Pragmatism in the real world
In one project that I'm working on, I'm using Twig and needed to format a date received from an API. The date string received is of the style "YYYYMMDD", however date produced an unexpected output. Consider this: {{ "20141216"|date('jS F Y') }} creates the output: 20th May 1976 This surprised me. Then I thought about it some more and realised that the date filter is treating my date string as a unix timestamp. I investigated… continue reading.
I regularly deal projects that target SQL Server, but mostly develop against MySQL to avoid having to run a full Windows stack locally all the time. One of the nice things about PHP with DBAL and Migrations is that the database is pretty well abstracted from my code. Of course, this means that I don't target any of the specialist features, but for these projects, this hasn't been an issue. To convert data from SQL… continue reading.
Let's say that you have an admin form where the user can enter JSON and you'd like to validate that the JSON parses before allowing the user to submit. To do this, you can use the rather excellent jsonlint project by Jordi Boggiano. Obviously, add it via Compser :) Usage is simple: use Seld\JsonLint\JsonParser; use Seld\JsonLint\ParsingException; $parser = new JsonParser(); $result = $parser->lint($json); if ($result instanceof ParsingException) { // $json is invalid JSON } We… continue reading.
Shortly after writing my last post, it crossed my mind that it would be nice if I could autocomplete the targets in my Phing build file on the command line. In order to do this, I read Buddy Lindsey's Quick and Dirty Write Your Own Bash Autocomplete and made it do what I needed! Start by creating a new bash completion file in the bash_completion.d directory. This file needs executable permission. This directory can usually… continue reading.
Following on from my last post, here's a few other Phing things that I've found helps me. Hiding targets from Phing -l I have a number of dependent targets in my build.xml that I don't want listed when I run phing -l. The easiest way to do this is to add the hidden="true" property to the targets I want to hide: <?xml version="1.0"?> <project name="buildfile" default="foo"> <target name="foo" depends="bar,baz" /> <target name="bar" hidden="true"> <!– tasks… continue reading.
Now that I've started using migrations, I've discovered a minor irritant. I run this project on a Vagrant VM and have discovered that I keep forgetting to ssh into the vagrant box before running the migrations script. The obvious solution is to automate this and I decided to use Phing to do so. Firstly, I needed to install the PHP ssh2 extension: $ brew install libssh2 $ sudo pecl install pecl.php.net/ssh2-beta I'm on OS X,… continue reading.
I've just come across Andy Baio's Middling post and this bit really resonated with me: Twitter and Waxy Links cannibalized all the smaller posts, and as my reach grew, I started reserving blogging for more "serious" stuff — mostly longer-form research and investigative writing. From around September 2013, I found that I was in this situation. I was only posting here once or twice a month, mainly as I felt that I should only blog… continue reading.
Shortly after starting to use Doctrine Migrations as a standalone tool in my project, I came across this error message: Unknown database type bit requested, Doctrine\DBAL\Platforms\MySqlPlatform may not support it. This means that I have a column in my database of type bit which is used for booleans in SQL Server, but confuses the MySQL platform as it's not a default mapping. To support this, you need to modify the database connection's Platform object to… continue reading.
I have a client that requires me to use a VPN when connecting to their servers. I use OS X's built in L2TP VPN to connect, but don't want all my traffic going that way. To do this, I unchecked the Advanced VPN setting "Send all traffic over VPN connection" in the Network preferences and then created the file /etc/ppp/ip-up like this: sudo touch /etc/ppp/ip-up sudo chmod 755 /etc/ppp/ip-up The file itself is a bash… continue reading.
My current project has reached the point where a good migrations system is required. As I'm targeting two different database engines (MySQL and MS SQL Server) and we're already using DBAL, it made sense to use Migrations from the Doctrine project. To do this, I updated my composer.json with the following require statements: "doctrine/migrations": "1.0.*@dev", "symfony/console": "~2.5" in order to install Migrations and also Symfony console component so that I can run it from the… continue reading.
