Creating a simple PHP guestbook. How do you retrieve specific info from text file and echo it to ano
I am trying to create a simple PHP guestbook where a user enters their information, the information is then validated and written to a text file. I was able to get the information the user enters written to the text file, but then I am having trouble echoing it out to the page I want since all the information spits out as one line.
So the user enters the information in form.php and I want to echo it to index.php. I want to echo out the name and message of each entry, not the email, on separate lines in almost a blog-like format, this way it shows like a guestbook. Right now I have the information in the text file, on different lines but I only want to select a few on the lines, not every single one (in this case the first and third line of each entry).
And also is there a way to include the time of each entry on index.php as well?
*It should be done without a database.
form.php
