I used the config file reader written by mvanbeek at supporting-role dot co dot uk for one of my own scripts. I have made some modifications, and turned it into a class. <? class config_reader { var $filename; var $databaseHost; var $databaseName; var $databaseUser; var $databasePassword; function config_reader () { $this->filename = './settings.conf'; $this->getSettings(); } function getSettings () { $config = file($this->filename); reset($config); foreach ($config as $line) { $line = rtrim($line); # Get rid of newline characters $line = ltrim($line); # Get rid of any leading spaces if ($line == "" || $line == "\n" || strstr($line,"#") == 1) { next($config); } else { list($key, $value) = preg_split("/\s*=\s*/", $line, 2); # split by "=" and removing blank space either side of it. $this->$key = $value; } } } } ?> Changes: - I have cleaned up the layout of the code for readability and faster execution. - I have moved the rtrim and ltrim functions to execute before the line check, to make sure the line wasn't just a space, or a comment after a space. - I changed strstr($line, "#") to strstr($line, "#") == 1 to make sure that lines with a comment after the values are not left behind. - I also changed the way preg_split assigns the results, primarily to clean up the code. - I changed the way values are assigned to the variables. For me, this works better because I only needed to get the database information from the user. If you would like a dynamic listing of variables, do the following: Remove the following lines: <? var $databaseHost; var $databaseName; var $databaseUser; var $databasePassword; ?> Add this line: (commented lines are only to provide location for new line) <? #class config_reader { #var $filename; var $settings; #ADD THIS LINE ?> Then change this line: <? $this->$key = $value; ?> to this: <? $this->settings[$key] = $value; ?> NOTE: This has not actually been executed, so their might be a small error. I don't recommend use of this script by those new to PHP, as you will need an understanding of file permissions and setting the variables in classes. ---- Manual Page -- http://www.php.net/manual/en/function.file.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58368 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58368&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58368&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58368&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58368&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58368&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58368&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58368&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58368&report=yes Search -- http://master.php.net/manage/user-notes.php
