Prevent glob from selecting a file with a specific file name - php

Question

I have a folder with 5 html files. The files are called:
page-1.html
page-2.html
page-hello.html
page-32.html
yo-page-text.html
I wish to use glob function to return an array with only the files formatted: "page[number 0 - 1000]".
So essentially I wish the glob function to return the following pages from the example above:
page-1.html
page-2.html
page-32.html
This is the code that I have managed to write so far:
<?php
$directory = "testfolder/";
foreach (glob($directory . "page-*.html") as $filename) {
echo basename($filename);
}
?>

Answer 1

The glob pattern is not as flexible as RegEx, so unless someone has some other magic, you can filter after the glob:
$files = preg_grep('/page-[0-9]+\.html/', glob($directory . '*.*'));
If the glob pattern supported repetition + then it would be easy. Bash and Korn shells offer it with +([0-9]) but PHP doesn't.
You could also check for one number and trust that what follows matched by * will be numbers with: glob($directory . 'page-[0-9]*.html'), but this could match page-0-hello.html as well.

Answer 2

Assuming that your code works and that you get the basename of the files:
$name = basename($filename); //do not echo the basename
for ($i = 0; $i <= 1000; $i++) {
$trname = "page-$i";
if ($name == $trname) {
echo "$name";
}
}
Put one of these codes inside the foreach and get rid of echo basename($filename);. I'd recommend using the second one as nesting loops may prove to be a problem.
Note: This code can only work if your one works.
IMPORTANT EDIT:
My guess id that you want to do something (not echoing) the names, in which case:
function foo(bar) {
$arr = array();
$name = basename($filename);
$name = str_replace("page-", "", $name);
if (intval($name) < 1000 && intval($name) >= 0) {
$arr[] = $name;
}
}
Then, you can call on the function this way:
function foo() {
$arr = array();
$directory = "testfolder/";
foreach (glob($directory . "page-*.html") as $filename) {
$name = basename($filename);
$name = str_replace("page-", "", $name);
if (intval($name) < 1000 && intval($name) >= 0) {
$arr[] = $name;
}
}
}
$bar = foo();
foreach ($bar as $obj) {
//do something
}
