PHP[数组键]：Convert"；0“；变成；“A”&引用；1“；变成；B"；。。。（因此，“89”将是“IJ”函数

假设我有这样一个数组：

$array = array
("this","is","me","and","I","am","an","array","hello","beautiful","world");

如何使用

Foreach

或…，创建将0转换为“a”、将1转换为“B”的函数

因此

 Array
(
    [0] => this
    [1] => is
    [2] => me
    [3] => and
    [4] => I
    [5] => am
    [6] => an
    [7] => array
    [8] => hello
    [9] => beautiful
    [10] => world
)

我会得到

 Array
(
    ['A'] => this
    ['B'] => is
    ['C'] => me
    ['D'] => and
    ['E'] => I
    ['F'] => am
    ['G'] => an
    ['H'] => array
    ['I'] => hello
    ['J'] => beautiful
    ['BA'] => world
)

（运行示例：）

如果您更喜欢

foreach

而不是

array\u-flip

+

array\u-map

，则可以使用此选项：

$result = array();
foreach($original as $k => $v) {
    $result[strtr($k, "0123456789", "ABCDEFGHIJ")] = $v;
}

$result = array();
foreach($original as $k => $v) {
    $result[strtr($k, "0123456789", "ABCDEFGHIJ")] = $v;
}
