1. How Can PHP Composer Update Packages without Affecting an Application that is Running

Updated on: 2022-09-12

Package: Laravel Composer Update with Zero Downtime

Composer is a popular tool many PHP developers use to define which packages they need in their projects. The composer tool can install those packages and any other dependent packages.

When a project's packages are updated, the composer tool can retrieve the new versions and update the project environment with those new ones.

Updating a project with new package versions may take a long time if a project is complex and needs many packages with a new version.

Updating a project with the new package versions in a production environment may cause the application to break since the composer cannot update all packages simultaneously.

This package provides an alternative solution to update the new versions of packages of a project in a way that does not cause the application to break.

It creates a new project vendor directory in a working directory. In the end, this package replaces the old vendor directory with the new vendor directory that has the updated versions of the project's packages.

This package implements a decentralized chat solution that allows users of a site to chat with users of other sites without currently leaving the area they are visiting.

1109. How to Quickly Find the PHP Errors that Are Preventing Your Application from Working Correctly

Updated on: 2022-09-07

Posted on:

One of the aspects of the developer work that takes us more time is finding and fixing bugs. Sometimes a subtle bug may take us hours to discover the code that is causing the bug and correct the code.

This fact is particularly true when you develop in PHP because the PHP language is very tolerant of programmer mistakes, and subtle bugs do not make the PHP scripts stop working.

Fortunately, there are methods and tools that you use to detect those bugs faster when you can capture the PHP error messages the mistakes may cause.

Please read this short article to learn how to use the Scout Application Performance Monitoring tool to quickly determine the lines of code of a Laravel or Symfony application causing the application to trigger PHP errors that can help you locate the code that you need to fix.

1. How to Implement a Fast PHP Search Engine for Applications Written Using Laravel

Updated on: 2022-09-06

Posted on:

Blog: Vegvisir Laravel Search Indexer package blog
Package: Vegvisir Laravel Search Indexer

Laravel is a popular PHP framework that implements the Model-View-Controller (MVC) design pattern.

Application objects are stored in persistent containers using model classes. Usually, these model classes use SQL database servers to store the model objects.

This solution may be acceptable when you want to store a relatively small number of model objects in database table records.

If your application needs to store and retrieve many model objects, other types of containers do not use SQL to query the database records, so it can be faster to search the object records.

This package provides a general solution to search model class objects in different storage containers that are more suited to store a large number of model class objects, like Elastic Search and Mongo DB.

Since this package provides an interface abstraction to perform searches for model objects, it is easier to change an application to use a different storage container without changing the database code.

1. How to Create a Laravel Blog Project that Uses Markdown as Format to Write the Blog Posts

Updated on: 2022-09-01

Posted on:

Blog: Laravel Markdown Blog package blog
Package: Laravel Markdown Blog

Blogs are still a popular form of publishing content of interest to a given community.

HTML is a natural format for defining blog content because Web pages use HTML to determine the page contents.

However, certain HTML tags may be insecure to allow blog post authors to submit content because a malicious author may use specific tags to steal private information from blog visitors.

Markdown is not as powerful as HTML in rendering content, but it is undoubtedly more secure because it does not support the same kind of tags HTML supports and can be insecure.

This package implements a blog system that allows authors to edit the post content in Markdown format, and then it displays that content on Web pages using regular HTML.

1. How to Simplify Your PHP Code by Performing a PHP Complexity Analisis to Find PHP Functions with Too Many Arguments

Updated on: 2022-08-31

Posted on:

Blog: PHP Function Arguments Detector package blog
Package: PHP Function Arguments Detector

Complex PHP code is hard to maintain. In practice, if you use a complex coding style, you spend a lot of time analyzing and improving your code whenever you need to make changes.

There are several types of signs that you use a complex coding style. One of them is the way you declare your classes and functions.

For instance, if you create classes with functions with many parameters, that is a sign that you are trying to do many operations in those functions.

This package can help you to find which can be complex class functions, so you can fix them, probably splitting them into several tasks that do fewer operations.

1. How to Help Your Blog Users to Decide If They Want to Read a Post Based on The Author Feelings Using a WordPress Plugin for Sentiment Analysis

Updated on: 2022-08-30

Posted on:

Blog: WordPress Plugin Sentiment Analysis package blog
Package: WordPress Plugin Sentiment Analysis

People who send text content to the Internet often express how they feel. That is the case, for instance, when post articles on a blog.

Knowing the kind of sentiment that an author of an article is expressing can be helpful for site users to decide if they would like to read the article or not, depending on the current mood.

It may also be helpful for site moderators to decide if they should approve an article or not, depending on whether the sentiment expressed by the article author is positive or negative.

This package implements a WordPress plugin that can analyze the sentiments expressed by authors of posts, pages, and comments. This way, users and moderators may understand the author's feelings.

Blog: PHP Utility Classes package blog
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

Updated on: 2022-08-26

Posted on:

Blog: Tor Geoip Tools package blog
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.
