Title: PHP7 compatibility Last modified: November 4, 2016 --- # PHP7 compatibility * [Andy Keith](https://wordpress.org/support/users/andykeith/) * (@andykeith) * [9 years, 6 months ago](https://wordpress.org/support/topic/php7-compatibility-46/) * Hi, * We’re planning to upgrade to PHP7 soon. I’ve run the PHP Compatibility Checker on your plugin and it’s showing a couple of errors. Is there any chance you could fix these in a future release? * FILE: /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: /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: /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 in advance.
