我有一个数组

 Array
(
    [0] => 34
    [1] => 04:32 PM
    [2] => 05:32 PM
    [3] => MNL | ITLY
    [4] => 2h 10m
    [5] =>   PHP 9,222
    [6] => 33
    [7] => 04:32 PM
    [8] => 04:32 PM
    [9] => ITLY | MNL
    [10] => 2h 10m
    [11] =>    PHP 7,227
)

如何对索引5和11的值执行算术运算。

Answer 1

通过使用preg_replace，您可以删除＆＃39; PHP＆＃39;部分和来自价值的逗号。

echo preg_replace('|  PHP (\d+),(\d+)|', '$1$2', $array[5]) + preg_replace('|  PHP (\d+),(\d+)|', '$1$2', $array[11]);

或者如果空格的数量是随机的＆＃39; \ s＆＃39;是任何空白字符

    echo preg_replace('|\s+PHP\s+(\d+),(\d+)|', '$1$2', $array[5]) + preg_replace('|\s+PHP\s+(\d+),(\d+)|', '$1$2', $array[11]);

或str_replace（）
