PHP call API using either CURL or php script

This is a pretty easy job if you are used to PHP and composer I am trying to get a service working from [login to view URL] It allows you to make Microsoft Word Template files, and have software replace values, and create a PDF file. You want to do this: [login to view URL] You call this by using a curl with json data see below: curl -u username:password -H "Content-Type: application/json" -d "{\"findAndReplaceData\":[[\"%%Test%%\",\"ReplacedString\"]],\"template\":null,\"mergeSettings\":null}" -X POST [login to view URL] Or there is sample PHP in [login to view URL] I don't use Composer, so I can't figure it out. So I made a template called [login to view URL] (See [login to view URL]) Note my template variables are "<<bozo>>" and "<<color>>". In the real world I will have many more, so if you want I can use an array to store my values. I will give access to my website You will write a PHP function called [login to view URL] It will have the ability to put my data in an array You will use a sample array in your script. $template="[login to view URL]"; $bozo="clown"; $color = "red"; $outputfilename="[login to view URL]"; I only have 2 variables for this sample, but the array should allow unlimited variables Your script will then save the created PDF to [login to view URL] The PDF should have replaced the values.
