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

If you don't need other information in that table, you can query for only the column you need and it makes it all more easy:

$query = mysql_query("SELECT * FROM table WHERE id='$int' LIMIT 1");
$column = array();
$column  = mysql_fetch_array($query);

Answer 2

$result = mysql_query("SELECT columnname FROM table WHERE x=y");

$columnValues = Array();

while ( $row = mysql_fetch_assoc($result) ) {

  $columnValues[] = $row['columnname'];

}

Answer 3

you can do this :

        $columns = array();
        $i=1;
        while( $row = mysql_fetch_array($sql) )
           {
              $columns [$i]=$row['value'];
              $i++;
           }

Answer 4

Use a while loop to get the records and store them in an array:

$array = array();
while ($row = mysql_fetch_array()) {
    $array[] = $row['column-x'];
}

Answer 5

$query = mysql_query('SELECT * from yourTable');
function mysql_field_array( $query ) {
    $field = mysql_num_fields( $query );
    for ( $i = 0; $i < $field; $i++ ) {
        $names[] = mysql_field_name( $query, $i );
    }
    return $names;
}

$fields = mysql_field_array( $query );
$output = implode( ',', $fields );   //outputs the columns names
//echo count( $fields );  //this use if you want count of columns.
$columns = '{\"fields\":\".json_encode($output).\"}';
echo $columns; //for JSON output
