Counting Characters in variable returned.
Posted 28 October 2006 - 04:53 PM
I'm trying to write a php echo file to go with a html form.
I need to count and show the total number of characters returned from the variables entered on the form.
Where do I insert this and do I use count() or strlen() or neither? This may be simple but I'm new to php and struggling.
Here is my php code so far - not sure if you need the code from my html form aswell.
Thanks in advance.
Your favourite book is <?php echo $_GET["book"]; ?>.<br />
Your favourite meal is <?php echo $_GET["meal"]; ?>.

method="url" in the form. I suggest using the post method, then the way to count the string length of the submitted stuff is:
<?php $fav_book = $_POST['book']; $fav_meal = $_POST['meal']; $book_length = strlen($fav_book); $meal_length = strlen($fav_meal); //then echo it echo("<p>Your favorite book is $fav_book.</p>"); echo("<p>Your favorite meal is $fav_meal.</p>"); //and use the length variables however you want, you didn't really go into detail on that ?>
plus, the count function is used to count the number of values in an array, so it wouldn't be of use here.

I am using it on a local web server - my own PC - so files are in the same place.
