PHP排序爲從文本文件中讀取的升序數據

我有一個工作數據解析php腳本，它返回與它們相關的電影標題和評級。PHP排序爲從文本文件中讀取的升序數據

PHP腳本是這樣的：

<?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"; 
    } 
}

輸出是這樣的：

最簡單的方法可能是使用usort。您可以定義一個函數來比較$titles中的項目。
