Converting an old project from using the mysql extension to the mysqli extension, I found the most annoying change to be the lack of a corresponding mysql_result function in mysqli. While mysql_result is a generally terrible function, it was useful for fetching a single result field *value* from a result set (for example, if looking up a user's ID).


The behavior of mysql_result is approximated here, though you may want to name it something other than mysqli_result so as to avoid thinking it's an actual, built-in function.


<?php

function mysqli_result($res, $row, $field=0) {

$res->data_seek($row);

$datarow = $res->fetch_array();

    return $datarow[$field];

}

?>



Implementing it via the OO interface is left as an exercise to the reader.

Switching from Php5 to Php7, especially if you have worked on an ongoing, long term project, it is unfortunate that there is no mysqli_result function.

So, this may be helpfull and you can call this function as you wish. I assume you do restricted search (searching for single row or few rows only).

function mysqli_result($search, $row, $field){
$i=0; while($results=mysqli_fetch_array($search)){
if ($i==$row){$result=$results[$field];}
$i++;}
return $result;} 

Simply;

$search=mysqli_query($connection, "select name from table_name where id='7'");
$name=mysqli_result($search, 0, "id"); 

Best wishes,

An "mysqli_result" function where $field can be like table_name.field_name with alias or not.
<?php
function mysqli_result($result,$row,$field=0) {
    if ($result===false) return false;
    if ($row>=mysqli_num_rows($result)) return false;
    if (is_string($field) && !(strpos($field,".")===false)) {
$t_field=explode(".",$field);
$field=-1;
$t_fields=mysqli_fetch_fields($result);
        for ($id=0;$id<mysqli_num_fields($result);$id++) {
            if ($t_fields[$id]->table==$t_field[0] && $t_fields[$id]->name==$t_field[1]) {
$field=$id;
                break;
            }
        }
        if ($field==-1) return false;
    }
mysqli_data_seek($result,$row);
$line=mysqli_fetch_array($result);
    return isset($line[$field])?$line[$field]:false;
}
?>

Extending the MySQLi_Result

<?php

class Database_MySQLi extends MySQLi
{
    public function query($query)
    {
$this->real_query($query);
        return new Database_MySQLi_Result($this);
    }
}

class Database_MySQLi_Result extends MySQLi_Result
{
    public function fetch()
    {
        return $this->fetch_assoc();
    }

    public function fetchAll()
    {
$rows = array();
        while($row = $this->fetch())
        {
$rows[] = $row;
        }
        return $rows;
    }
}

?>
