将Python片段转换为PHP？

Question

任何人都可以将我的小Python代码片段转换为PHP吗？我对这两种语言都不熟悉。 :(

matches = re.compile("\"cap\":\"(.*?)\"") 
totalrewards = re.findall(matches, contents) 
print totalrewards 

谢谢你对那些谁愿意帮助:(

这是代码的直接翻译上面，用填充用于演示的“内容”：

<?php 
$contents = '"cap":"foo" "cap":"wahey"'; 
if (preg_match_all('/"cap":"(.*?)"/', $contents, $matches, PREG_SET_ORDER)) { 
    var_dump($matches); 
} 

输出：

array(2) { 
    [0]=> 
    array(2) { 
    [0]=> 
    string(11) ""cap":"foo"" 
    [1]=> 
    string(3) "foo" 
    } 
    [1]=> 
    array(2) { 
    [0]=> 
    string(13) ""cap":"wahey"" 
    [1]=> 
    string(5) "wahey" 
    } 
} 

如果你想实际做一些结果，例如列出它，请尝试：

<?php 
$contents = '"cap":"foo" "cap":"wahey"'; 
if (preg_match_all('/"cap":"(.*?)"/', $contents, $matches, PREG_SET_ORDER)) { 
    foreach ($matches as $match) { 
     // array index 1 corresponds to the first set of brackets (.*?) 
     // we also add a newline to the end of the item we output as this 
     // happens automatically in PHP, but not in python. 
     echo $match[1] . "\n"; 
    } 
}
