How to count lines from a form?

[andy.z]

I'm having trouble working this out ...

Is there a simple way to count how many lines are returned in
$_POST['myTextArea']

When I look at the $_POST all I see is one line yet there are three.
I assume something is being interpreted differently depending on how I
view it.

Is there a simple funtion for this or can someone tell me how to work it
out please?

Thanks

Hey,

This should do the trick,

$lineCount = count( explode( "\n" , $_POST['test'] ) );

where 'test' is the nameof the textarea field

Do you reallly have three lines in your textarea, that it three bits of text
seperated by \n (the enter key)? Or, is your textarea simply word-wrapping
the text onto three "visible" lines?

If you want to be precise, you should `trim` your result first to
check to see if any value was passed. `explode` will always return an
array of length 1, even if the string parameter is empty (or even
NULL):

<?php
$string = "Hello world" ;
echo count( explode( "\n" , $string ) ) ; // "1"
$string = "" ;
echo count( explode( "\n" , $string ) ) ; // "1", not sure if that's
what you need or not
?>

`trim` will also get rid of newlines at the end of a string -- I've
noticed that on Safari in particular, textareas seem to add newlines
regardless of where "Enter" or "Return" was hit.
