[英]php scan_it to exclude directories starting with an underscore
I have the following code, which scans the specified directory for jpgs: 我有以下代码,它扫描指定的目录中的jpgs:
<?php
$scan_it = new RecursiveDirectoryIterator("images/" . $this->item->extraFields->PropertYID->value . "");
foreach(new RecursiveIteratorIterator($scan_it) as $file) {
if (strtolower(substr($file, -4)) == ".jpg" &&
strtolower(substr($file, -4)) == ".jpg") {
echo '<div><img src="'.$file .'" alt="" />'."</div>";
}
}
?>
Id simply like to exclude from this scan any folders which name start with an underscore (_). 我只想在此扫描中排除任何名称以下划线(_)开头的文件夹。
To clarify if the directory structure was the following: 澄清目录结构是否如下:
/images/interior/
/images/exterior/
/images/_room1/
/images/room2/
/images/room3/
All directories except _room1 would be included. 将包括除_room1之外的所有目录。
Many thanks in advance! 提前谢谢了!
You can search for '_' in the folder name 您可以在文件夹名称中搜索“_”
$directory = "images/' . $this->item->extraFields->PropertYID->value '";
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory), RecursiveIteratorIterator::CHILD_FIRST);
foreach($files as $name => $file){
if(is_dir($file)){ //Edited
$pos = strpos($file, '_');
}
if($pos === false){
if (strtolower(substr($file, -4)) == ".jpg" &&
strtolower(substr($file, -4)) == ".jpg") {
echo '<div><img src="'.$file .'" alt="" />'."</div>";
}
}
}
If you want to remove directory with only the first character as '_' and its ok if its in middle then you can do this 如果你想删除只有第一个字符为'_'的目录,如果它在中间,那就ok了,那么你可以这样做
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory), RecursiveIteratorIterator::CHILD_FIRST);
foreach($files as $name => $file){
if(is_dir($file)){
$pos = strpos($file, '_');
}
if(($pos === false) || $pos>0){
if (strtolower(substr($file, -4)) == ".jpg" &&
strtolower(substr($file, -4)) == ".jpg") {
echo '<div><img src="'.$file .'" alt="" />'."</div>";
}
}
}
