我有一个工作数据解析 php 脚本，它返回与它们相关的电影标题和评级。
php 脚本如下所示：
<?php
header("content-type: text/plain");
foreach (glob("*.mov") as $filename)
$theData = file_get_contents($filename) or die("Unable to retrieve file data");
$months = ['January' => '_01', 'February' => '_02', 'March' => '_03', 'April' => '_04', 'May' => '_05', 'June' => '_06', 'July' => '_07', 'August' => '_08', 'September' => '_09', 'October' => '_10', 'November' => '_11', 'December' => '_12'];
foreach($months as $key => $month){
if(strpos($filename,$month)!==false){
echo "Movie List for $key 2013\n\n";
}
}
$string = $theData;
$titles = explode("\n", $string);
function getInfo($string){
$Ratings = ['G', 'PG', 'PG-13', 'R', 'NR', 'XXX'];
$split = preg_split("/\"(.+)\"/", $string, -1, PREG_SPLIT_DELIM_CAPTURE);
if(count($split) == 3){
preg_match("/(".implode("|", $Ratings).")\s/", $split[0], $matches);
$rating = $matches[0];
return ["title" => $split[1], "rating" => $rating];
}
return false;
}
foreach($titles as $title){
$info = getInfo($title);
if($info !== false){
echo "{$info["title"]} : {$info["rating"]}\n";
}
}
输出如下所示：
