Im just using my imagination here but could you do the following since php reads up to down?

would this run?

$quote = "The dog ran";

$leng = strlen($quote):

$leng = $value

substr($value(0, 11));

echo $value

I don't know what you are trying to do but did you declare $value somewhere else before you assigned it to $leng? If not that will most likely throw an error because you are trying to assign a variable that hasn't been declared.

Hi Seth,

I'm unsure of what you are wanting to do, but here is what I think you were trying to do. It looks like you were trying to pass the $quote variable to $leng to get the length of the string. Then set $value = to Length and run them both through the substr function.

Check out the code example I did below. I think it should help. 

//Set the quote variable 
$quote = "The dog ran";

//I am getting the length of the $quote variable here.(returns 11)
$leng = strlen($quote);

//Running the quote variable through the substr function starting at position 0 then going to the full length of the variable which is set by the $leng variable. 
$value = substr($quote, 0, $leng); 

echo $value;

I hope this helps. Please let me know if you have any questions.

This code will throw an error as you haven't declared a value for $value, unless you have declared value prior to this code?

$value has been declared as the variable $leng higher up the code.

<?php

$quote = "The dog ran";

$leng = strlen($quote);

$value = $leng;

echo substr($value,0, 11);
echo "<br>";
echo $value;

?>

You typed little bit wrong in PHP, I guess that you were a bit hurry :smile: :sweat: when you call substr it will return 11 and when you call value it will also return 11

Btw. PHP doesn't read up to down but I think I understand what you mean :smile:

let me know if I have missunderstood :)
