Unable to install php-zip on server with Amazon Linux 2023 as well as unable to find.

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>
        <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>

        ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        <Directory "/usr/lib/cgi-bin">

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

    - magento/magento-composer-installer

I ran into this error when doing a

pecl install imagick

 on a Mac.

$ pecl install imagick
[...]
checking for pkg-config... no
pkg-config not found
configure: error: Please reinstall the pkg-config distribution
ERROR: `/private/tmp/pear/temp/imagick/configure --with-php-config=/usr/local/opt/php/bin/php-config --with-imagick' failed

By default, the needed pkg-config binary isn’t installed. You can install it via Homebrew.

$ brew instal pkg-config

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 the following:

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.

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?

Answer

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

Route::group(['middleware' => 'web'], function () {

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 ]; }

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

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
