PHP用数据对展开字符串(PHP explode String with Data Pairs)

我有一个数据集，我想将它转换为一个数组，我只是不知道如何...我已经尝试了几个像preg_replace（）与正则表达式和爆炸（），但它不出来我需要它的方式。

所以我的数据集如下所示：

dataCrossID=12345, DeviceID=[ID=1234567] dataCrossID=5678, DeviceID=[ID=7654321] dataCrossID=67899, DeviceID=[ID=87654321]

并且数组应如下所示：

$dataSet( [12345] => 1234567, [5678] => 7654321, [67899] => 87654321, )

我尝试过正则表达式，但数字有不同长度的事实使我很难。

有人有想法吗？

I have a dataset and I want to conevert it into an array and I just can't figure out how... I've tried a couple things like preg_replace() with regex and explode() but it doesn't come out the way I need it.

So my dataset looks like this:

dataCrossID=12345, DeviceID=[ID=1234567] dataCrossID=5678, DeviceID=[ID=7654321] dataCrossID=67899, DeviceID=[ID=87654321]

and the Array should look like this:

$dataSet( [12345] => 1234567, [5678] => 7654321, [67899] => 87654321, )

I tried regex but the fact that the numbers got different lenghts makes it hard for me.

Does anyone have an idea?

使用preg_match_all()来标识您需要的文本片段：

$input = <<< E dataCrossID=12345, DeviceID=[ID=1234567] dataCrossID=5678, DeviceID=[ID=7654321] dataCrossID=67899, DeviceID=[ID=87654321] E; preg_match_all('/dataCrossID=(\d+), DeviceID=\[ID=(\d+)\]/', $input, $matches, PREG_SET_ORDER); print_r($matches);

$matches的内容是：

Array ( [0] => Array ( [0] => dataCrossID=12345, DeviceID=[ID=1234567] [1] => 12345 [2] => 1234567 ) [1] => Array ( [0] => dataCrossID=5678, DeviceID=[ID=7654321] [1] => 5678 [2] => 7654321 ) [2] => Array ( [0] => dataCrossID=67899, DeviceID=[ID=87654321] [1] => 67899 [2] => 87654321 ) )

您现在可以迭代$matches并使用位置1和2处的值作为键和值来将数据提取到所需的数组中：

$output = array_reduce( $matches, function(array $c, array $m) { $c[$m[1]] = $m[2]; return $c; }, array() ); print_r($output);

输出是：

Array ( [12345] => 1234567 [5678] => 7654321 [67899] => 87654321 )

Use preg_match_all() to identify the pieces of text you need:

$input = <<< E dataCrossID=12345, DeviceID=[ID=1234567] dataCrossID=5678, DeviceID=[ID=7654321] dataCrossID=67899, DeviceID=[ID=87654321] E; preg_match_all('/dataCrossID=(\d+), DeviceID=\[ID=(\d+)\]/', $input, $matches, PREG_SET_ORDER); print_r($matches);

The content of $matches is:

Array ( [0] => Array ( [0] => dataCrossID=12345, DeviceID=[ID=1234567] [1] => 12345 [2] => 1234567 ) [1] => Array ( [0] => dataCrossID=5678, DeviceID=[ID=7654321] [1] => 5678 [2] => 7654321 ) [2] => Array ( [0] => dataCrossID=67899, DeviceID=[ID=87654321] [1] => 67899 [2] => 87654321 ) )

You can now iterate over $matches and use the values at positions 1 and 2 as keys and values to extract the data into the desired array:

$output = array_reduce( $matches, function(array $c, array $m) { $c[$m[1]] = $m[2]; return $c; }, array() ); print_r($output);

The output is:

Array ( [12345] => 1234567 [5678] => 7654321 [67899] => 87654321 )
