Question

Here is the code that used but return the 500 error in php version 7 and I totally screwed what to do with and could not find any documentation to do so.

<?php
// Create a new MySQL database connection
if (!$con = mysql_connect('localhost', 'root', 'password')) {
die('An error occurred while connecting to the MySQL server!<br><br>' . mysql_error());
}

if (!mysql_select_db(sample)) {
die('An error occurred while connecting to the database!<br><br>' . mysql_error());
}

// Create an array of MySQL queries to run
$sql = array(
'DROP TABLE IF EXISTS content;',
'CREATE TABLE content SELECT * FROM sample1.content'
);

// Run the MySQL queries
if (sizeof($sql) > 0) {
foreach ($sql as $query) {
if (!mysql_query($query)) {
die('A MySQL error has occurred!<br><br>' . mysql_error());
}
}
}

mysql_close($con);

?>

You are using an deprecated implementation of mysql that have been removed in php7.

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include: mysqli_query() PDO::query()
