Php 将字符串转换为多维数组

我想 转换此字符串：

$credit_packages_string = "300,0.25|1000,0.24|3000,0.22|4000,0.20|5000,0.18|6000,0.16|7000,0.14";

在该阵列中：

 $credit_packages = array(  array( 'credit_amount'=> 300,
      'price_per_credit'=>0.25),
      array( 'credit_amount'=> 1000,
      'price_per_credit'=>0.24),
      array( 'credit_amount'=> 3000,
      'price_per_credit'=>0.22),
      array( 'credit_amount'=> 4000,
      'price_per_credit'=>0.20),
      array( 'credit_amount'=> 5000,
      'price_per_credit'=>0.18),
      array( 'credit_amount'=> 6000,
      'price_per_credit'=>0.16),
      array( 'credit_amount'=> 7000,
      'price_per_credit'=>0.14)
      );

您将如何以最有效的方式进行

$array = explode(',', explode('|', $credit_packages_string));

这只会给你一个数值数组。如果您确实需要“信用额”和“每信用额的价格”键，请添加以下内容：

foreach($i as &$array) {
    $i['credit_amount'] = $i[0];
    $i['price_per_credit'] = $i[1];
}

你可以用as

如果不使用正则表达式，您将需要一些循环，因此使用正则表达式可能是最好的选择

$credit_packages_string = "300,0.25|1000,0.24|3000,0.22|4000,0.20|5000,0.18|6000,0.16|7000,0.14";
preg_match_all( '~(?P<credit_amount>\d+),(?P<price_per_credit>[\d\.]+)~', $credit_packages_string, $matches, PREG_SET_ORDER );
print_r($matches);

$credit|u packages_string=“300,0.25 | 1000,0.24 | 3000,0.22 | 4000,0.20 | 5000,0.18 | 6000,0.16 | 7000,0.14”；
preg_match_all（“~（？P\d+），（？P[\d\.]+）~”，$credit_packages_string，$matches，preg_SET_ORDER）；
打印（匹配项）；

截至目前，共有7种观点和4种答案：）

$credit_packages_string = "300,0.25|1000,0.24|3000,0.22|4000,0.20|5000,0.18|6000,0.16|7000,0.14";
preg_match_all( '~(?P<credit_amount>\d+),(?P<price_per_credit>[\d\.]+)~', $credit_packages_string, $matches, PREG_SET_ORDER );
print_r($matches);
