Removing a file after sql execution in PHP - php

Question

I am trying to read multiple .sql files and then execute them into the database. This works, although now I am in need of deleting the file after its been successfully been imported to the database.
How would I be able to accomplish this?
<?php
function scan_for_sql_files($path){
$itdir = new \RecursiveIteratorIterator(
new \RecursiveDirectoryIterator($path, \RecursiveDirectoryIterator::SKIP_DOTS),
\RecursiveIteratorIterator::SELF_FIRST,
\RecursiveIteratorIterator::CATCH_GET_CHILD);
$files = array();
foreach ($itdir as $path=>$dir){
if ($dir->isFile()){
$ext = substr(strtolower($path), -3);
if($ext == 'sql'){
$files[] = array('path' => $path);
}
}
}
return $files;
}
//get files
$files = scan_for_sql_files('mysqls');
//Do sql
foreach($files as $file){
$sql = file_get_contents($file['path']);
$qr = $dbh->exec($sql);
}
?>

Answer 1

You can use unlink() function to delete the file.
unlink('test.html');
foreach($files as $file){
$sql = file_get_contents($file['path']);
$qr = $dbh->exec($sql);
if(is_file($file['path'])){
unlink($file['path']);
}
}

Answer 2

You can add the "unlink" function to get rid of the file
Simple modification :
foreach($files as $file){
$sql = file_get_contents($file['path']);
$qr = $dbh->exec($sql);
unlink($file['path']);
}

Answer 3

you can delete your sql file by this
unlink('database.sql');
or
you can delete sql file content by this
file_put_contents("database.sql", "");
if you are working on window os don't worry but if you are working in linux you have to set permission of all sql file other wise your file will not access by your php script
