File List

[MaxD]

Project: to read the files in a directory, extract the image files, sort by name, and create an index.

1: How do I get a list of files in a directory?

Can I use strstr() to seperate the .gif and .jpg files and then again to sort the out if I name the files using a convention like "thumbnail_file1.gif, image_file1.jpg"

You can use directory functions within PHP - the following example is is taken from the PHP Manual:

$d = dir("/etc");
echo "Handle: ".$d->handle."<br>\n";
echo "Path: ".$d->path."<br>\n";
while (false !== ($entry = $d->read())) {
    echo $entry."<br>\n";
}
$d->close();

You should be able to put the $entry values within an array, and create your index that way.

is there a quick way to find the directory that the php file is in? I don't want to have to change the $d = dir('blah/blah/blah/blah...") line everytime.

😃 I figured it out! getcwd()!! 😃

$d = dir(getcwd()); 
echo "Handle: ".$d->handle."<br>\n"; 
echo "Path: ".$d->path."<br>\n"; 
while (false !== ($entry = $d->read())) { 
    echo $entry."<br>\n"; 
} 
$d->close();

how can I use strstr() to check for "this" or "that"? I want it to find "jpg" and "gif" suffixes...

then

putting the results into an array is giving me problems. How can I number the entries in the array?

and

instead of saying "a = a + 1" can I use a++?

$d = dir(getcwd()); 
a = 0;
while (false !== ($entry = $d->read())) { 
  if (strstr($entry, 'jpg')){
    galArr$[a] = $entry;
    a=a+1;
  }
} 
$d->close();

It should be $a and yes you can do $a++.

You actually don't need the $a variable.

Revised code.

<?
$d = dir(getcwd()); 
while (false !== ($entry = $d->read())) { 
  if (strstr($entry, '.jpg')){
    $galArr[] = $entry;
  }
} 
$d->close();
?>

How do I verify that there is something stored in an array?

do { ... } while $array[] =! "";

this doesn't work (obviously)

[HalfaBee]

Try this

is_array( $galArr )

I got the error
Parse error: parse error, unexpected T_STRING, expecting '(' in /home/lundyar/public_html/max/galleries/digital/gallery.php on line 65

<?
$d = dir(getcwd());  

while (false !== ($entry = $d->read())) {  

  if (strstr($entry, '.jpg')){ 
    $galArr[] = $entry; 
  } 
}  

$d->close(); 

do {
  echo "found one!<br>";
} while is_array($galArr);
?>

[HalfaBee]

Try this

if( is_array( $galArr ) )
echo "found ".count($galArr).' jpgs';
