PHP PDO bindParam 陷入了 foreach
我有一个这样的循环:
foreach($Fields as $Name => $Value){$Query->bindParam(':'.$Name, $Value, PDO::PARAM_STR);}
没什么复杂的.但是,每个值都设置为数组中的最后一个 ($Fields
).
我该如何解决?
解决方案然而,感谢这个 伙计们.我发现您需要在之前使用 &
通过引用传递值:
foreach($Fields as $Name => &$Value){$Query->bindParam(':'.$Name, $Value, PDO::PARAM_STR);}
这让我发疯了.
来自 PHP.net 的实际报价:

这有效(参考 $val):
&$val){$sth->bindParam($key, $val);}?>
<块引用>
这会失败($val by value,因为bindParam需要&$variable):
$val) {$sth->bindParam($key, $val);}?>
I had a loop like that :
foreach($Fields as $Name => $Value){
$Query->bindParam(':'.$Name, $Value, PDO::PARAM_STR);
}
Nothing complicated. However, each value was set to the last one in the array ($Fields
).
How can I fix that ?
解决方案However, thanks to this guys. I found out that you need to pass the value by reference with a &
before like that :
foreach($Fields as $Name => &$Value){
$Query->bindParam(':'.$Name, $Value, PDO::PARAM_STR);
}
This was driving me nuts.
Actual quote from PHP.net :

This works ($val by reference):
<?php
foreach ($params as $key => &$val){
$sth->bindParam($key, $val);
}
?>
This will fail ($val by value, because bindParam needs &$variable):
<?php
foreach ($params as $key => $val) {
$sth->bindParam($key, $val);
}
?>
