Hey

[Owen]

I am currently making a gallery and have come a long way.

What I want to do now is:
$title=$name

where $name is file-with-dashes.jpg

Now I want $title to be $name with dashes replaced with spaces and .jpg removed.

I have shortened text before but never chopped off the ending...

[NTLDR]

$title = substr(str_replace('-', ' ', $name), 0, -4);

Should do it.

[Owen]

thanks man! I'll post a link to the gallery here once it's done.

[Boofo]

$title = substr(str_replace('-', ' ', $name), 0, -4);

Should do it.

I'm curious, what is the 0 and the -4 in this code for?

[NTLDR]

The 0 is the start position and the -4 is the end position, ie chop 4 characters off the end.

[Boofo]

Oh, ok, you mean like chop off the .jpg or .gif?

[NTLDR]

Yep :)

[Boofo]

Thanks! See? Even an old dog can learn new tricks. ;)

[Owen]

What if I want to display the first word that comes before a dash?

like:
file-with-dashes.jpg = file

[NTLDR]

$parts = explode('-', $name);
$file = $parts[0];

[Owen]

<?php
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo "$file\n";
}
}
closedir($handle);
}
?>

How do I exclude index.php from this? and if possible anything other than folders.

[Dean C]

www.php.net/is_dir function checks for directories :)

[Owen]

Yup I figured it out. I used the readdir function.

[Owen]

How do I get rid of those dots? Also how do I sort this alphabetically?


<?php
$path = "."; // even "."
if ($dir = @opendir($path)) {
while (($file = readdir($dir)) !== false) {
if (is_dir($path."/".$file)) {
echo $file."<br />";
}
}
closedir($dir);
}
?>


Displays:
.
..
Ford
Infiniti
Mercedes
BMW
Nissan
Volvo

[Owen]

Well I did an extremely crude fix:


<?php
$path = "."; // even "."
if ($dir = @opendir($path)) {
while (($file = readdir($dir)) !== false) {
if (is_dir($path."/".$file)) {
$title = str_replace('.', '<img width=0 height=0 border=0>', $file);
echo "<a href=\"$file/\">$title<a/><br>";
}
}
closedir($dir);
}
?>

The 2nd argument of str_replace can be blank. You can substitute the first argument with an empty string, instead of using an image tag (which makes no sense).

[Owen]

No if I put a space in the br's have effect, but if there is 0 pix images there is nothing to <br>
