Okay people, I got it.
I commented out the //echo ($randomPosition)
Thank you so much for your help!

I'm really not sure what to change. Maybe echo $randomPosition? But that expression should echo one letter between paramaters 0 and 5...
-
Okay, so it finally printed a letter. Yay!
But it also prints a random number...The lesson requires me to print a letter only.

This is what it last gave me.

I need a simpler code. I am a beginner and I'm trying to print a random letter of my name for the first time.
This should work, right?
$myName = "Alison";
$randomPosition = rand(0, 5);
substr($myname, $randomPosition, 1)
echo $randomPosition; -
This is what I have now but it still doesn't work...It prints Random letter from Alison: 'Alison'.
$myName = "Alison";
$randomPosition = rand(0, 5);
echo "Random letter from $myName: 'Alison'"; -
Thanks as well, Barand!
I'm having trouble printing a random (or letter character) from my name with this source code:
$myname = "Alison";
$partial = substr($myname, 0, 5);
print rand(0, 5); -
Thanks Psycho, that helped!
-
Sorry, "Alison" has only 5 letters. I meant to ask, shouldn't letter "n" be at position 5? But why does it start from right to left at position -1?
Why doesn't it start at position 0?

Hi there,
I'm learning how to code on CodeAcademy. In one of the lessons it says that substr() treats character in a string as a zero-indexed array, and that the first letter of my name "Alison" is at position zero and the last letter at position -1. Why is my last letter name at position -1? Shouldn't it be at position 6?
I'm trying to print a random letter from my name with this code. So far I wasn't able to.
$myname = "Alison";
$partial = substr($myname, 0, 3);
print rand(a, n);
Any advice would be appreciated...
Regards,
ComputerColumbus

Hell Valendor,
I added the double or single quotes. It still doesn't work. It has issue with line 1 ---> red = "exciting";
Hansford,
I tried adding at the bottom: $red = false; It's supposed to stop the loop, right? It still doesn't work.

Hi,
I'm learning PHP on CodeAcademy and for one of the lessons, I'm supposed to create my very own do/while loop. Here it is:
<?php
$red = exciting;
do {
echo "<p>It's $red to be red.</p>";
} while ($red == exciting);
?>Not sure why it's not going through. It keeps giving me an error. Can you please help?
Best regards, ComputerColumbus

I'm new to PHP. I first started my computer science endeavour a few months ago on CodeAcademy. At the moment I hold the basics of HTML and CSS but PHP is whole new story! Definintely a lot more going on. Nevertheless, I look forward to this challenge!
I joined <? PHP Freaks to learn and help others. See your around the PHP!

I'm trying my best, especially since I'm learning on CodeAcademy! Unfortunately, their idea of learning is to push you into new topics. This excercise was slightly ahead of my knowledge. I'm also reading Paul Hudson's PHP ebook. It's steadier and goes more into detail.
However, it is amazing how much I've been learning on this forum!
