In this repository, you can find a compiler, that replaces placeholders (${placeholertitle}) in the specified file (index.php).
To use the project, you just execute the index file with php.
To edit the input and output file names, just edit lines 3-5 in index.php.
$input = "template.html";
$file_replacements = "input.txt";
$output = "index.html";
IMPORTANT! You can only use one placeholder per line in the input file!
