PHP - 在单个变量中存储多个值[关闭]

Question

For example i have the PHP code like this

if ($rating_count == $rating_notnull) {
        $returnValue =  1;
    }
    if($project_count == $project_notnull) {
        $returnValue = 2;
    }

Now,I want to store two variable values into one single variable?

Answer 1

Arrays can be used to hold multiple values. They can have a key or not.

<?php

$x = array();

$x[] = 'Some Value';
$x[] = 'Another value';

var_dump($x);

$x = array();

$x['name'] = 'Anil';
$x['other name'] = 'Del Boy';

var_dump($x);

$x = array(
    'Name' => 'Batman',
    'Status' => 'Busy',
    'etc' => 'etc',
);

var_dump($x);
