adding to an array in a loop

[andy1979]

Hi peeps

just a quicky.
I have created an array and i want to add to the array inside a while loop is this possible?

$data = array();
while ($var=mysql_fetch_array($var2))
{
if ($var==$match)
{
//this would be where i add to the data array how i dont know yet
}
}

any ideas it would really help

It certainly is possible. Read the PHP manual entries on array types and array functions.

Yes,
that is how we do it. At least I do.

Try this

<?php

$data = array();
while ($var=mysql_fetch_array($var2))
{
    if ($var==$match)
    {
        $data[] = $var; // adds $var as next element in $data 
    }
}

echo '<pre>';
print_r( $data ); // have a look at $data array

?>

Use [] to add to the end ...

$data[] = 'blah';

... or ...

array_push($data, 'Blah');

... does the same thing.

is this possible

<?php

$data = array();
while ($var=mysql_fetch_array($var2))
{
if ($var==$match)
{
$data[] = $var => $value;
}
}

echo '<pre>';
print_r( $data ); // have a look at $data array

?>

That does not really make sense, and is probably syntactically incorrect due to the =>.

If you are trying to retrieve the result set into an array, you should use:

$data = array();
while ($row = mysql_fetch_array($var2))
{
    $data[] = $row;
}

this is the script i was trying to write

$url_extq_data = array();
	if (isset($_REQUEST)) 
		{
    	foreach($_REQUEST as $key=>$value)
			{
			// only get the data for extra questions
			$schq = "SELECT * FROM extraq WHERE programid='$programid'";
			$schr = mysql_query($schq);
			while($schrow=mysql_fetch_array($schr))
				{
				$thisqid = $schrow["id"];
				$tagit = $schrow["tagit"];
				if ($thisqid==$key)
					{
					$addq3 = "INSERT INTO extraqopt (extraqid, value, subid) VALUES ('$thisqid', '$value', '$subid')";
					$addr3 = mysql_query($addq3);
					// add data add to array ready for send
					$url_extq_data = $tagit => $value;				
					}
				}
			}
		}
