如果语句在foreach循环字符检查

Question

我只需要在找到货币符号的迭代中运行foreach。目前，我有这个 -

$transferid = $key; 
$donation1 = $value["news"]; 
$donationcomma = getStringBetween($donation1,$from,$to); 
$donation = str_replace(',', '', $donationcomma); 
$playeridregex = preg_match("/XID=(.*)\"/", $donation1, $playerid); 
$playerid1 = preg_replace("/[^A-Za-z0-9'-]/","",$playerid[1]); 

，我可以反过来从字符串获得玩家ID

<a href = "http://www..com/.php?XID=1826888">saeed</a> donated $800,000,000 to the faction 

然而，因为它的立场，我只需要检查字符串包括金钱捐赠， $ 800,000,000。

包括在输出可以是这样的事情

<a href = "http://www..com/.php?XID=2023426">French_</a> donated 1 x First Aid Kit to the faction 

我需要不运行对字符串如这在foreach信息。

据我了解，你可以做这样的事情：

<?php 
foreach($values AS $key=>$value) { 
    if(preg_match('/^(\$)(.+)/', $value) == 1) { 
     $transferid = $key; 
     $donation1 = $value["news"]; 
     $donationcomma = getStringBetween($donation1,$from,$to); 
     $donation = str_replace(',', '', $donationcomma); 
     $playeridregex = preg_match("/XID=(.*)\"/", $donation1, $playerid); 
     $playerid1 = preg_replace("/[^A-Za-z0-9'-]/","",$playerid[1]); 
    } 
} 

但尽管如此，我不知道你在找什么。
