如何回显出多维数组的两个部分？

Question

The problem I am getting is when I loop through the multidimensional array, once I get to skills in the multidimensional array, it prints out: Andrew Wiley 30 Game Designer 72000 Array C++ Level Design Leadership

It's printing out both Array and C++ Level Design Leadership.

How do I remove the output of Array and replace it with the skills C++ Level Design Leadership without printing both?

$students = [
    Andrew => [
        fullName => Andrew Wiley,
        age => 30,
        jobTitle => Game Designer,
        Salary => 72000,
        skills => [C++, Level Design, Leadership]
    ]
];

foreach($students[Andrew] as $student) {
    echo $student . <br>;
    if($student == $students[Andrew][skills]) {
        foreach($students[Andrew][skills] as $skill) {
            echo $skill;
        }
    }
};

Answer 1

You can use a recursive function.

function printVariables($array,$level=1){
    foreach($array as $value){
        if(is_array($value)){
            $level++;
            printVariables($value,$level);
        }else{
            echo $level <= 2 ? "$value\n" : "$value ";
        }
    }
}

printVariables($students);

Or serialize it...

foreach($students as $student){
     echo json_encode($student,JSON_PRETTY_PRINT);
}

Answer 2

Update your foreach like so:

foreach($students['Andrew'] as $student) {
    echo $student . <br>;
      if($student === $students['Andrew']['skills'] 
        && is_array($students['Andrew']['skills'])
        && count($students['Andrew']['skills']) > 0) {
           echo implode(", ",$students['Andrew']['skills']);
        }
 }

Output:

C++, Level Design, Leadership

What this does:

• If statement checks if it is equal,
• Then checks if it is an array
• Then checks that the array is not empty
• Before finally joining up all the array elements in to a string and outputting that string with echo .

Also note the quotes around the array keys
