Delete files with special characters in filenames
I need to delete old files with special characters in filenames like space,,
,(
,)
,!
and so on via PHP. Classic unlink($filename)
does not work for these files. How can I transform 开发者_JAVA百科filenames to filenames which accepts unlink function and filesystem? It's running on a Solaris machine and I don't have another access to it.
How are you constructing the $filename
? unlink should work on any filename with special characters if you do the normal escaping on it. e.g.
for a file with a name of this has, various/wonky !characters in it
, then
$filename = 'this has\, various\/wonky \!characters in it';
unlink($filename);
should work.
unlink accepts any valid string and will try to delete the file in that string.
unlink('/home/user1/"hello(!,');
Perhaps you are not properly escaping certain characters.
You can also find all needed files and unlink them using RegexIterator:
<?php
$dir = new RecursiveDirectoryIterator('.');
$iterator = new RecursiveIteratorIterator($dir);
$regex = new RegexIterator($iterator, '/(^.*[\s\.\,\(\)\!]+.*)/', RecursiveRegexIterator::GET_MATCH);
foreach ($regex as $file) {
if (is_file($file[0])) {
print "Unlink file {$file[0]}\n";
unlink($file[0]);
}
}
This code snippet recursively traverse all directories from current ('.') and matches all files by regex '/(^.[\s\,.()!]+.)/', then delete them.
The way I do it in Linux is to use absolute paths, like "rm ./filename" that is dot slash.
You can also use escape charachters. Like "rm \-filename" that is - backspash hyphen.
