RE: [PHP] Trim an array?

2001-02-03 Thread PHPBeginner.com 

a simple

snip
for($i=0; $isizeof($array); $++)
$array[$i]=trim($array[$i]);
/snip

will do the trick

Subject: [PHP] "Trim" an array?


I looked through the archives and couldn't find anything on this.

I have a web form which takes 9 values to create a definition for a table
that would have up to 9 columns.

I made the table so that each form field is submitted as an array so that I
can simply step through each value and create the table definition, so:

input type=text name="tblcol[]"  (duplicated 9 times)

Now, when I submit the form the resulting array always has 9 elements and
some of those will be empty.

I would like to do error checking in case people didn't fill anything at all
so I thought using if (!count($tblcol)) { But that doesn't work since it
always has 9 elements.

Is there a way to find out if an array contains no values even though it has
elements?  Sort of like a trim() function on an array to destroy the
elements in the array that are empty.

Is it possible?

while(list($key,$value)=each($array)){
if(empty($value)) unset $array[$key];
