wordpress - 查找和替换字符串并将匹配的字符串转换为数字或货币

Question

如何在functions.php中查找和替换字符串并将匹配的字符串转换为数字或货币

内容：“<div>[myprice=100]</div> <div>[myprice=1000]</div> <div>[myprice=5000]</div>”

我想替换为：“<div>$ 100.00</div> <div>$ 1,000.00</div> <div>$ 5,000.00</div>”

但我得到下面的代码：“<div>100</div> <div>1000</div> <div>5000</div>”

function replace_myprice($content)
{
    $content = preg_replace('/\[myprice=([0-9^[]*)\]/', '\$ $1', $content);
    return $content;
}
add_filter('the_content','replace_myprice');
