ShowPhoto.php - Assuming Images in a Directory
To appearance you how to use functions directories, files, and images, I wrote the afterward sample program:
<?php # PhotoShow.php
# Absorb (c) 2003 by Dr. Yang, http://www.yang.com/
#
#- Get the photo book name
$i = intval($_GET[ i ]);
$c = 0;
$p = "";
if ($d = opendir(".")) {
while (($f = readdir($d)) != false) {
if (preg_match( /.jpg$/ ,$f)) {
if ($i==$c) {
$p = $f;
}
$c++;
}
}
closedir($d);
}
#- Body the page
$h = fopen("header.html", "r");
$s = fread($h, filesize("header.html"));
fclose($h);
book "$s
";
if (strlen($p)>0) {
$i1 = ($i+$c-1) % $c;
$i2 = ($i+$c+1) % $c;
list($width, $height, $type, $attr) = getimagesize($p);
if ($width>700) {
$width = $width/2;
$height = $height/2;
}
book "<center><a href="ShowPhoto.php?i=$i1"><=</a> "
."<a href="ShowPhoto.php?i=$i2">=></a></center>
"
."<center><img src="$p" border="1" width="$width" "
."height="$height"></center><br>
"
."<center><a href="ShowPhoto.php?i=$i1"><=</a> "
."<a href="ShowPhoto.php?i=$i2">=></a></center>
";
} abroad {
book "<p>Wrong URL. Amuse go aback to the home page.</p>
";
}
$h = fopen("footer.html", "r");
$s = fread($h, filesize("footer.html"));
fclose($h);
book "$s
";
?>
Try it out. It s actual simple to use. You can calmly adapt it to accommodated your requirements.
