变量名设置为键,其值设置为数组中的值

Question

我想设置一个变量加载然后循环,然后将它们添加到一个数组,键设置为变量名,如下所示.

我只是不确定你是如何创建循环的.

// create an array
$array = array();

// Set up Variable
$green  = "31d944";
$red    = "d92929";
$blue   = "1b43d9";
$pink   = "d96ad8";
$orange = "d98225";

// Loop though - not sure how this would work...
for($i=0; $i<5; $i++){
    $array[] = $varNmae => $green;
}

// Output something like below
$array['green']; // output '31d944'
$array['red'];  // output 'd92929'
$array['blue']; // output '1b43d9'
$array['pink']; // output 'd96ad8'
$array['orange']; // output 'd98225'

Answer 1

compact()与extract()(将关联数组提取到本地符号表中)相反,并且是您要使用的.

$array = compact("green", "red", "blue", "pink", "orange");

CodePad.

Answer 2

该功能compact正是如此:

$array = compact('green', 'red', 'blue', 'pink', 'orange');
