只是想如果有人找到它的用途,我想分享这个。

基本上我需要一个 HTML 颜色列表来循环/循环。所以我需要删除数组的第一个元素,将它放在最后,然后获取当前的 HTML 颜色。

给定以下数组:

$colors = array(  
    "#2265fa", "#b61d1e", "#53b822", "#a9d81c", "#d6e9f5", "#43cc7d", "#e3159a", 
    "#80c85e", "#17b303", "#989240", "#014c07", "#d265f3", "#22bbb9", "#6c69a9", 
    "#7ea13a", "#0dcea2", "#99c27d", "#41405b", "#731801"
);

所以这就是我想出的。当然会有数百种方法可以做到这一点。这是我的看法。

# Array_shift returns the value it takes off the beginning of the array. 
# And I merely append this to the end of the array
$colors[] = array_shift($colors);

# Using current I am able to get the current first element of the array back
echo current($colors);

在这种情况下,它将是“#b61d1e”,即数组的当前索引。愿你在某处发现这很有用。
