Connect to my database with PHP - php

Question

I want to connect my HTML page to my database but I”m not getting it not sure why. What’s wrong with the code?
<?php
$con = mysqli_connect("localhost","root","","sibd02");
$query = sprintf("SELECT*FROM fornecedor ",
$result = mysql_query($query);
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
mysqli_close($con);
?>

Answer 1

There are lots of issues with your code. Here is my cleaned up version of your code which should work:
// Set the connection or die returning an error.
$con = mysqli_connect("localhost", "root", "sibd02") or die(mysqli_connect_errno());
// Set the query.
$query = "SELECT * FROM fornecedor";
// Run the query.
$result = mysqli_query($con, $query) or die(mysqli_connect_errno());
// Print the result for initial testing.
echo '<pre>';
print_r($result);
echo '</pre>';
// Free the result set.
mysqli_free_result($result);
// Close the connection.
mysqli_close($con);
So let’s look at your original code with notes below on each issue:
$con = mysqli_connect("localhost","root","","sibd02");
$query = sprintf("SELECT*FROM fornecedor ",
$result = mysql_query($query);
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
mysqli_close($con);
First this line $query = sprintf("SELECT*FROM fornecedor ", is incorrect syntax in PHP. And the sprintf is not needed.
Then your MySQL query would fail because it has it’s own syntax error: SELECT*FROM fornecedor That SELECT*FROM should have spaces like this SELECT * FROM.
Then you are using mysqli_connect for the connection but then using mysql_query for the query. Those are two 100% different functions in different classes. Mixing them like this will never work.

Mixing MySQL and MySQLi won't work. You can simply do this:
<?php
/* ESTABLISH CONNECTION */
$con=mysqli_connect("localhost","root","","sibd02");
if(mysqli_connect_errno()){
echo "Error".mysqli_connect_error();
}
$query = "SELECT * FROM fornecedor";
$result = mysqli_query($con,$query); /* EXECUTE QUERY */
/* IF YOU WANT TO PRINT THE RESULTS, HERE IS AN EXAMPLE: */
while($row=mysqli_fetch_array($result)){
echo $row['column']." ".$row['column2']." ".$row['column3']; /* JUST REPLACE THE NECESSARY COLUMN NAME */
} /* END OF WHILE LOOP */
mysqli_close($con);
?>
