SQL echo table row error? - php

Question

I'm VERY new to SQL, I have a table called "accounts". I want to echo all account info on an HTML table, I've tried this but it didn't work? (There are the proper tags around the php code)
<?php
$query="SELECT * FROM acccounts";
$results = mysql_query($query);
while ($row = mysql_fetch_array($results)) {
echo '<tr>';
foreach($row as $field) {
echo '<td>' . htmlspecialchars($field) . '</td>';
}
echo '</tr>';
}
?>

I think the problem is pretty obvious; you either didn't connect to your database, or your system doesn't allow the use of the mysql_ API.
Or, you tried connecting with the mysqli_ or other API (which is unknown). If this is the case; those different MySQL APIs do not intermix.
Using the mysqli_ API on my own machine produced results:
Replace the following with your own credentials:
<?php
ini_set("display_startup_errors", 1);
ini_set("display_errors", 1);
$connect = mysqli_connect("your_host", "user", "pass", "db");
if (!$connect) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
$query="SELECT * FROM acccounts";
$results = mysqli_query($connect, $query);
if($results){
while ($row = mysqli_fetch_array($results)) {
echo '<tr>';
foreach($row as $field) {
echo '<td>' . htmlspecialchars($field) . '</td>';
}
echo '</tr>';
}
}
else{
echo "Your query failed: " . mysqli_error($connect);
}
Check for errors on the query and via PHP.

http://php.net/manual/en/mysqli.error.php
http://php.net/manual/en/function.error-reporting.php
Note: Even without the <table></table> tags, it will still produce results, on a successful query.
Plus, this requires the file to be executed using a webserver with php/mysql installed and used as http://localhost as opposed to file:///, should this be the case.

Few things, First off, you need to connect to the database with the sql instance name, uid and passwd strings,
secondly
your query should be mysqli_query($connection, $query)
ie
$servername = 'yourinstance\sqlexpress';
$conndetails = ["Database" => "databasename", "UID" => 'loginid', "PWD" =>'passwd'];
$sqlconn = mysqli_connect($servername, $conndetails);
$query = "Select blah blah";
$query2 = mysqli_query($sqlconn, $query);
double check the syntax because i often get it backwards off the mark but without this setup you can't connect to the database,
PHP has to authenticate / login before it can make queries (otherwise anyone would be able to query your database)
Additional to this, you need to ensure sql is listening on the right ports (normally 1433) this is done through the sql manager (not the sql explorer).
the results are still in array format, so you need to call the specific field name.
in this case.
echo '<td>' . $field['id'] . '</td>';
should work, (this is the format i use)
while ($row = mysqli_fetch_array($query)) {
foreach ($row as $field) {
echo '<td>' .$field['id']. '</td>';
}
}
