PHP脚本完成后删除文件

Question

我有以下的php文件，它执行cron作业。如何添加一旦完成的功能，目录中的xml文件就会被删除。

<?php 

// Create connection 
$con=mysqli_connect("localhost","test","test","epg"); 

// Check connection 
if (mysqli_connect_errno()) 
    { 
    echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
    } 

$dir = "xml-files/"; 
if (is_dir($dir)) { 
    if ($dh = opendir($dir)) { 
    while (($file = readdir($dh)) !== false) { 
     if (($file !== '.') && ($file !== '..')) { 
    $doc = simplexml_load_file($dir . $file); 

foreach ($doc->ScheduleData->ChannelPeriod as $channelPeriod) 
{ 
    $channelId = $channelPeriod->ChannelId; 

    foreach ($channelPeriod->Event as $event) 
    { 
     $beginTime = $event['beginTime']; 
     $duration = $event['duration']; 
     $programName = $event->EpgProduction->EpgText->Name; 
     $description = $event->EpgProduction->EpgText->Description; 
     $EventId = $event->EventId; 

     $sql = "insert into `epg` (`EventId`,`ChannelId`, `BeginTime`,`Duration`, `ShortName`, `Description`) values ('$EventId','$channelId', '$beginTime','$duration', '$programName', '$description')"; 

     if (mysqli_query($con,$sql)) 
     { 
     echo "Database updated successfully"; 
     } 
    else 
     { 
     echo "Error creating database: " . mysqli_error($con); 
     } 

    } 
} 
} 
    } 
    closedir($dh); 
    } 
} 
?> 

非常感谢您的帮助！非常感激。

在你的代码的结束unlink($filename);功能删除文件;

function deleteFiles($dir) { 
    $files = glob($dir); 
    foreach($files as $file){ 
     if(is_file($file)) 
     unlink($file); 
    } 
} 

deleteFiles("xml-files/*"); This will delete all files under this dir

取消链接功能删除文件。如果您有多个文件，请循环访问目录，然后为每个文件执行该功能。

Answer 3

你使用可以一次PHP脚本完成

Answer 4

http://php.net/manual/en/function.register-shutdown-function.php

可以定义关机功能，只要脚本完成或退出该函数被调用：

function delete_files() { 
    // delete files here 
} 

register_shutdown_function('delete_files');
