Question

我的数组看起来像这样

Array
(
    [0] => Array
        (
            [width] => 1
            [ladiesSeat] => 
            [fare] => 610
            [zIndex] => 0
            [serviceTaxAmount] => 35.38
            [commission] => 
            [operatorServiceChargeAbsolute] => 0
            [operatorServiceChargePercent] => 0
            [totalFareWithTaxes] => 645.38
            [bookedBy] => 
            [ac] => 
            [sleeper] => 
            [serviceTaxPer] => 5.8
            [available] => 1
            [row] => 0
            [column] => 2
            [length] => 1
            [id] => M1
        )

    [1] => Array
        (
            [width] => 1
            [ladiesSeat] => 
            [fare] => 610
            [zIndex] => 0
            [serviceTaxAmount] => 35.38
            [commission] => 
            [operatorServiceChargeAbsolute] => 0
            [operatorServiceChargePercent] => 0
            [totalFareWithTaxes] => 645.38
            [bookedBy] => 
            [ac] => 
            [sleeper] => 
            [serviceTaxPer] => 5.8
            [available] => 1
            [row] => 1
            [column] => 0
            [length] => 1
            [id] => L21
        )
      ...............
      ...............
     [n] => Array
        (
            [width] => 1
            [ladiesSeat] => 
            [fare] => 610
            [zIndex] => 0
            [serviceTaxAmount] => 35.38
            [commission] => 
            [operatorServiceChargeAbsolute] => 0
            [operatorServiceChargePercent] => 0
            [totalFareWithTaxes] => 645.38
            [bookedBy] => 
            [ac] => 
            [sleeper] => 
            [serviceTaxPer] => 5.8
            [available] => 1
            [row] => 0
            [column] => 0
            [length] => 1
            [id] => L21
        )
)

我想根据row和column键的值按升序对此数组进行排序。这是预期的结果。

即当我在排序的关联数组中打印row和column键的值时它看起来应该是这样的。

 00
 02
 12

那么我该如何排序呢？

为了便于阅读，您可能需要稍微清理一下，功能有点乱，但它应该完成工作。任何问题都让我知道。

function rowColumnSort($a, $b) {
    // Row is lower.
    if ($a['row'] < $b['row']) {
        return -1;
    }

    // Rows Match, check columns
    if ($a['row'] == $b['row']) {
        // Column Higher
        if ($a['column'] > $b['column']) {
            return 1;   
        } else {
            // Column lower
            return -1;
        }
    }

    // Row is higher
    if ($a['row'] > $b['row']) {
        return 1;
    }
}

usort($arr, 'rowColumnSort');
