Port php mysql scripts to php 7.0 from 5.x version

2018-04-23 2 min read Learning

Recently I got a script or series of scripts that were written for PHP 5.6x and hence used mysql_connect which as you know by now does not work with PHP 7.0. Since there were number of scripts, I thought it would be waste of time to change them manually and wrote a script to fix them. If you have similar situation then probably this few lines could help you.

Since my scripts did not use all the functions so I did not put the sed commands for all of them but you get the idea 🙂
