php - 删除数组键前缀

Question

我有这种类型的数组，其中包含每个月的总收入:

Array ( [Total_Income_JAN] => 5000 [Total_Income_FEB] => 8000 [Total_Income_MAR] => 10000 )

如何从数组键中删除前缀部分，使其变为:

Array ( [JAN] => 4321 [FEB] => 2364 [MAR] => 2364 ) 

Answer 1

试试这个:

<?php

$list  = Array("Total_Income_JAN" => 5000, "Total_Income_FEB" => 8000 , "Total_Income_MAR" => 10000);

function removePrefix(array $input) {

    $return = array();
    foreach ($input as $key => $value) {
        if (strpos($key, 'Total_Income_') === 0)
            $key = substr($key, 13);

        if (is_array($value))
            $value = removePrefix($value); 

        $return[$key] = $value;
    }
    return $return;
}

$list = removePrefix($list);
print_r($list);

?>
