PHP: How can I grab a single file from a directory without scanning entire directory?
directory, file, php
Solution
This should do it:
<?php
$h = opendir('./'); //Open the current directory
while (false !== ($entry = readdir($h))) {
if($entry != '.' && $entry != '..') { //Skips over . and ..
echo $entry; //Do whatever you need to do with the file
break; //Exit the loop so no more files are read
}
}
?>
readdir
Returns the name of the next entry in the directory. The entries are returned in the order in which they are stored by the filesystem.
Problem
I have a directory with 1.3 Million files that I need to move into a database. I just need to grab a single filename from the directory WITHOUT scanning the whole directory. It does not matter which file I grab as I will delete it when I am done with it and then move on to the next. Is this possible? All the examples I can find seem to scan the whole directory listing into an array. I only need to grab one at a time for processing... not 1.3 Million every time.
