[SOLVED] only show certain files

[jacko310592]

i have the following code which shows all the file names of files on my webiste...

 

<?php
$files = new RecursiveDirectoryIterator("./");
foreach(new RecursiveIteratorIterator($files) as $files)
{
$files = basename($files);
echo ''.$files.'<br/>';
}
?>

 

 

my problem is that i only want this code to find files with a '#' at the begining of the files name, can anyone think of a way this code can be altered to do this.

 

thanks guys

Try this:

<?php
$files = new RecursiveDirectoryIterator("./");
foreach(new RecursiveIteratorIterator($files) as $files)
{
$file = basename($files);
if (strpos($file, '#') == 0) echo ''.$file.'<br/>';
}
?>

[newbtophp]

<?php
$files = new RecursiveDirectoryIterator("./");
foreach(new RecursiveIteratorIterator($files) as $files)
{
$file = basename($files);
if(preg_match('/^[#]/', $file)) {
echo ''.$file.'<br/>';
}
}
?>

 

Edited: Fixed regexp - thanks mikesta707

just so you know newb, your example will work for file names with the character # anywhere, rather than strictly at the top

$files = array("#file1", "file2", "file3", "fil#", "#file5");
foreach($files as $files)
{
$files = basename($files);
if(preg_match('/#/', $files)) {
	echo ''.$files.'<br/>';
}
}

output:

#file1
fil#
#file5

 

you probably meant

foreach($files as $files)
{
$files = basename($files);
if (preg_match('/^[#]/', $files)){
	echo ''.$files.'<br/>';
}
}

 

the ^ part matches to the beginning of the string

thanks for the reply Ken2k7, but that code continues to show all the files on the site-

 

also thanks to you newbtophp for a reply, but i got an error message when i tried your code :/

 

but mikesta707, you code worked perfectly, thanks allot

Oh sorry, I should have used 3 equal signs.

[jacko310592]

ahhh, now your code works, nice work (Y)

[Ken2k7]

For clarification purposes, one of the values strpos returns is false if the string is not found. And with 2 equal signs, false and 0 are the same. But they are not the same with 3 equal signs, which also check for types.
