Title: wp-db.php-error Last modified: August 19, 2016 --- # wp-db.php-error * Resolved [rebeccadewinter](https://wordpress.org/support/users/rebeccadewinter/) * (@rebeccadewinter) * [17 years, 10 months ago](https://wordpress.org/support/topic/wp-dbphp-error/) * Hi. First usage of [http://domain/wp-admin/install.php](http://domain/wp-admin/install.php) results in following error: * “Fatal error: Call to undefined function preg_match() in /usr/home/domain/htdocs/ wp-includes/wp-db.php on line 288” * I could not find any solution to this. FreeBSD 6.2 MySQL version 4.1.22 PHP Version 5.2.4 * Thanks.

Also make sure you have a good set of WordPress files uploaded– even if you have to delete and reupload. * [Uploading_WordPress_to_a_remote_host](http://codex.wordpress.org/Uploading_WordPress_to_a_remote_host) * Thread Starter [rebeccadewinter](https://wordpress.org/support/users/rebeccadewinter/) * (@rebeccadewinter) * [17 years, 10 months ago](https://wordpress.org/support/topic/wp-dbphp-error/#post-779804) * This is my line 288: `if ( preg_match("/^\\s*(insert|delete|update|replace) / i",$query) ) {` * Furthermore: PHP is configured correctly as other scripts run without any errors. And: The files were uploaded for the first time- there is no re-upload. It is the German version, readme.html dated 26.4.2008 Any ideas? * [MichaelH](https://wordpress.org/support/users/michaelh/) * (@michaelh) * [17 years, 10 months ago](https://wordpress.org/support/topic/wp-dbphp-error/#post-779810) * Just downloaded the [http://de.wordpress.org/wordpress-2.5.1-de_DE.zip](http://de.wordpress.org/wordpress-2.5.1-de_DE.zip) verson and that line you are talking about is line 287, not 288, at least in that distribution. * Thread Starter [rebeccadewinter](https://wordpress.org/support/users/rebeccadewinter/) * (@rebeccadewinter) * [17 years, 10 months ago](https://wordpress.org/support/topic/wp-dbphp-error/#post-779834) * OK, I’ll download it again and make another try. * [MichaelH](https://wordpress.org/support/users/michaelh/) * (@michaelh) * [17 years, 10 months ago](https://wordpress.org/support/topic/wp-dbphp-error/#post-779841) * Forgot to recommend that you are using ASCII mode when using FTP or automatic mode if using FileZilla. * [Uploading_WordPress_to_a_remote_host](http://codex.wordpress.org/Uploading_WordPress_to_a_remote_host) * Thread Starter [rebeccadewinter](https://wordpress.org/support/users/rebeccadewinter/) * (@rebeccadewinter) * [17 years, 10 months ago](https://wordpress.org/support/topic/wp-dbphp-error/#post-779877) * Now: file you mentioned uploaded, result is different, well not really: * `Fatal error: Call to undefined function preg_match() in /usr/home/domain/htdocs/ wp-includes/wp-db.php on line 287` * Files are uploaded in correct mode, did .PHP again manually in ASCII mode to be really sure, result is the same. OK, maybe the bug is in the MySQL, therefor here is how the database was created: * ``` # mysql -u root Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 171 to server version: 4.1.22 Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql> CREATE DATABASE wordpress; Query OK, 1 row affected (0.00 sec) mysql> GRANT ALL PRIVILEGES ON wordpress.* TO "wordpress"@"localhost" -> IDENTIFIED BY "password"; Query OK, 0 rows affected (0.04 sec) ``` * Any idea? * Moderator [Jan Dembowski](https://wordpress.org/support/users/jdembowski/) * (@jdembowski) * Forum Moderator and Brute Squad * [17 years, 10 months ago](https://wordpress.org/support/topic/wp-dbphp-error/#post-779881) * A guess, but I think your PHP5 install is not complete. * If you run “pkg_info | grep php5” and don’t see pcre in the listed output then try installing the FreeBSD 6.2 package for php5-pcre. * That should include the preg functions and get you past that error. * Thread Starter [rebeccadewinter](https://wordpress.org/support/users/rebeccadewinter/) * (@rebeccadewinter) * [17 years, 10 months ago](https://wordpress.org/support/topic/wp-dbphp-error/#post-779889) * Output: * pkg_info | grep php5 php5-5.2.4_1 PHP Scripting Language php5-mysql-5.2.4_1 The mysql shared extension for php php5-pcre-5.2.4_1 The pcre shared extension for php * …after having installed php5-pcre.
