Access information about a local file? PHP comes with a range of functions to help you obtain information about a file. Solution In the following example, we use a number of handy functions: ■ file_exists, to check whether the file exists ■ is_file, to check the file is indeed a file and not a directory ■ is_readable, to check whether the file can be read ■ is_writable to check whether the file can be written to ■ filemtime to check the date and time at which the file the file was last.
Modified ■ fileatime to find the date and time the file at which was last accessed ■ filesize to check the file’s size We also wrap the result in some custom code to make it more readable: fileInfo.php (excerpt) = 1073741824) { $size = number_format(($size $unit = 'GB'; } else if ($size >= 1048576) { $size = number_format(($size $unit = 'MB'; } else if ($size >= 1024) { $size = number_format(($size $unit = 'KB'; }.
