PHP函数返回数组 [英] PHP function return array

问题描述

  
我需要从一个函数返回多个值，因此我将它们添加到一个数组并返回了数组。 < ;? 
 
函数data（）{
 
 $ a =abc; 
 $ b =def; 
 $ c =ghi; 
 
返回数组（$ a，$ b，$ c）; 
} 
 
 
？> 
  

如何获得 $ a ， $ b ， $ c 通过调用上述函数？




=h2_lin>解决方案

 函数data（）{
 $ out ['a'] =abc; 
 $ out ['b'] =def; 
 $ out ['c'] =ghi; 
返回$ out; 
} 
 
 $ data = data（）; 
 echo $ data ['a']; 
 echo $ data ['b']; 
 echo $ data ['c']; 
  




I need to return multiple values from a function, therefore I have added them to an array and returned the array.

<?

function data(){

$a = "abc";
$b = "def";
$c = "ghi";

return array($a, $b, $c);
}


?>

How can I receive the values of $a, $b, $c by calling the above function?

解决方案

You can add array keys to your return values and then use these keys to print the array values, as shown here:

function data() {
    $out['a'] = "abc";
    $out['b'] = "def";
    $out['c'] = "ghi";
    return $out;
}

$data = data();
echo $data['a'];
echo $data['b'];
echo $data['c'];
