如何foreach和里面是其他foreach？

Question

我想显示用户名和每个用户的技能。用户显示正常但技能不工作如何解决？

index.php

<?php

$jsondata = file_get_contents("data.json");
$json = json_decode($jsondata, true);
$output = "";

foreach ( $json['UserData'] as $display ) {
  $output .="<p>" .$display['fname']. "</p> 

            </br>

            <h6>Skills :</h6>";

                foreach ( $json['skills'] as $value ) {

                    $output .="   <p>".$value."</p> </br>

                    ";

                }
}



echo $output;

?>

data.json

{
    "UserData": [

    {
        "id": "name",
        "fname": "Joey",
        "lname": "Tulang",
        "age": "29",
        "gender": "Male",
        "skills": [ "HTML", "CSS", "JavaScript" ],
        "image": [ "html.jpg", "css.jpg", "js.jpg" ]
    },
    {
        "id": "2",
        "fname": "Angelica",
        "lname": "Balce",
        "age": "20",
        "gender": "Female",
        "skills": ["C++", "Python", "PHP"],
        "image": [ "c++.jpg", "python.jpg", "php.jpg" ]
    },
    {
        "id": "3",
        "fname": "Mj",
        "lname": "King",
        "age": "21",
        "gender": "male",
        "skills": [ "Photoshop", "Figma", "Corel Draw"],
        "image": [ "photoshop.jpg", "figma.jpg", "cdraw.jpg" ]

Answer 1

您想改用foreach ( $display['skills'] as $value ) {。
