问题
I have a folder called allfiles
, and there are some files in this folder, such as
1212-how-to-sddk-thosd.html
3454-go-to-dlkkl-sdf.html
0987-sfda-asf-fdf-12331.html
4789-how-to-fdaaf-65536.html
I use scandir
to list all files, and now I need to find the file by with keywords, example to-dlkkl
is the keyword, and I will get the file 3454-go-to-dlkkl-sdf.html
.
Glob seems not work, and opendir and readdir are not work well, any ideas?
回答1:
Use loop foreach
and strpos
function:
$files = scandir('allfiles');
foreach ($files as $file) {
if (strpos('to-dlkkl', $file) !== false) {
//file found
}
}
回答2:
you can use strstr to get actual file
$allfiles = scandir('./');
foreach ($allfiles as $file) {
if (strstr($file, 'to-dlkkl')) {
echo "file found"; //do what you want
}
}
回答3:
If You want to search specific file under directory then you can use preg_match()
.
<?php
if ($handle = opendir('/var/www/html/j')) { // here add your directory
$keyword = "index.php"; // your keyword
while (false !== ($entry = readdir($handle))) {
// (preg_match('/\.txt$/', $entry)) {
if (preg_match('/'.$keyword.'/i', $entry)) {
echo "$entry\n";
}
}
closedir($handle);
}
?>

I wonder why glob() function not working for it?
The below code should work I guess,
$existing_dir = getcwd();
// path to dir
chdir( '/var/www/allfiles/' );
foreach( glob( '*to-dlkkl*.html' ) as $html_file ) {
echo $html_file . '<br />';
}
chdir( $existing_dir );
