foreach and str_replace

[Confused but working on it]

So I've been trying to get a bit of code to:
Read all of the files in a dir called thumbs, but not the . and .., use
the filename in a link to get the same filename in an images dir. Now
I'm trying to use a foreach and glob as suggested, and get rid of the
part of the string that has the dir info. SO the below produces all my
thumbs nicely and all are links.

<?php
foreach (glob("thumbs/*.jpg") as $file)
{
str_replace('thumbs/', '', $file);
echo "<a href='images/$file'><img src='$file' class=\"pad1em\"></a>";
}
?>

But why doesn't the sring manipulatioon not work? I'm very grateful for
the line with the str_replace. If i remove the braces above i get the
last thumb and a bad link. Replace braces and I get all my thumbs. But
the link still has thumbs/ in it.

hmmm.

thx..ron

This does NOT alter $file. $file is not taken as a reference and altered
inside str_replace();

$file = str_replace('thumbs/', '', $file);

echo "<a href='images/$file'><img src='$file' class=\"pad1em\"></a>";
}
?>

Why do your images live in a thumbs dir and you still want an '/images/'
link?

However, this may help you:

<?php
foreach (glob("thumbs/*.jpg") as $file){
$filename = basename($file);
echo "<a href='images/$filename'><img src='$filename'
class='pad1em'></a>";
}
?>

You're not doing anything with the return value of str_replace().

I think you want:

$file = str_replace('thumbs/', '', $file);
