Note Submitter: kermodebear -at- kermodebear -dawt- org ---- Unlike fopen(), the PDF library does NOT allow one to search for a file along the include path. Where I work, the images used for document generation are kept in an include path, which is fine for some applications, but PDFLib requires an absolute path. This small function will take a relative path to a file and search the include structure, eventually returning either the absolute path or false. <?php function get_absolute( $file ) { $include_path = ini_get( 'include_path' ); $a_paths = split( ':', $include_path ); foreach( $a_paths as $path ) { if ( is_file( $path . '/' . $file ) ) { return $path . '/' . $file; } } return false; } ?>
