php - 正则表达式 - PHP

Question

我正在使用以下 PHP 代码

<?
    $data = file_get_contents('http://www.kitco.com/texten/texten.html');
    preg_match_all('/([A-Z]{3,5}\s+[0-9]{1,2},[0-9]{4}\s+([0-9.NA]{2,10}\s+){1,7})/si',$data,$result);

    $records = array();
    foreach($result[1] as $date) {
        $temp = preg_split('/\s+/',$date);
        $index = array_shift($temp);
        $index.= array_shift($temp);
        $records[$index] = implode(',',$temp);
    }
    print_R($records);
?>

读取以下数据

我不确定您是否可以修改现有的正则表达式以轻松匹配两个表，但如果您在字符串中有第二个表，则可以使用:

$string = "PLAIN TEXT TABLE DATA HERE";

preg_match('/Gold\s+(\d+\.\d{2})\s+(\d+\.\d{2})/',$string,$matches);

$goldBid = $matches[1];
$goldAsk = $matches[2];
