如果在foreach循环char中的语句检查

问题描述：

I need to only run the foreach on iterations that find a currency symbol. Currently, I have this -

$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]);

which I can in turn get the player ID from the string

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

However, as it stands, I need to only check strings that include the money donation, $800,000,000.

Included in the output can be such things as

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

I need to not run the foreach info on strings such as this.

答

from what i understand, you could do something like this :

<?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]);
    }
}

But still, i'm not sure what you are looking for.
