Embed Directive in PHP
Here’s the translation of the Go embed directive example to PHP, formatted in Markdown suitable for Hugo:
In PHP, there’s no direct equivalent to the embed
directive found in Go. However, we can achieve similar functionality using PHP’s built-in file handling functions. Here’s how we can replicate the behavior:
In this PHP version:
We define a
readFile
function to read the contents of a single file. This is used to replicate the behavior of embedding a single file.We use this function to read
single_file.txt
into both a string ($fileString
) and a byte string ($fileByte
). In PHP, there’s no distinction between string and byte string, so both variables will contain the same data.We define a
readFolder
function that uses theglob
function to find all files with a specific extension in a folder. This replicates the behavior of embedding multiple files.We use this function to read all
.hash
files from thefolder
directory into an associative array.We then retrieve and print the contents of specific files from this array.
To run this example, you would need to set up the folder structure and files as follows:
Then you can run the PHP script:
Note that unlike the original example, this PHP version reads the files at runtime rather than embedding them at compile time. PHP, being an interpreted language, doesn’t have a compile step where files could be embedded into the binary.
