mysql_fetch_arrayすべての行を追加しますか？

Question

mysql_queryからmysql_fetch_array（）にすべての行を追加するにはどうしたらいいですか？かなりの数の行で作業できるので、できるだけ効率的にやりたいと思っています。

Answer 1

最も一般的な方法：

$rows = array(); 

while(($row = mysql_fetch_array($result))) { 
    $rows[] = $row; 
} 

as shown in the examples in the documentation.

Answer 2

<?php 

$db = new mysqli("localhost", "foo_dbo", "pass", "foo_db", 3306); 

$startTime = microtime(true); 

$result = $db->query("select * from users"); 

$users = $result->fetch_all(MYSQLI_ASSOC); // faster 

// while($row = $result->fetch_assoc()) $users[] = $row; //slower 

echo sprintf("%d users fetched in %s secs", 
    count($users), number_format(microtime(true) - $startTime, 6, ".", "")); 

$db->close(); 

?> 

EDITいくつかの実行時の統計

$users = $result->fetch_all() 

    1000 users fetched in 0.001462 secs 
    5000 users fetched in 0.005493 secs 
15000 users fetched in 0.015517 secs 
50000 users fetched in 0.051950 secs 
100000 users fetched in 0.103647 secs 

対

while($row = $result->fetch_assoc()) $users[] = $row; 

    1000 users fetched in 0.001945 secs 
    5000 users fetched in 0.008101 secs 
15000 users fetched in 0.023481 secs 
50000 users fetched in 0.081441 secs 
100000 users fetched in 0.163282 secs
