Question

所以，我有这段代码：

        } else {

            $photograph_moderation = new PhotographModeration($this->photograph_id);
            $photograph_moderation->purgePhotograph();

            //eventually take to an error page
            die('image is not big enough to upload');

        }

当满足此条件时，将正确调用purgePhotograph（）函数，但脚本永远不会死亡。有没有理由为什么死不会在这里被称为？ purgePhotograph（）也没有脚本执行命令。

这是purge_photograph功能：

public function purgePhotograph() {

    $db = Connect::connect();
    $photograph_id = $db->real_escape_string($this->photograph_id);

    $query = "SELECT * from photographs WHERE id='{$this->photograph_id}'";
    $result = $db->query($query);
    $photograph = $result->fetch_assoc();

    if ($photograph['location'])
    unlink($photograph['location']);

    if ($photograph['thumbnail_location'])
    unlink($photograph['thumbnail_location']);

    if ($photograph['watermark_location'])
    unlink($photograph['watermark_location']);

    if ($photograph['xsmall_location'])
    unlink($photograph['xsmall_location']);

    if ($photograph['small_location'])
    unlink($photograph['small_location']);

    if ($photograph['medium_location'])
    unlink($photograph['medium_location']);

    if ($photograph['large_location'])
    unlink($photograph['large_location']);

    if ($photograph['xlarge_location'])
    unlink($photograph['xlarge_location']);

    if ($photograph['xxlarge_location'])
    unlink($photograph['xxlarge_location']);

    if ($photograph['xxxlarge_location'])
    unlink($photograph['xxxlarge_location']);

    $query = "DELETE from photographs WHERE id='{$this->photograph_id}'";
    $result = $db->query($query);

    $query = "DELETE from photograph_tags WHERE photograph_id='{$this->photograph_id}'";
    $result = $db->query($query);

}

Answer 1

检查purgePhotograph（）是否返回。也许它有一个死循环或需要很长时间。

Answer 2

也许现在是时候安装php debugger module并进入有问题的代码 xdebug例如netbeans因为前端工作得很好。

Answer 3

哇，问题是purgePhotograph（）从未有过返回1;在末尾。我不知道这是执行以下行所必需的。

Answer 4

尝试将其放入try / catch块中。也许有些事情会在死亡被执行之前抛出异常。

您收到任何错误吗？
