Question

我有这种类型的数组

   Array
(
    [0] => Samy Jeremiah,55
    [1] => Nelson Owen,93
    [2] => McMaster Ashlie,88
    [3] => Marsh Harlow,97
    [4] => Macfarquhar Aiden,95
    [5] => Lowe Sophie,91
);

我需要将此数组转换为以下类型的json

data: [     
        ['Samy Jeremiah',55 ],      
        ['Nelson Owen',93 ],    
        ['McMaster Ashlie',88 ] , 
        ['Marsh Harlow',97 ] ,  
        ['Macfarquhar Aiden',95 ],  
        ['Lowe Sophie',91 ]   
     ]

Answer 1

试试这个

<?php
    $yourArray = array(
        '0' => 'Samy Jeremiah,55', 
        '1' => 'Nelson Owen,93', 
        '2' => 'McMaster Ashlie,88', 
        '3' => 'Marsh Harlow,97', 
        '4' => 'Macfarquhar Aiden,95', 
        '5' => 'Lowe Sophie,91', 
    );

    #Check output 01
    //print_r($yourArray);

    foreach ($yourArray as $value) {                
        $explodeValue = explode( ',', $value );    
        $newName []= array($explodeValue[0] => $explodeValue[1]);
    }
    #Check output 02
    //print_r($newName);

    #Check output 03
    echo(json_encode($newName));
?>

输出01

Array ( 
    [0] => Samy Jeremiah,55 
    [1] => Nelson Owen,93 
    [2] => McMaster Ashlie,88 
    [3] => Marsh Harlow,97 
    [4] => Macfarquhar Aiden,95 
    [5] => Lowe Sophie,91 
)

输出02

Array ( 
    [0] => Array ( [Samy Jeremiah] => 55 ) 
    [1] => Array ( [Nelson Owen] => 93 ) 
    [2] => Array ( [McMaster Ashlie] => 88 ) 
    [3] => Array ( [Marsh Harlow] => 97 ) 
    [4] => Array ( [Macfarquhar Aiden] => 95 ) 
    [5] => Array ( [Lowe Sophie] => 91 ) 
)

输出03

[
    {"Samy Jeremiah":"55"},
    {"Nelson Owen":"93"},
    {"McMaster Ashlie":"88"},
    {"Marsh Harlow":"97"},
    {"Macfarquhar Aiden":"95"},
    {"Lowe Sophie":"91"}
]

Answer 2

您想要的结果是一个数组数组。您必须将数组的每个条目拆分为2个实体，并将它们作为数组推送到新数组中，然后将json_encode（）推送到新数组中。

这个php-snippet只有在你的输入是一个字符串数组时才有效，它包含每个逗号作为name和int-value之间的分隔符：

$arr2 = array();
foreach($arr1 as $e) {
  list($name, $val) = explode(',', $e);
  $arr2[] = array($name, (int)$val);
}
echo json_encode($arr2);

Answer 3

使用以下代码

$data = array('Samy Jeremiah,55', 'Nelson Owen,93', 'McMaster Ashlie,88', 'Marsh Harlow,97', 'Macfarquhar Aiden,95', 'Lowe Sophie,91');
    $res = array();
    foreach($data as $e) {
      $list = explode(',', $e);
      $res[] = array($list[0], $list[1]);
    }
    echo json_encode(['data'=>$arr2]);

<强>输出

{"data":[
         ["Samy Jeremiah",55],
         ["Nelson Owen",93],
         ["McMaster Ashlie",88],
         ["Marsh Harlow",97],
         ["Macfarquhar Aiden",95],
         ["Lowe Sophie",91]
        ]
}

Answer 4

使用json_encode，您可以实现您想要的效果。

假设您的数组名称为$arr，请立即应用json_encode。

echo json_encode(array('data'=>$arr)); //your json will be print here

实时示例：

$arr = array('Samy Jeremiah,55', 'Nelson Owen,93', 'McMaster Ashlie,88', 'Marsh Harlow,97', 'Macfarquhar Aiden,95', 'Lowe Sophie,91');
$new_arr = array();
foreach($arr as $k => $val){
    $na = explode(",", $val);
    $na[0] = "'".$na[0]."'";
    $value = implode(",", $na);
    $new_arr[$k] = $value;
}

echo json_encode(array("data" => $new_arr));
