while ($lisa=readdir($ava)){
if ($lisa !="." && $lisa !="..") {
$files[]=$lisa;
echo '<tr><td><img src="failid/'.$files[$i].'" height="150" width="200"></tr></td>';
$i=$i+1;
}
}
closedir($ava);
?>
It works, but I dont understand it, maybe someone can explane? |
$ava is handle created with the opendir function that contains the path to where the pictures are stored, the script then loops through the directory using checking to make sure the file string is not either of the dots, then it echos a formated text string with the array, the method used is unnecesary this is a better example
PHP Code:
<?php
$dir = opendir('/path/to/pictures/');
$i = -1;
while($file = readdir($dir))
{
if($file != "." && $file != "..")
{
echo '<tr><td><img src="failid/'.$files[++$i].'" height="150" width="200"></tr></td>';
}
}
closedir($dir);
you could ofcourse use the object oriented method using dir() or glob() as wildhoney is so fond of. |
