I am fairly new to PHP. I am trying to get my code to read the content of a Markdown file based on the content of GET attribute "pgid", and then output it. This:
print Parsedown::instance()->text("Testing *Markdown* with **Parsedown**")
results in the output
Testing Markdown with Parsedown
But this:
print (Parsedown::instance()->text(readfile("./".$_GET['pgid'].".md")));
with ?pgid=about and the content of about.md being Testing *Markdown* with **Parsedown**, the output is
Testing *Markdown* with **Parsedown** 39
I am unsure why I can get all of the parts to work separately, but not together.
PHP's readfile() does not return file contents, it outputs them.
What your code does, is basically this:
print readfile($filename); // The print() here is implied by readfile itself.
print (Parsedown::instance()->text(80));
Where 80 is the number of bytes read from the file.
Instead of readfile(), you'll probably want to use file_get_contents(), which does return the contents of the file.
