如果語句在foreach循環字符檢查

Question

我只需要在找到貨幣符號的迭代中運行foreach。目前，我有這個 -

$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]); 

，我可以反過來從字符串獲得玩家ID

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

然而，因爲它的立場，我只需要檢查字符串包括金錢捐贈， $ 800,000,000。

包括在輸出可以是這樣的事情

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

我需要不運行對字符串如這在foreach信息。

據我瞭解，你可以做這樣的事情：

<?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]); 
    } 
} 

但儘管如此，我不知道你在找什麼。
