Create PHP array from MySQL column

Question

mysql_fetch_array will give me an array of a fetched row. What\'s the best way generate an array from the values of all rows in one column?

Answer 1

Loop through the result:

$result = mysql_query(...);
$data = array();
while ($row = mysql_fetch_array($result)) {
    array_push($data, $row["columnyouwant"]);
}

Answer 2

// I'm using this for years and it works very good !! it's easy and logic
$translate = array();

while ($row = mysql_fetch_assoc($result))
  {
      $cullomnkey = $row['translshort']; // is what you want the key to be 
      $translate[$cullomnkey] = $row[$language]; // this is the key and the value in the array 
  }

Answer 3

you could loop through the array, and create a new one, like so:

$column = array();

while($row = mysql_fetch_array($info)){
    $column[] = $row[$key];
//Edited - added semicolon at the End of line.1st and 4th(prev) line

}

Answer 4

If you use PDO instead of php-mysql the return value of PDO::query() implements the Traversable interface, meaning you can use it e.g. with foreach() (unlike the mysql result resource you get from mysql_query).

foreach( $pdo->query('SELECT x,y,z FROM foo') as $row ) {

And in case this does not suffice and you really, really need an array (i.e. get_class($x)==='Array'), there's the fetchAll() method.

Answer 5

If none of the above work, try:

while( $row = mysqli_fetch_assoc( $result)){
     $array[] = $row['id'];
}

mysql_fetch_assoc is deprecated.

Answer 6

There is no function to do this using the mysql extension, you can do this:

$result = array();
while ($row = mysql_fetch_array($r, MYSQL_NUM)) {
    $result[] = $row[0];
}

It is apparently marginally faster to fetch the columns in a numerically indexed array, and there is no real benefit here to having the associative array format.
