Configure LiipImagineBundle to create thumbnails of images stored on Amazon S3 and save a cache version of them again on S3 may be really painful.
In this post I’ll try to guide you step by step in the configuration process, to have a full configured data flow to create thumbnails stored on Amazon S3 using LiipImagineBundle.
Some days ago I found myself on front o f a problem: my unit tests failed because of lack of PHP memory.
This were the tedious error:
PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 16640 bytes)
As I use CodeShip.io as continuous delivery server, I had to increase the PHP memory_limit on their systems, but… how?
A brief checklist of common things you would like to configure in your Apache webserver.
Each Mac has a built-in Apache server that runs a built-in PHP.
To upgrade it you need less than 10 minutes once you have understood all the steps needed.
The same applies also to install the last PHP 7.1 version: you only need to change the required version of PHP (see below).
Here there is a good configuration for your PHP environment. It is a good checklist to use, for example, when you update MAMP.
Lazy loading is a mechanism that make the script able to load data only when they are required to.
So, if we have to load a big graph of data, we don’t load it entirely at the start, but only when it is required for use.
This mechanism is very useful as it maintain the application performances high (if used with cause cognition!).
XCode is the development environment provided by Apple and it contains a set of tools useful for development.
One of this tools is XCode Command Line Tool that
[…] gives terminal users many commonly used tools, utilities, and compilers, including make, GCC, clang, perl, svn, git, size, strip, strings, libtool, cpp, what, and many other useful commands that are usually found in default linux installations.
To install XCode Command Line Tools, you DON’T have to first install XCode.
If you receive this error trying to install some new binaries using MAMP (for example, installing Intl PHP module), then there is a chance you’ll get this error in your Terminal:
Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable. Then, rerun this script.
This happens because you haven’t the Autoconf binaries installed.
So, let’s install the Autoconf binaries in MAMP.
Intl (Internationalization) Extension
[…] is a wrapper for » ICU library, enabling PHP programmers to perform » UCA-conformant collation and date/time/number/currency formatting in their scripts.
It is really useful, as, with it, you can, for example, manage currencies and money values in the simplest way possibile (examples at the end of this post).
It is also required by some advanced framework as Symfony to work with international values.
So, let’s install Intl PHP extension…
In MacOSX there is a default Apache + PHP server.
When you type the php command in Terminal, the PHP version used is the one shipped with the MacOSX.
But, if you install MAMP, then what you want is that the version used is the one shipped with MAMP.
So, let’s make Terminal aware of the existence of the MAMP’s PHP binaries and use them instead of the ones shipped with MacOSX.
