note 48989 added to function.parse-ini-file

Here's a much better way of reading and writing INI files. (much fewer character restrictions, automatic comment header, binary safe, etc.) <?php /* Function to replace PHP's parse_ini_file() with much fewer restritions, and a matching function to write to a .INI file, both of which are binary safe. Version 1.0 Copyright (C) 2005 Justin Frim <phpcoder@cyberpimp.pimpdomain.com> Sections can use any character excluding ASCII control characters and ASCII DEL. (You may even use [ and ] characters as literals!) Keys can use any character excluding ASCII control characters, ASCII DEL, ASCII equals sign (=), and not start with the user-defined comment character. Values are binary safe (encoded with C-style backslash escape codes) and may be enclosed by double-quotes (to retain leading & trailing spaces). User-defined comment character can be any non-white-space ASCII character excluding ASCII opening bracket ([). readINIfile() is case-insensitive when reading sections and keys, returning an array with lower-case keys. writeINIfile() writes sections and keys with first character capitalization. Invalid characters are converted to ASCII dash / hyphen (-). Values are always enclosed by double-quotes. writeINIfile() also provides a method to automatically prepend a comment header from ASCII text with line breaks, regardless of whether CRLF, LFCR, CR, or just LF line break sequences are used! (All line breaks are translated to CRLF) */ function readINIfile ($filename, $commentchar) { $array1 = file($filename); $section = ''; foreach ($array1 as $filedata) { $dataline = trim($filedata); $firstchar = substr($dataline, 0, 1); if ($firstchar!=$commentchar && $dataline!='') { //It's an entry (not a comment and not a blank line) if ($firstchar == '[' && substr($dataline, -1, 1) == ']') { //It's a section $section = strtolower(substr($dataline, 1, -1)); }else{ //It's a key... $delimiter = strpos($dataline, '='); if ($delimiter > 0) { //...with a value $key = strtolower(trim(substr($dataline, 0, $delimiter))); $value = trim(substr($dataline, $delimiter + 1)); if (substr($value, 1, 1) == '"' && substr($value, -1, 1) == '"') { $value = substr($value, 1, -1); } $array2[$section][$key] = stripcslashes($value); }else{ //...without a value $array2[$section][strtolower(trim($dataline))]=''; } } }else{ //It's a comment or blank line.
