Package: PHP Utility Classes

Measuring the time a PHP script takes to execute allows determining if a hand is too slow and if its performance needs to be optimized.

When PHP is used to serve Web pages, the execution time must be measured from when the Web server received the HTTP request.

This package provides a class that can calculate the current script's real execution time considering the HTTP request start time.

1. How Can PHP Allow IP Address Range of Real Users by Blocking Machines Used to Perform Security Attacks

Package: Tor Geoip Tools

Sometimes Web servers that run PHP sites are attacked by several machines hosted in the same network.

One way to protect against those attacks from all those machines is to block network connections from the whole IP address range segment.

This package simplifies blocking a whole IP address range segment by generating commands to run the Linux iptables command that adds rules to stop all the IP addresses that belong to those range segments.

1. How to Use PHP Validation Type Casting to Perform Complex Form Validation with Less Code

Updated on: 2022-08-25

Blog: Formal PHP Validation Library package blog
Package: Formal PHP Validation Library

Many Web applications need to validate values entered by the users to avoid invalid values that can make the application work unexpectedly.

Usually, developers define a set of rules to validate values entered by users. In some cases, specific values need to be validate by several rules.

This package supports the concept of type casting. This concept allows the definition of rules that combine several other rules into a single rule.

This way, developers can simplify the definition of complex rules in less code than if they had to define all simple rules for each value that their applications need to validate.

Updated on: 2022-08-24

Posted on:

When you discover what parts of your applications are the slowest, you are in an excellent position to start making changes in your code that can significantly impact the application's performance.

Going through a large section of code and finding the exact lines of slow code can take too much time.

A good profiling tool can help you find the exact lines of code that make the code so slow, so you can quickly determine why the code section is so slow.

Please read this short article to learn how to use the Scout Application Performance Monitoring tool to determine the specific lines of code of a Laravel or Symfony application that are causing the application to be so slow, so you can focus your optimization work on the code changes that really can make a difference after you optimize the code.

Package: PHP Environment Variables Detection

dotenv is a popular format used by many developers to store configuration values.

It is language-independent, so applications written in different languages can easily read the files in that format.

Usually, dotenv files exist in a fixed location relative to the path of a project.

If you have multiple projects, you may need to find the path of the dotenv file to load the correct configuration file.

This package can test different paths and find the correct location based on a list of possible setups for your projects and the current HTTP host.
