How would I replace the elements with matching keys between $array1
and $array2 to end up with 'a,b,c,d,e,f'.
$array1 - Array ( [2] =c [3] =d )
$array2 - Array ( [0] =a [1] =b [2] =x [3] =x [4] =e [5] =>
f )
Many thanks,
Chris
you can use this code
foreach($array1 as $key =$value)
{
if(array_key_exists($key, $array2))
{
$array2[$key] = $value;
}

Cheers,
That has solved my problem...fuller snippet given below.
// Performing SQL query
dbConnect("$db");
$query = "SELECT * FROM room";
$result = mysql_query($query) or die("Query failed : " .
mysql_error());
$query_booking = "SELECT * FROM booking WHERE weeknumber =
$weeknumber";
$result_booking = mysql_query($query_booking) or die("Query failed :
" . mysql_error());
while($rowRoom = mysql_fetch_array($result, MYSQL_ASSOC)) {
$timetable = explode(',', $rowRoom['timetable']);
}
while($rowBooking = mysql_fetch_array($result_booking, MYSQL_ASSOC)) {
$period = $rowBooking['period'];
$teacher = $rowBooking['teacher'];
$booking[$period] = "$teacher";
}
foreach($timetable as $key =$value)
{
if(array_key_exists($key, $booking))
{
$int = $key -1;
$timetable[$int] = $booking[$period];
}
}
