Title: PHP 7 Compatibility Last modified: January 14, 2017 --- # PHP 7 Compatibility * [joelwolfgang](https://wordpress.org/support/users/joelwolfgang/) * (@joelwolfgang) * [9 years, 4 months ago](https://wordpress.org/support/topic/php-7-compatibility-109/) * First of all – I love your plugin! I’ve been using it for years on so many sites. Thank you for making such a versatile app for the community. * Recently, I was trying to upgrade many of my sites to a PHP 7 server and I found this really cool plugin that checks to make sure that my installs are PHP 7 compatible. And unfortunately, CF7-DB was not. Here is the raw output that it gave to me discussing why it wasn’t. Do what you like with it, but I hope you can use it to help advance this plugin. Doesn’t look too bad. * Name: Contact Form DB * FILE: /nas/content/live/mdowns/wp-content/plugins/contact-form-7-to-database- extension/phpunit/WP_Mock_Functions.php ———————————————————————————————————————————— FOUND 0 ERRORS AND 1 WARNING AFFECTING 1 LINE ———————————————————————————————————————————— 48 | WARNING | Function name “__” is discouraged; PHP has reserved all method names with a double underscore prefix for future use ———————————————————————————————————————————— * FILE: /nas/content/live/mdowns/wp-content/plugins/contact-form-7-to-database- extension/CFDBWpdbUnbufferedResultIterator.php ————————————————————————————————————————— FOUND 6 ERRORS AFFECTING 6 LINES ————————————————————————————————————————— 72 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 74 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 97 | ERROR | Extension‘ mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 100 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 122 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 124 | ERROR | Extension‘ mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead.————————————————————————————————————————— * FILE: /nas/content/live/mdowns/wp-content/plugins/contact-form-7-to-database- extension/CFDBQueryResultIterator.php —————————————————————————————————————— FOUND 13 ERRORS AFFECTING 13 LINES —————————————————————————————————————— 47 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 59 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 85 | ERROR | Extension‘ mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 87 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 114 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 121 | ERROR | Extension‘ mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 122 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 132 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 136 | ERROR | Extension‘ mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 138 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 146 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 150 | ERROR | Extension‘ mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. 152 | ERROR | Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0 – use mysqli instead. —————————————————————————————————————— * Thanks and keep up the good work!!!!
