In PHP, if you want to return the entire array, you can use the keyword return to return the entire array. The following are two methods of returning an array:
Method one: Return the entire array by directly using the return keyword
function get_students() {
$students = array(
array("name" => "张三", "age" => 22),
array("name" => "李四", "age" => 23),
array("name" => "王五", "age" => 24)
);
return $students;
}
$all_students = get_students();
print_r($all_students);
// 输出：
// Array
// (
// [0] => Array
// (
// [name] => 张三
// [age] => 22
// )
// [1] => Array
// (
// [name] => 李四
// [age] => 23
// )
// [2] => Array
// (
// [name] => 王五
// [age] => 24
// )
// )
Method two: Specify using the "relative array method" Array index and then return <pre class="brush:php;toolbar:false">function get_students() {
$students[] = array("name" => "张三", "age" => 22);
$students[] = array("name" => "李四", "age" => 23);
$students[] = array("name" => "王五", "age" => 24);
return $students;
}
$all_students = get_students();
print_r($all_students);
// 输出：
// Array
// (
// [0] => Array
// (
// [name] => 张三
// [age] => 22
// )
// [1] => Array
// (
// [name] => 李四
// [age] => 23
// )
// [2] => Array
// (
// [name] => 王五
// [age] => 24
// )
// )</pre> via the
keyword. In both methods, use return to return the entire array. The returned array will be stored in a variable, and then you can use print_r() or var_dump() to view the contents of the returned array.
