Question

我刚从这个网站上的某些人那里获得了帮助，并且能够让用户上传文本文件，并在上传过程中抓取文件并以编程方式搜索我指定的关键字。然后，该脚本计算找到该单词的次数，并将找到的整行输出到数组中。

因此，使用此代码时，示例结果会返回此信息：

$sceneINT = $sf->countKeyWord('INT', $file);

我的班级看起来像这样：

public static function countKeyWord($word, $file){
    if(!$word)
        return NULL;

    $contents = file_get_contents($file);

    #standardise those line endings
    $contents = str_replace(array("\r","\r\n","\n\r","\n"),"\n",$contents);
    $lines = explode("\n", $contents);

    #find your result
    $result = $line_num = array();
    foreach($lines as $line_num => $l)
        if(strpos($l, $word)) {
            $result[] = $l;
            $line_nums[] = $line_num;
        }

    echo "<pre>"; // I am echoing out the results for debugging purpuses
    print_r($result);
    echo "</pre>";
    return count($result); //final result shown to the user will only be the count
}

这样的结果如下：

我需要将结果上传到数据库中;

以数组[0]为例，我需要为数据库准备该行，使其看起来像这样

scene: 3
int_ext: INT
scene_name:    MARTEY'S OFFICE
day_night:    DAY

所有这些都将在数据库中排成一行，我不知道如何处理这个问题。如何获取结果并分成我需要的内容，然后将其发送到数据库，以便在用户按下SAVE按钮时存储找到的所有项目。

Answer 1

我刚刚做了一个非常快速的正则表达式。我相信你可以稍微整理一下，但它会给你一些东西。我会查找http://php.net/manual/en/function.preg-split.php

foreach($result as $line)
{
    $splitLine = preg_split("/(\d{1,3})[ ]+([A-Z.]{4}) ([A-Z' ]{1,}) - ([A-Z]{3,})/", $line);
}

那应该把它拆分成一个数组。我用你阵列的第一行测试了它。有一点需要注意的是，在阵列的每一行的第一个数字之前是否有任何填充空格尚不清楚 - 所以你可能不得不玩正则表达式。

Answer 2

您的代码有一些错误。

您创建数组$ line_num但使用$ line_nums添加条目
您不使用$ line_nums，为什么要创建它？

我会使用正则表达式来查找所有相关信息：

$contents = file_get_contents($file);
$pattern = "!INT\. (.*?) - (MORNING|NIGHT|DAY|LATER)!si";
preg_match_all($pattern, $contents, $matches);
echo '<pre>';
print_r($matches);
echo '</pre>';

如果你真的需要行号，你必须采取另一种方式：

使用preg_replace替换所有换行符：

//OLD: $contents = str_replace(array("\r","\r\n","\n\r","\n"),"\n",$contents);
//replaces even empty rows
$contents = preg_replace("!(\r|\n|\r\n\r\n|\r\r|\n\n)!s", "\n", $contents);

您可以使用m4rc的正则表达式来分割数据; - ）
