Some images containing spces in the file name led me to some errors when trying to determine their image size for manipulation using PHP.
Simply url encoding the string fixed this problem.
<?php
$imagePath = "some funky filename.jpg";
$imagePath = str_replace(" ","%20",$imagePath);
list($imgwidth,$imgheight) = getimagesize($imagePath);
?>
I needed to be able to access a pdf outside my document root… so I created the script below. Using just file_get_contents with an echo would just save it as the name of the script, using an $output_file variable and in the header you are able to specify what you want to save it as.
<?php
$output_file = 'outfilename.pdf';
$file = "target.pdf";
$fileDir = '../target/directory/';
$contents = file_get_contents($fileDir.$file);
header("Content-Disposition: attachment; filename=" . $output_file);
header('Content-type: application/pdf');
echo $contents;
exit();
?>
