Your script is completely wrong, it's normal that it doesn't work.
for($i=0;$i<4;++$i){ /* The "for" is not a good solution to list the files
and a static limit (4) is useless*/
print '<td><img src="$file"></td>'; /*you've to read within the array
$file and not put it directly*/
/*If you use the ' quote php will not write the content of the variable
$file but the string $file*/
Your script will slow down your server if within the images folder there are
alot of files and/or alot of users
are visiting your site because the file listing requires alot of resources
if compared to other solutions.
You can view my sample script to have something working
and that use less resources because it does the directory listing only the
first time
and all other page loads are from the text file that will require a really
smaller amount of time.
-------------------------------------Code--------------------------------------------
<?PHP
$imagez = array();
$folderz = array();
$dirname="images/"; /*where are located the folders*/
$webdir="images/"; /*the relative webfolder*/
$imglist=$dirname . "imglist.txt"; /*the file where to store the names of
the images*/
if( file_exists($imglist) )
{
$imagez = file($imglist); //load from file! FASTER AND LESS RESOURCES
REQUIRED
} else {
$handle = opendir($dirname);
while ($file = readdir ($handle)) {
if (is_dir($webdir.$file)) {
if ( ($file == "..") or ($file == ".") ){continue;} /*exclude current
and up folders*/
$pushfld = $webdir . $file;
array_push ($folderz, $pushfld );
/*you can use the folders array to list images within subfolders! just
think! */
}
else
{
/*the extensions are up to you ....*/
if(eregi("^.*\.jpg$|^.*\.jpe|^.*\.jpeg|^.*\.gif$|^.*\.png|^.*\.swf|^.*\.mov|^.*\.avi|^.*\.mpg|^.*\.rm$",$file)) { $pushim = $webdir . $file; array_push ($imagez, $pushim ); } /*end of if eregi*/ } /*end of else*/ } /*end of while ($file = readdir ($handle))*/ if( $fp = @fopen($imglist, "w") ) { foreach ($imagez as $arro){ fputs($fp, $arro .
