newbie foreach() question

[mzanimephp]

Hi, how do I say in PHP

foreach(file in "blah" ($id) directory) output this line of code:
<a href="javascript:changePhoto(1)"><img src="$id/1.jpg" width="45" height="45" hspace="2" border="0" alt=""></a>

and add one to the"changePhoto(1)"><img src="$id/1.jpg" each time.

I know how to do the foreach part... but how do I tell it to count all the files within a given directory?

[Strings]

This can count the total amount of files in a specified directory:

$handle=opendir('/path/to/directory');
$fileCount=0;
while($file=readdir($handle))
{
 if($file != '.' && $file != '..')
 {
  $fileCount+=1;
 }
}

You can then use the total value of $fileCount in a for loop to name the files for your links. The if statement can be modified so it it only counts files that end in .jpg.

Excuse the formating in this code, I'm typing this directly into the browser, and tab does not work.

$dirhandle = opendir ("/path/");

while (($filehandle = readdir($dirhandle)) !== false)  //This will cause the program to loop until all files and directories are read from the dir
{
if (!is_dir ($filehandle) //Make sure that we're only counting files
{
$count++;
echo "a href='java script:changePhoto($count)'><img src='$id/$count.jpg' width='45' height='45' hspace='2' border='0' alt=></a>";
}
}

thats great, but I forgot it has to insert a <br /> after every 6 instances of the loop. 🙂

$dirhandle = opendir ("/path/");
$count=0;
while (($filehandle = readdir($dirhandle)) !== false)  //This will cause the program to loop until all files and directories are read from the dir
{
	if (!is_dir ($filehandle)) //Make sure that we're only counting files
	{
		$count++;
		$br='';
		if($count % 6 == 0) $br="<br />";
		echo "a href='java script:changePhoto($count)'><img src='$id/$count.jpg' width='45' height='45' hspace='2' border='0' alt=></a>" . $br;
	}
}

Thanks a lot man! it works like a charm. 😃 I sure wish I had "the PHP mind" so I could write small programs like this myself.

After 40 or 50 thousand lines of code, you'd be amazed what you can whip out off the top of your head 😃
