如何在Php中将字符串拆分为两个数组

赛义德

我有一个这样的数组：

$array='{b_price,9500,b_discount,10,mainPrice,95000,total,95000,title,obj1},{b_price,1500,b_discount,15,mainPrice,15000,total,22500,title,obj2}'

我想首先拆分为两个数组，如下所示：

$array[0]={b_price,9500,b_discount,10,mainPrice,95000,total,95000,title,obj1}

和

$array[1]={b_price,1500,b_discount,15,mainPrice,15000,total,22500,title,obj2}

我用这段代码更改了每个数组

foreach ($b as $k => $m) {

                    if ($k % 2 == 0) {
                        $even[]= $m;
                    }
                    else {
                        $odd[] = $m;
                    }
                }

    $ff=array_combine($even,$odd);

我想要这样的输出变化

 Array( Array[0] =>  ([b_price] => 9500 [b_discount] => 10 [mainPrice] => 95000 [total] => 95000 [title] =>obj1)
Array[1] => ([b_price] => 1500 [b_discount] => 15 [mainPrice] => 15000 [total] => 22500 [title] => obj2))

两种做法：

-- 用途explode及array_map作用：

$str = '{b_price,9500,b_discount,10,mainPrice,95000,total,95000,title,obj1},{b_price,1500,b_discount,15,mainPrice,15000,total,22500,title,obj2}';

$result = array_map(function($v){
    $r = [];
    $arr = explode(',', trim($v, '{}'));
    foreach ($arr as $k => $v) {
        if (!($k % 2)) $r[$v] = $arr[$k+1];
    }
    return $r;
}, explode('},{', $str));

print_r($result);

-- 使用附加preg_match_all和array_combine功能：

$str = '{b_price,9500,b_discount,10,mainPrice,95000,total,95000,title,obj1},{b_price,1500,b_discount,15,mainPrice,15000,total,22500,title,obj2}';

$result = array_map(function($v){
    preg_match_all('/([^,]+),([^,]+),?/', trim($v, '{}'), $m);
    return array_combine($m[1], $m[2]);
}, explode('},{', $str));

print_r($result);

输出：

Array
(
    [0] => Array
        (
            [b_price] => 9500
            [b_discount] => 10
            [mainPrice] => 95000
            [total] => 95000
            [title] => obj1
        )

    [1] => Array
        (
            [b_price] => 1500
            [b_discount] => 15
            [mainPrice] => 15000
            [total] => 22500
            [title] => obj2
        )
)
