Hello
On the following script, I get this error:
Fatal error: Unsupported operand types in ... online8
The script consists of retrieving the number present in the counter field in the visits table and adding one to it...
Thank you in advance

It's strange, we learn every day even when we don't keep ourselves informed!!!!

<?php mysql_connect("sql.free.fr","****","***"); mysql_select_db("codg82"); $requete="SELECT * from visites"; $result=mysql_query($requete); $compteur=mysql_fetch_array($result); $nombre=$compteur+1; $requete1="UPDATE visites SET compteur='$nombre' WHERE compteur='$compteur'"; $result1=mysql_query($requete1); echo "We have already had $nombre visitors on the telenote service"; mysql_close(); ?> Thank you in advance

Hello
Well, here are some explanations
I suppose the excerpt below comes from var_dump($_SESSION) unless I'm mistaken
$_SESSION is an associative array that holds all the session variables
["jours"]=> &array(6)
The variable "jours" is of type array, so it basically refers to an array (hence the ampersand & before)
that contains 6 elements
[1]=> array(7)
The element "1" of the "jours" array is itself an array of 7 elements
If we write $jours=$_SESSION["jours"]
then $jours[1][1] contains an empty string which corresponds to
["jours"]=>
&array(6) {
[1]=>
array(7) {
[1]=>
string(0) ""
Now, when you write
$travail=$_SESSION['jours'];
$travail=($travail+$count);
in $travail you have an array and in $count I don't know... the bottom line is that you can't add an array with another variable because it doesn't make sense, so $travail+$count fails with your error message: unsupported operand type, which is logical since generally addition operates on numbers. D'Oh!
