么做到这一点？

Answer 1

我想你想要：

$array = array_chunk((array)$object, $chunkSize = 3, $preserveKeys = true);

（$object是您上面的对象）

这会将您的对象转换为数组，并将其拆分为每个包含3个元素的较小数组

Answer 2

好;

$array = (array) $object;

Answer 3

即使你没有一致的输入，这也是非常通用的，比如每个孩子只有三个属性。此外，对象中的属性不必具有任何特定顺序。

//$obj is the object you have in the question
$objects = array();
foreach($obj as $key => $val) {
    $result = preg_match('%([a-zA-Z]+)([0-9]+)%', $key,$matches);
    $new_key = $matches[2];
    $property = $matches[1];
    if(!isset($objects[$new_key])) {
        $objects[$new_key] = array();
    }
    $objects[$new_key][$property] = $val;
}

Answer 4

$array = array();
$c = count($object) / 3;
(Array) $object;

for($i = 1; $i <= $c; $i++){

    $array[$i]['name' + $i] = $object['name' + $i];
    $array[$i]['text' + $i] = $object['text' + $i];
    $array[$i]['url' + $i] = $object['url' + $i];

}
