Question

我想在foreach循环中分配每组数组，以便在唯一变量中分配

我已经形成了一个数组

Array
(
    [0] => Array
        (
            [title] => Mobiles & Accessories
        )

[1] => Array
    (
        [title] => Mobile Accessories
    )

[2] => Array
    (
        [title] => Cables
    )

)

Array
(
    [0] => Array
        (
            [title] => Computers
        )
[1] => Array
    (
        [title] => TV & Video Accessories
    )

[2] => Array
    (
        [title] => Cables
    )

)

Array
(
    [0] => Array
        (
            [title] => Home Entertainment
        )

[1] => Array
    (
        [title] => Video Players & Accessories
    )

[2] => Array
    (
        [title] => Video Accessories
    )

[3] => Array
    (
        [title] => Cables
    )

)

我希望每个数组都在唯一变量中

喜欢

$a = (
    [0] => Array
        (
            [title] => Mobiles & Accessories
        )
[1] => Array
    (
        [title] => Mobile Accessories
    )

[2] => Array
    (
        [title] => Cables
    )

)

$b = Array
(
    [0] => Array
        (
            [title] => Computers
        )
[1] => Array
    (
        [title] => TV & Video Accessories
    )

[2] => Array
    (
        [title] => Cables
    )

)

$c = Array
(
    [0] => Array
        (
            [title] => Home Entertainment
        )
[1] => Array
    (
        [title] => Video Players & Accessories
    )

[2] => Array
    (
        [title] => Video Accessories
    )

[3] => Array
    (
        [title] => Cables
    )

)

您可能正在寻找“Variable variables”。

有时能够拥有变量变量名称很方便。也就是说，一个可以动态设置和使用的变量名。

<?php
// your arrays
$arrI = [
    ['title' => 'Mobiles & Accessories'],
    ['title' => 'Mobile Accessories'],
    ['title' => 'Cables']
];
$arrII = [
    ['title' => 'Computers'],
    ['title' => 'TV & Video Accessories'],
    ['title' => 'Cables']
];
$arrIII = [
    ['title' => 'Home Entertainment'],
    ['title' => 'Video Players & Accessories'],
    ['title' => 'Video Accessories'],
    ['title' => 'Cables']
];

// You may access the arrays through the following names
$names = array('a', 'b', 'c');

// The arrays
$arrays = array($arrI, $arrII, $arrIII);

// Now, create variables named after the $names array elements,
// and associate each one with the corresponding array in the $arrays by the defined order.
for($i = 0; $i<count($names); $i++)
    $$names[$i] = $arrays[$i];

// Now, you can access the arrays using their new names!
echo "<pre>";
print_r($a);
echo "<hr>";
print_r($b);
echo "<hr>";
print_r($c);
echo "</pre>";
?>
