Join David Powers for an in-depth discussion in this video Generating the thumbnails, part of Code Clinic: PHP.
To generate the thumbnails…we need to include the class definition…in our main script.…That's find underscore crop dot PHP…but before we do that,…let's get rid of echo ratio at the bottom of the script.…We don't need that anymore.…Then at the top require once.…It's foundation PHP, image handling,…scale dot PHP.…
We can import the class with the use operator.…That will allow us to refer simply to scale…rather than using the fully qualified name…and name space.…Use foundation PHP backslash image handling scale.…Notice that I'm using backslash…as they are very important.…It's not a Windows convention.…This is the correct directory separator…in PHP name spaces on all operating systems.…The scale class uses image flip…that requires a minimum of PHP 5.5.…
So I think it's a good idea to define a constant…to control the use of flip…based on the current version of PHP…that's running in the server.…So let's get the version.…We'll store that as version.…It's just the PHP version function…then we can have a conditional statement…
David introduces challenges and provides an overview of his solutions in PHP. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
