To print out or display a query in PHP, you can use the echo statement. Here's an example of how to do that:

1
2
3
4
5
6
7
8
<?php

// Define your query
$query = "SELECT * FROM users";

// Echo the query to the screen
echo $query;


In this example, the echo statement is used to print out the $query variable, which contains the SQL query that we want to display. When you run this code, the query will be displayed on the screen.

To echo a query in PHP, you can use the echo statement to display the result of the query. However, depending on the type of query and the database you are using, the specific syntax may vary.


Here's a general example of how to echo the result of a query in PHP using the MySQLi extension:

connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Define your query
$query = "SELECT * FROM table_name";

// Execute the query
$result = $mysqli->query($query);

// Check if the query execution was successful
if ($result) {
    // Fetch the rows from the result set
    while ($row = $result->fetch_assoc()) {
        // Echo the data from each row
        echo $row['column_name'] . "";
    }

    // Free up the result set
    $result->free();
} else {
    // Display an error message if the query fails
    echo "Error: " . $mysqli->error;
}

// Close the connection
$mysqli->close();
?>


In this example, the SELECT query retrieves all the rows from a table, and the while loop iterates over each row, echoing the value of a specific column (column_name). You can modify the query and column name to suit your needs.


Note that this example assumes you are using the MySQLi extension. If you are using a different database or database extension (like PDO), the syntax may differ slightly.
