Find what version of PHP your script requires. FremontTech has just started selling scripts online. When asked what version of PHP is required to run our scripts we didn’t have a definitive answer. We created this script to determine the PHP version, and then we took it to another level by seeking out deprecated functions. But we didn’t stop just at that. We included PHP Extensions and language constructs. We almost called it good at that, but then we wondered… how many times we used these functions. Excessive use of the same function can be degrading on performance. Monitoring how many times a function is used can help determine if a “User Created Function” can be created to reduce code and increase performance.
