I have a folder called MyFolder
with these three files:
file1 file2 file3.gif file.html
I need to add the extension '.gif' to the files with no extension. Then the first file1
and second file2
files should be targeted.
Result should be:
file1.gif file2.gif file3.gif file.html
The files are gif files, but somehow they lost the extensions. If I add the extension manually (editing its names) then I can load correctly in the browser
I'm trying with this code:
$directory = "http://www.example.com/MyFolder/";
if ($handle = opendir($directory)) {
while (false !== ($fileName = readdir($handle))) {
if($fileName['extension'] == ""){
$fileName = $fileName.".gif";
}
rename($directory . $fileName, $directory . $newName);
}
closedir($handle);
}
Unfortunately because you can't pass preg_grep
into array_walk
this had to be split like so, otherwise it could have been a single line.
$dir='./MyFolder/';
$col=preg_grep( '@^((?!gif).)*$@i', glob( $dir . '*' ) );
array_walk( $col , function($f){
rename( $f, $f.'.gif' );
});
Or, a modified version of the original
if( $handle = opendir( $directory ) ) {
while( false !== $filename = readdir( $handle ) ) {
if( !is_dir( $filename ) ) {
$file = $directory . $filename;
if( empty( pathinfo( $file, PATHINFO_EXTENSION ) ) ){
rename( $file, $file . '.gif' );
}
}
}
closedir($handle);
}
As the original above happily renamed files with extensions other than gif a more simple version without the faulty regex seems to work OK.
$dir='c:/temp/fileuploads/1/';
$col=glob( $dir . '*' );
array_walk( $col, function( $f ){
if( empty( pathinfo( $f, PATHINFO_EXTENSION ) ) ){
printf('%s - %s<br />',$f,$f.'.gif');
rename( $f, $f.'.gif' );
}
});
Change your rename to add the .gif
extension after you've detected that it is missing. Your current code was using a variable $newname
that didn't exist.
while (false !== ($fileName = readdir($handle))) {
if($fileName['extension'] == ""){
rename($directory . $fileName, $directory . $fileName . '.gif');
}
}
