Single Result from Database by using mySQLi, in case you need just a single value $row = $result->fetch_row(); $value = $row[0​];. Below are complete examples for different use cases  Single Value Mysqli . Posted by: I am trying to write a function that will check for a single value in the db using mysqli without having to place it in an array


The mysql extension could do this using mysql_result, but mysqli has no equivalent function as of today, afaik. It always returns an array.

If I didn't just create the record, I do it this way:

$getID = mysqli_fetch_assoc(mysqli_query($link, "SELECT userID FROM users WHERE something = 'unique'"));
$userID = $getID['userID'];

Or if I did just create the record and the userID column is AI, I do:

$userID = mysqli_insert_id($link);

How to pull out a single record in MySQLi and in Procedural with , And you want to pull a single record, for example the record that has a student id number of 219002991. How can I link other tables with PHP and a procedural MySQL or MySQLi database? Convert 1 row resultset to key value pairs. The subquery returns a single value: the average list price in the PRODUCT table. The outer query retrieves all rows from the PRODUCT table that have a lower list price than the average list price. In the original SQL standard, a comparison could have only one subquery, and it had to be on the right side of the comparison.


Always best to create the connection once at the beginning and close at the end. Here's how I would implement your function.

$mysqli = new mysqli();
$mysqli->connect(HOSTNAME, USERNAME, PASSWORD, DATABASE);

$value_1 = get_value($mysqli,"SELECT ID FROM Table1 LIMIT 1");
$value_2 = get_value($mysqli,"SELECT ID FROM Table2 LIMIT 1");

$mysqli->close();

function get_value($mysqli, $sql) {
    $result = $mysqli->query($sql);
    $value = $result->fetch_array(MYSQLI_NUM);
    return is_array($value) ? $value[0] : "";
}

PHP mysqli fetch_row() Function, The fetch_row() / mysqli_fetch_row() function fetches one row from a result-set Return Value: Returns an array of strings that corresponds to the fetched row. You can use same SQL SELECT command into PHP function mysqli_query(). This function is used to execute SQL command and later another PHP function mysqli_fetch_assoc() can be used to fetch all the selected data. This function returns row as an associative array, a numeric array, or both.


Here's what I ended up with:

function get_col($sql){
  global $db;
  if(strpos(strtoupper($sql), 'LIMIT') === false) {
    $sql .= " LIMIT 1";
  }
  $query = mysqli_query($db, $sql);
  $row = mysqli_fetch_array($query);
  return $row[0];
}

This way, if you forget to include LIMIT 1 in your query (we've all done it), the function will append it.

Example usage:

$first_name = get_col("SELECT `first_name` FROM `people` WHERE `id`='123'");

Even this is an old topic, I don't see here pretty simple way I used to use for such assignment:

you can assign directly more variables, not just one and so you can avoid using arrays completely. See the php function list() for details.
