1. How to debug an apache virtual host configuration?

    Once again, I have a problem with my apache virtual host configuration. (The default configuration is used instead of my specific one).

    The problem is not really the misconfiguration but how to solve it.

    Does anyone have good advice to do resolve this kind of problem quickly?

    Some more pieces of information.

    The default conf file is this one:


    NameVirtualHost *
    <VirtualHost *>
            ServerAdmin webmaster@localhost
            DocumentRoot /var/www/
            <Directory />
                    Options FollowSymLinks
                    AllowOverride None
            <Directory /var/www/>
                    Options Indexes FollowSymLinks MultiViews
                    AllowOverride None
                    Order allow,deny
                    allow from all
            ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/

  2. Composer 2, which some of your plugins seem to be incompatible with

    I tried to install an extension from the Magento market place but I got an incompatibility error...


    Installing dependencies from lock file (including require-dev)

    Verifying lock file contents can be installed on the current platform.

    Your lock file does not contain a compatible set of packages. Please run composer update.


      Problem 1

        - laminas/laminas-dependency-plugin is locked to version 1.0.3 and an update of this package was not requested.

        - laminas/laminas-dependency-plugin 1.0.3 requires composer-plugin-api ^1.1 -> found composer-plugin-api[2.0.0] but it does not match the constraint.

      Problem 2

  4. Changing PHP version with Valet and Homebrew (OSX)

    Recently, I updated the PHP on my machine to version 7.4 using homebrew for Mac OS only to then realise that one of my older projects that I still needed to maintain, made on version 7.2 would no longer work due to using depreciated PHP functions such as array_key_exists.

    The long term solution to this would be to update the project so it’s compatible with PHP version 7.4, but for the sake of time, and potential fixes that needed to go out immediately, I needed to be able to develop this project in the environment it’s running in. Fortunately, I use valet to develop all my PHP applications a tool I can only recommend for PHP developers. Valet allows you to develop PHP applications on your local machine with a much higher level of ease than I’ve found using other services such as dockers or XAMP/MAMP.

    Valet, with the use of homebrew, supports switching your system PHP version at will to any version installable via homebrew. So switching versions can be as simple as th

    How to enable HTTP Strict Transport Security (HSTS) for your site

    HTTP Strict Transport Security (HSTS) instructs web browsers to only use secure connections (https://) for all future requests when communicating with a web site. Doing so helps prevent SSL protocol attacks, SSL stripping, cookie hijacking, and other attempts to circumvent SSL protection.

  6. In Laravel 5, How to disable VerifycsrfToken middleware for specific route?

    In Laravel 5 this has changed a bit. Now you can simply add the routes you want to exclude from csrftoken verification, in $except an array of the class 'VerifyCsrfToken' (\app\Http\Middleware\VerifyCsrfToken.php):

    class VerifyCsrfToken extends BaseVerifier { protected $except = [ // Place your URIs here ]; }

    csrf_token() is empty in l5-swagger and couldn't do any request.

    I have tried to request it from the postman and it works. but in swagger, it didn't. I have taken a look from this link (Laravel 5 csrf_token value is Empty) but I still have no idea how to solve my problem.

    How can I get the csrf_token inside my l5-swagger view?


     You should try to add this in /routes/web.php

  8. Solving out of memory errors with PHP and Composer on EC2s free tier

    For one of my recent projects, I wanted to make use of the free allowance that AWS gives for SES.

    One of the conditions of the SES allowance was that your calling app needs to be hosted on EC2.

    I’ve not used EC2 before so I figured this would be a good way to dive into it.

    Whilst I would never usually install software like a composer on a production server, this was pure to test things out.

    So after signing up for AWS and creating a local ubuntu server on an EC2 t2micro instance then cloning down the project I ran composer install to come across the following message:

    composer install
    Loading composer repositories with package information
    Updating dependencies (including require-dev)
    mmap() failed: [12] Cannot allocate memory
    mmap() failed: [12] Cannot allocate memory
    PHP Fatal error: Out of memory (allocated 822091776) (tried to allocate 4096 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/Solver.php o

  9. Upgrading to PHP 7 on Amazon Linux EC2 Instance

    By now you may know that PHP 7 has been available for quite some time now coming with a number of improvements over version 5. It may be wise to upgrade to PHP7 when running for instance a WordPress using Amazon AWS where you are responsible for any upgrades.

    Also as of July 2016, Amazon officially added PHP7 to its repository so you can install it using yum. So first thing I did was create a backup image of my EC2 instance before I went on with the upgrade. Once I had my backups done and proceeded with the PHP 7 upgrade.

    Here are the steps I took in order to upgrade from PHP 5.x to 7.

    Login to your Linux instance and perform the regular system updates first

    $ sudo yum update

    Stop the running webserver

    $ sudo service httpd stop

    Remove any existing PHP packages

    $ sudo yum
