转换成字符串多维数组 [英] converting string into multidimensional array

问题描述

我想
转换此字符串：

I'd like to convert this string:

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

在此数组：

 $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)
      );

你会如何以最有效的方式做到这一点？

how would you do it in a most efficient way?

推荐答案

如果不使用常规的前pression你需要一些这样的循环使用正则表达式可能是最好的。

Without using regular expression you'll need some loops so using a regex may be best

$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);
