在文件中搜索多个字符串并输出数据

Question

如何在.tsv文件中搜索与字符串的多个匹配项并将其导出到数据库？

我想做的是搜索一个名为mdata.tsv的大文件（1.5m行），以从数组中为其提供一个字符串。然后输出匹配的列数据。

当前的代码就是我所坚持的：

<?php 

$file = fopen("mdata.tsv","r"); //open file
$movies = glob('./uploads/Videos/*/*/*/*.mp4', GLOB_BRACE); //Find all the movies
$movID = array(); //Array for movies IDs
//Get XML and add the IDs to $movID()
foreach ($movies as $movie){ 
    $pos = strrpos($movie, '/');
    $xml = simplexml_load_file((substr($movie, 0, $pos + 1) .'movie.xml'));
    array_push($movID, $xml->id);

}

//Loop through the TSV rows and search for the $tmdbID then print out the movies category.
foreach ($movID as $tmdbID) { 
    while(($row = fgetcsv($file, 0, "\t")) !== FALSE) {
        fseek($file,0);
        $myString = $row[0];

        $b = strstr( $myString, $tmdbID );
        //Dump out the row for the sake of clarity.
        //var_dump($row);
        $myString = $row[0];
        if ($b == $tmdbID){
            echo 'Match ' . $row[0] .' '. $row[8];
        }       // Displays movie ID and category
    }
    }

fclose($file);

?>

tsv文件的示例：

tt0043936   movie   The Lawton Story    The Lawton Story    0   1949    \N  \N  Drama,Family
tt0043937   short   The Prize Pest  The Prize Pest  0   1951    \N  7   Animation,Comedy,Family
tt0043938   movie   The Prowler The Prowler 0   1951    \N  92  Drama,Film-Noir,Thriller
tt0043939   movie   Przhevalsky Przhevalsky 0   1952    \N  \N  Biography,Drama

似乎您可以通过使用in_array()而不是嵌套循环来简化此代码，以查看当前行是否在所需ID的列表中。确保此工作有效的一项更改是，您需要确保将字符串存储在$movID数组中。

$file = fopen("mdata.tsv","r"); //open file
$movies = glob('./uploads/Videos/*/*/*/*.mp4', GLOB_BRACE); //Find all the movies
$movID = array(); //Array for movies IDs
//Get XML and add the IDs to $movID()
foreach ($movies as $movie){
    $pos = strrpos($movie, '/');
    $xml = simplexml_load_file((substr($movie, 0, $pos + 1) .'movie.xml'));
    // Store ID as string
    $movID[] = (string) $xml->id;
}

while(($row = fgetcsv($file, 0, "\t")) !== FALSE) {
    if ( in_array($row[0], $movID) ){
        echo 'Match ' . $row[0] .' '. $row[8];
    }       // Displays movie ID and category
}
