Question

I need to get a field from a mySQL database using PHP
The problem is that in my mysql panel I use this sql code:

SELECT * FROM TESTS WHERE TEST_ID=1

and I get exactly what I want (I see the row that I want to display)
But if i use this code in PHP:

<?php
$con=mysql_connect("localhost", "root", "psw")  or die("\nConnection Failed\n");

mysql_select_db("mydb")or die("\nDB Failed\n");

$query = "SELECT * FROM TESTS WHERE TEST_ID=1";
$result=mysql_query($query);

echo $result;
mysql_close($con);
?>

all I get is “Resource ID #3”

why??

Answer 1

the $result is a resource which is a link to a result set from mysql. To get the actual data you have to do something like:

$data = mysql_fetch_assoc($result);
print_r($data);

You would need to repeat the mysql_fetch_assoc() call for each row you want to retrieve, until it returns false, indicating there are no more rows, which can be done in a while loop like this:

while ($data = mysql_fetch_assoc($result)) {
    print_r($data);
}
