import database by php code

 Here I explain you how to import database by PHP code.

<?php
// Name of the data file
$filename = 'u6357583.zip';
// MySQL host
$mysqlHost = 'localhost';
// MySQL username
$mysqlUser = 'root';
// MySQL password
$mysqlPassword = '';
// Database name
$mysqlDatabase = 'u635758';
// Connect to MySQL server
$link = mysqli_connect($mysqlHost, $mysqlUser, $mysqlPassword, $mysqlDatabase) or die('Error connecting to MySQL Database: ' . mysqli_error());

$tempLine = '';
// Read in the full file
$lines = file($filename);
// Loop through each line
foreach ($lines as $line) {
    // Skip it if it's a comment
    if (substr($line, 0, 2) == '--' || $line == '')
        continue;
    // Add this line to the current segment
    $tempLine .= $line;
    // If its semicolon at the end, so that is the end of one query
    if (substr(trim($line), -1, 1) == ';')  {
        // Perform the query
        mysqli_query($link, $tempLine) or print("Error in " . $tempLine .":". mysqli_error());
        // Reset temp variable to empty
        $tempLine = '';
    }
}
 echo "Tables imported successfully";

Find file and remove from whole folder by php code

 Hello

Here I explain find the specific file and remove it from whole folder. 

For example: There is many .htaccess files in every folder. Or any file created by virus or any script. You want to remove it. So you have to open every folder and remove it. Instead of this you can remove it by this code.

<?php
function getDirContents($dir, &$results = array()) {
    $files = scandir($dir);
    foreach ($files as $key => $value) {
        $path = realpath($dir . DIRECTORY_SEPARATOR . $value);
        if (!is_dir($path)) {
            $results[] = $path;
        } else if ($value != "." && $value != "..") {
            getDirContents($path, $results);
            $results[] = $path;
        }
    }
    return $results;
}
$i =1;
$files = getDirContents('FolderName');
foreach($files as $file){ // iterate files
  if (strpos($file, '.htaccess') !== false) {
    if (unlink($file)) {
  echo $i. "Delete file :".$file."<br>"; 
  $i++;
  }
}
}
?>

FolderName  means your website folder name
