I'm cobbling together a very simple PHP script, but I can't get it to work. I'm connecting to the SQL database, but it's not retrieving the value I want. I just have a single entry in a single table in a single database. I want to retrieve that value, then add one to it.
<?php
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'root';
$dbname = 'test';
$dbtable = 'counter';
//------ DATABASE CONNECTION --------//
mysql_connect($dbhost,$dbuser,$dbpass)
or die ("Unable to connect to database");
mysql_select_db($dbname)
or die ("Unable to select database");
$test = "SELECT FIRST('count') FROM $dbtable";
?>
This button has been clicked <?php echo $test; ?> times.
EDIT: Found a solution with the aid of angelo
<?php
//parameters to set
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'root';
$dbname = 'test';
$dbtable = 'counter';
$dbcolumn = 'count';
//end of list of parameters to set
$connect = mysqli_connect($dbhost,$dbuser,$dbpass,$dbname);
if(!$connect){die("Connection error");}
$test = mysqli_query($connect,"SELECT ".$dbcolumn." FROM ".$dbtable);
$assoc = mysqli_fetch_assoc($test);
$num = $assoc[$dbcolumn];
?>
This button has been clicked <?php echo $num; ?> times.
<?php
$plus = $num+1;
//mysqli_query($connect,"INSERT INTO ".$dbtable."('".$dbcolumn."') VALUES ('".$plus."')");
mysqli_query($connect,"DELETE FROM counter WHERE count = $num");
mysqli_query($connect,"INSERT INTO counter (count) VALUES ($plus)");
?>

Why your code is not working
You're not launching your query
Warning
You're using mysql_ functions, which are deprecated. You should use mysqli_ instead.
Solution
Use this code:
<?php
//parameters to set
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'root';
$dbname = 'test';
$dbtable = 'counter';
$dbcolumn = 'col';
//end of list of parameters to set
$connect = mysqli_connect($dbhost,$dbuser,$dbpass,$dbname);
if(!$connect){die("Connection error");}
$test = mysqli_query($connect,"SELECT ".$dbcolumn." FROM ".$dbtable);
$assoc = mysqli_fetch_assoc($test);
$num = $assoc[$dbcolumn];
?>
This button has been clicked <?php echo $num; ?> times.
Please note that this code only shows the number of clicks.
To add one to this value, append the following code to the previous one:
<?php
$plus = $num+1;
$query = "UPDATE ".$dbtable." SET ".$dbcolumn."='".$plus."'";
mysqli_query($connect,$query);
?>
