在我的php代码中,我从数据库中获取数据,并将数据放入特定值:
$from_db=mysql_query(" SELECT * FROM ... ");
while ($row = mysql_fetch_array($from_db)) {
$number_id[]=$row['number_id'];
...
}
现在我想在命令“while”之前添加这一行(用于其他目的):
$from_db = mysql_fetch_array($from_db);
如何更改此行:while ($row = mysql_fetch_array($from_db)) {
来处理数组而不是数据库中的原始数据?

我建议您改用PDO class。不建议使用mysql_ *函数,并且将在(远)将来弃用。
一个例子是:
//Connect to database and whatnot
//...
$PDOquery=$PDO->prepare('SELECT * FROM users WHERE id=?;');
$PDOquery->execute(array(1));
$resultArray=$PDOquery->fetchAll(PDO::FETCH_ASSOC); //Results stored as associative array in ths array.

不幸的是,有必要这样做:
$from_db=mysql_query(" SELECT * FROM ... ");
$from_db = array();
while ($row = mysql_fetch_array($from_db)) {
$from_db[] = $row;
}
foreach($from_db as $row) {
$number_id[]=$row['number_id'];
}

<?php
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();
/* Fetch all of the remaining rows in the result set */
print("Fetch all of the remaining rows in the result set:\n");
$result = $sth->fetchAll();
print_r($result);
