我正在尝试创建一个脚本,从某个文件夹中的多个目录中读取.sql文件,然后将它们执行到数据库中。
如何让我的代码能够读取多个文件夹。 [将来会添加/删除这些文件夹,所以我需要它来自动查找任何没有任何部分名称的文件夹。
所以例如我有一个名为“mysqls”的文件夹,在该文件夹中我有其他文件夹,例如'text1','test2'。 Test1和test2有不同的.sql文件,我希望这样做。
<?php
$dirf = 'mysqls';
$dir = scandir($dirf);
unset($dir['0']);
unset($dir['1']);
foreach($dir as $file) {
$sql = file_get_contents($dirf . '/'. $file);
$qr = $dbh->exec($sql);
}
?>

$directory = new RecursiveDirectoryIterator('mysqls');
// Filter out "dot" folders
$filter = new DirnameFilter($directory, '/^(?!\.)/');
// Filter sql files
$filter = new FilenameFilter($filter, '/(?:sql)$/i');
foreach(new RecursiveIteratorIterator($filter) as $file) {
$sql = file_get_contents($file);
$qr = $dbh->exec($sql);
}
abstract class FilesystemRegexFilter extends RecursiveRegexIterator {
protected $regex;
public function __construct(RecursiveIterator $it, $regex) {
$this->regex = $regex;
parent::__construct($it, $regex);
}
}
class FilenameFilter extends FilesystemRegexFilter {
// Filter files against the regex
public function accept() {
return ( ! $this->isFile() || preg_match($this->regex, $this->getFilename()));
}
}
class DirnameFilter extends FilesystemRegexFilter {
// Filter directories against the regex
public function accept() {
return ( ! $this->isDir() || preg_match($this->regex, $this->getFilename()));
}
}

<?php

new \RecursiveDirectoryIterator($path, \RecursiveDirectoryIterator::SKIP_DOTS),

$files = array();
foreach ($itdir as $path=>$dir){
if ($dir->isFile()){
$ext = substr(strtolower($path), -3);
if($ext == 'sql'){

}
}
}
return $files;
}
//get files
$files = scan_for_sql_files('mysqls');
//Do sql
foreach($files as $file){
$sql = file_get_contents($file['path']);

$iterator = new RecursiveDirectoryIterator('mysqls');
foreach($iterator as $fileinfo){
if('sql' == $fileinfo->getExtension()){
$sql = file_get_contents($fileinfo->getPathname());
