如何从字符串中提取数字并添加到数组？

Question

I want to convert this string:

<5> 20825.24 </ 5> <7> 0.0 </ 7> <8> 0.0 </ 8>

to an array with key value

I would really appreciate the help

I tried different xmlParse strategies but it is not exactly an xml.

$xml = new \SimpleXMLElement("<5>20825.24</5><7>0.0</ 7><8>0.0</8>");

Response: String could not be parsed as XML

I expect an array like this:

[5=>20825.24,7=>0.0,8=>0.0]

Answer 1

<?php

$subject = '<5> 20825.24 <7> 0.0 <8> 0.0';
$pattern = '/\<(\d)\>\s+(\d+\.\d+)/u';
$result = preg_match_all($pattern,$subject,$output);

$numbers = $output[1];
$output = $output[2];
$outTotal = [];

foreach ($numbers as $key => $number) {
    $outTotal[$number] = $output[$key];
}
var_dump($outTotal);

gives:

array(3) {
  [5]=>
  string(8) "20825.24"
  [7]=>
  string(3) "0.0"
  [8]=>
  string(3) "0.0"
}
