警告：条件分配 [英] Warning: Assignment in condition

问题描述

有一件事总是欺骗我，当检查我的php脚本的问题，我得到警告bool分配：条件分配，我得到他们很多。
例如：

One thing that has always bugged me is that when checking my php scripts for problems I get the warning "bool-assign : Assignment in condition" and I get them a lot. e.g.:

$guests = array();
$sql = "SELECT * FROM `guestlist`";
$result = mysql_query($sql);
while($row = mysql_fetch_assoc($result))
    $guests[] = $row['name'];

有不同的方法来获取多个或所有行到一个对象或数组？

Is there a different way to get multiple or all rows into an object or array? Or is there nothing wrong with this method?

推荐答案

尝试这样做：

$guests = array();
$sql = "SELECT * FROM `guestlist`";
$result = mysql_query($sql);
while(($row = mysql_fetch_assoc($result)) !== false)
    $guests[] = $row['name'];

我相信php是警告，因为$ row = mysql_fetch_assoc（$ result）不返回布尔值。

I believe php is warning because of the $row = mysql_fetch_assoc($result) not returning a boolean.
