我每天至少写上10亿菲律宾比索。是否有任何人知道采用PHP功能或物体使以下代码动态的冷却技术?

$results = mysql_query("SELECT blah FROM blah_blah");       
while ($row = mysql_fetch_array($results)) {
//execute statements here
}

根据“Bryan”的评论,你可以做像PHP5.3+那样的事情:

function applyStatements($query, $callback) {
    $result = array();
    $mysqlResult = mysql_query($query);
    while ($row = mysql_fetch_assoc($mysqlResult)) {
        $result[] = $callback($row);
    }
    return $result;
}

$result = applyStatements( SELECT foo FROM bar , function ($row) {
    return $row[ baz ];
});

(如MySQL故障,需要进一步处理错误)
