PHP Image Gallery

PHP Image Gallery

This example shows how to create a simple image gallery with php. No database is required. The first file displays the galler while the second file is used to manage the php gallery images. You can view the example here, or download the entire php gallery script here.

The first block of code can be used to show the php photo gallery to the viewer. This code uses the glob() function to select files in a particular folder, which in this this case is the gallery folder. The for loop displays all the files to the viewer. The for loops stop after all images are displayed.

$files = glob("images/gallery/*.*");
for ($i=0; $i<count($files); $i++)
{
	$num = $files[$i];
	/*print "<a href='".$SERVER[PHP_SELF]."?myeditor=".$num."'>".$num."</a><br />";
	echo '<img src="'.$num.'" alt="random image" />'."<br /><br />";*/
	
	echo '<div class="image_align">
							<div class="myimage"><a href="'.$num.'" rel="shadowbox"><img alt="placeholder" height="98" src="'.$num.'" width="130"> </a></div>
						</div>';
}

Upload Code
The following block of code can be used to upload and delete photos. If an image is uploaded, it goes into the adequate directory, which in this case is the gallery folder. The image uploaded is idential to that on the pc. There is a sufficient amout of commented text that can be used to create resized jpeg images; in case you want to add that feature.
