PHP数组，具有值的新维度

我已经试着做了几个小时了，但我没有任何具体的想法。我希望达到如下所示的结果。该数组是从json文件派生的

我有：

[0] => Array(
    [Id] => scr_1 
    [Size] => 1920, 1080
)
[1] => Array(
    [Id] => scr_2 
    [Size] => 1280, 1024
)

我的目标是：

[0] => Array(
    [Id] => scr_1
    [Size] => Array( 
        [Width] => 1920 
        [Height] => 1080
    )
)
[1] => Array(
    [Id] => scr_
    [Size] => Array( 
        [Width] => 1280
        [Height] => 1024
    )
)

我该怎么做？

提前谢谢你

您需要将数组添加到

Size

键中的字符串中

$yourArray = array(
    array(
        "Id" => "scr_1",
        "Size" => array(
            "Width" => 1920,
            "Height" => 1080
        )
    ),
    array(
        "Id" => "scr_2",
        "Size" => array(
            "Width" => 1280,
            "Height" => 1024
        )
    )
);
$newArray = array();
foreach ($yourArray as $k => $res) {
    $newArray[$k] = array(
        "Id" => $res["Id"],
        "Size" => explode(",", $res["Size"])
    );
}

您需要在

Size

键中为字符串添加数组

$yourArray = array(
    array(
        "Id" => "scr_1",
        "Size" => array(
            "Width" => 1920,
            "Height" => 1080
        )
    ),
    array(
        "Id" => "scr_2",
        "Size" => array(
            "Width" => 1280,
            "Height" => 1024
        )
    )
);
$newArray = array();
foreach ($yourArray as $k => $res) {
    $newArray[$k] = array(
        "Id" => $res["Id"],
        "Size" => explode(",", $res["Size"])
    );
}

请尝试以下代码：

<?php

$array = array(
    array(
        "Id" => "scr_1",
        "Size" => "1920, 1080"
    ),
    array(
        "Id" => "scr_2",
        "Size" => "1280, 1024"
    )
);

$newArray = array();

foreach ($array as $k => $v) {
    $size = explode(', ', $v['Size']);
    $newArray[$k]= array('Id' => $v['Id'],  'Size' => array('Width' => $size[0], 'Height' => $size[1]));
}   

print_r($newArray);

尝试以下代码：

<?php

$array = array(
    array(
        "Id" => "scr_1",
        "Size" => "1920, 1080"
    ),
    array(
        "Id" => "scr_2",
        "Size" => "1280, 1024"
    )
);

$newArray = array();

foreach ($array as $k => $v) {
    $size = explode(', ', $v['Size']);
    $newArray[$k]= array('Id' => $v['Id'],  'Size' => array('Width' => $size[0], 'Height' => $size[1]));
}   

print_r($newArray);

试试这段代码

<?php
    $myarray[0]["Id"] = "scr_1";
    $myarray[0]["Size"]= "1920, 1080";
    $myarray[1]["Id"] = "scr_2";
    $myarray[1]["Size"]= "1920, 1080";
    foreach($myarray as $key =>$value){
        list($width, $height) = explode(", ",$value["Size"]);
        $myarray[$key]['Size'] = array("Width"=>$width, "Height" =>$height);
    }
    echo "<pre>";print_r($myarray);
    ?>


试试这段代码

<?php
    $myarray[0]["Id"] = "scr_1";
    $myarray[0]["Size"]= "1920, 1080";
    $myarray[1]["Id"] = "scr_2";
    $myarray[1]["Size"]= "1920, 1080";
    foreach($myarray as $key =>$value){
        list($width, $height) = explode(", ",$value["Size"]);
        $myarray[$key]['Size'] = array("Width"=>$width, "Height" =>$height);
    }
    echo "<pre>";print_r($myarray);
    ?>


$array=array（数组（'Id'=>'scr_1'，'Size'=>'1920，1080'）、数组（'Id'=>'scr_1'，'Size'=>'1920，1080'））；
foreach（$key=>$val的数组）
{
$size=explode（“，”，$val['size']）；
$new['Width']=$size[0]；
$new['height']=$size[1]；
$array[$key]['Size']=$new；
