Blog: Laravel A1 PDF Sign package blog
Package: Laravel A1 PDF Sign

PDF is a popular format for generating documents that users can view or print.

Anybody can alter a PDF document using editing tools. In some cases, the original author does not want that the document is changed.

Certificates can be used by the PDF document author to digitally sign a document to assure that the original document is intact when the users view it.

The PDF document viewer programs can check the digital signature contained in a document to verify if it is still intact.

This package provides a pure PHP solution to sign existing PDF documents with x509 digital signatures.

1. How to Improve Your Productivity Using Laravel Macro to Build Forms that Have Complex Select Inputs

Updated on: 2022-09-27

Posted on:

Blog: Laravel Macro Example package blog
Package: Laravel Macro Example

A macro is an abbreviated form to represent information that may be long.

Macros can help save time for developers that need to write code for the different parts of their applications.

This package provides an example of how to use macros in Laravel applications by showing how to create a macro class that generates HTML for options of a form select input that has many options, for instance, a list of supported banks.

This macro class can save a lot of time for developers that need to insert the same type of form select input in the output of their applications' Laravel view templates.

1. How to Implement a PHP Hash Generator That is Simple Fast in Pure PHP

Updated on: 2022-09-26

Posted on:

Blog: PHP Murmurhash package blog
Package: PHP Murmurhash

Hashing is an operation that computes a value from a string of data.

Hashing operations help check the integrity of data that may be transmitted between a source computer and a destination computer to detect data transmission failures caused by external interferences.

In environments in which security is an important aspect, developers should use cryptographic hashing algorithms to detect malicious alteration of data by people with bad intentions.

In environments where security is not essential due to the low risk of alteration of data by bad-intentioned people, developers can use non-cryptographic algorithms.

Such algorithms do not require so much CPU processing power and can run faster.

Murmurhash is a non-cryptographic algorithm.

This package provides a pure PHP implementation of the Murmurhash algorithm. Therefore it does not require that particular cryptography PHP extensions are available to use this class.

1. How to Set or Get the PHP Types of Variables Without the Risk of Committing a Mistake When You Type the Variable Type Names

Updated on: 2022-09-23

Posted on:

Blog: PHP Type Class package blog
Package: PHP Type Class

PHP is a weakly typed language. This fact means that it allows setting the type of variable values when executing the PHP code.

Although this makes the PHP language very flexible and tolerant of the developer's mistakes, sometimes it can be hard to debug subtle bugs caused by the developer's errors.

In practice, that can mean that developers may take more time to fix subtle bugs that probably would not exist if PHP was a strongly typed language.

This package provides a solution that can help to avoid those bugs. It gives the name strings of the PHP variable types.

So, if a developer wants to use the PHP GetType and SetType functions to get or set the variable type, the developer can use this class.

So, if the developer makes a mistake in the name of a constant provided by the class, PHP will trigger an error that can make it easier to find bugs caused by typing the name of a PHP type.

1110. How to Fix PHP Errors That Affect More Your Applications By Giving Priority to the Most Important Bugs

Updated on: 2022-09-20

Posted on:

Fixing application bugs is a task that often consumes developers a lot of time, especially the step of finding the cause of the bugs. PHP error log processing tools help find the code with bugs causing the errors.

Often developers can find many errors using PHP error log processing methods and tools. If they have many errors, they have another challenge: decide which bugs they should fix first.

One good criterion is first to fix the bugs causing more PHP errors. Counting the PHP errors that appear in a PHP error log may be a task that consumes a lot of time when you do it manually. Fortunately, there are methods and tools that you use to count and sort the PHP errors that appear in PHP logs.

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 PHP application causing more PHP errors so that you can fix those frequent errors first.

1. How Can PHP Generate Noise Images Faster to Use in the Background the CAPTCHA Validation Images

Updated on: 2022-09-15

Posted on:

Blog: SimpleX Noise Algorithm package blog
Package: SimpleX Noise Algorithm

Noise is a signal that can cause certain disturbances. It is often associated with sound but can also be associated with an image.

Noise images can be helpful. For instance, you may use noise images to generate CAPTCHA validation images that may obfuscate a picture with text that the user needs to recognize.

The noise image can help obfuscate the text to make it harder for robots to recognize the text while humans may be able to identify it.

This package can generate noise data for creating noise images for CAPTCHA validation or other purposes.

It uses the SimpleX noise algorithm. This algorithm has several advantages over classic forms of generating noise like the Perlin algorithm.

For instance, the simplex algorithm requires less computing power to create noise.
