High availability read-write splitting with php-mysqlnd, MySQL Replication and HAProxy
Posted by Severalnines on Mon 08 Feb 2016 12:32 UTC

MySQL Replication is used in a variety of use cases - scale out read workloads, provide high availability and geographic redundancy, offload backups and reporting/analytic jobs. However it has a big drawback - the application needs to be able to send writes to the master only. Updating more than one master in a replication setup can result in data inconsistency and cause replication to break.

An SQL-aware load balancer like MaxScale could help here, as it could redirect SQL to the appropriate node. If you are using HAProxy and the application is written in PHP, read-write splitting is still achievable with the PHP MySQL native driver with master slave plugin (aka php-mysqlnd_ms). The driver can perform the …

How to generate text representation of an image using PHP?
Posted by Satej Sahu on Mon 08 Feb 2016 04:28 UTC
Tags:

We will learn how to convert an image to its text representation using PHP that can be used in an html page (if any such requirement arises in your application or just for fun sake :) ).


The steps followed to convert the image to text representation are:

1. Get the width and height of the image to be converted.
2. Loop through every pixel value in the image.
3. At every pixel value, find the color at that position.
4. Apply that color to a # symbol we use to represent that pixel.
5. Finally we get the text representation of the image represented by # (hashes).

Code:

<html>
    <body style="background-color: #000000;">
