Question

我有如下所示的多维数组，

Array
(
    [14289] => Array
        (
            [0] => Ability:B,Itemname:Session #3: Tues June 28th - Fri July 8th (9-2:00PM)#1 only: 2pm
            [1] => Ability:B+,Itemname:Session #3: Tues June 28th - Fri July 8th (9-2:00PM)#1 only: 2pm
            [2] => Ability:B++,Itemname:Session #3: Tues June 28th - Fri July 8th (9-2:00PM)#1 only: 2pm
        )

    [14279] => Array
        (
            [0] => Ability:N/S,Itemname:Session #1: Tues May 31st - Fri June 10th (1-5:30PM)#1 only: 1pm
            [1] => Ability:N/S+,Itemname:Session #1: Tues May 31st - Fri June 10th (1-5:30PM)#1 only: 1pm
            [2] => Ability:N/S++,Itemname:Session #1: Tues May 31st - Fri June 10th (1-5:30PM)#1 only: 1pm
        )

    [14288] => Array
        (
            [0] => Ability:N/S,Itemname:Session #3: Tues June 28th - Fri July 8th (9-2:00PM)#1 only: 1:30pm
        )

    [14291] => Array
        (
            [0] => Ability:N/S+,Itemname:Session #4: Tues July 12th - Fri July 22nd (9-2:00PM)#1 only: 1pm
        )

    [14284] => Array
        (
            [0] => Ability:N/S++,Itemname:Session #2: Tues June 14th - Fri June 24th (9-2:00PM)#1 only: 1:30pm
        )

)

我需要从这个数组中获取值并将值分解为ability和itemname。

我该怎么做？。

Answer 1

假设$array包含您的数据，以下代码将执行此操作。

$result = array();
foreach($array as $a){
    foreach($a as $l){
        list($ab, $it) = explode(",", $l, 2);
        $ab = substr($ab, strlen("Ability:"));
        $it = substr($it, strlen("Itemname:"));
        $result[] = array(
            'Ability' => $ab,
            'Itemname' => $it
        );
    }
}

试试这个，它对我有用。我将所需的字符串与正则表达式匹配

<?php
$arr[][] = 'Ability:B,Itemname:Session #3: Tues June 28th - Fri July 8th (9-2:00PM)#1 only: 2pm';
$arr[][] = 'Ability:B+,Itemname:Session #3: Tues June 28th - Fri July 8th (9-2:00PM)#1 only: 2pm';
$arr[][] = 'Ability:B++,Itemname:Session #3: Tues June 28th - Fri July 8th (9-2:00PM)#1 only: 2pm';

$pattern = '/Ability:(.*),Itemname:(.*)$/m';

for ($i = 0; $i < count($arr); $i++) {
    for ($j = 0; $j < count($arr[$i]); $j++) {
        preg_match_all($pattern, $arr[$i][$j], $matchResult);
        echo 'Original string: '. $arr[$i][$j].'<br>';
        echo 'Ability: '.$matchResult[1][0].'<br>';
        echo 'Itemname: '.$matchResult[2][0].'<br>';
        echo '<br><hr><br>';
    }
}
?>
