PHP中传递数据遇到奇怪问题!听说标题要长!
HTML中定义的textbox如下: ↓


表单按钮提交的时候 后台接受如下: ↓


$num0 = (string)$_POST["my_test"];
$num1 = (int)$_POST["my_test"];
$num2 = intval($_POST["my_test"]);
$num3 = $num0*1;
echo $num0;
echo $num1;
echo $num2;
echo $num3;

运行后打印如下:
1 0 0 0

这是怎么回事 为什么强制类型装换1的时候 给我全都默认转为0了??????求解答

经测试,没有发现你说的问题
------解决方案--------------------
不知道LZ的编码是不是UTF-8,如果是有可能和BOM有关吧
------解决方案--------------------
将你完整的代码发上来.这是 布阔能滴.
------解决方案--------------------
我用utf-8试了下,也都是1呀。。
------解决方案--------------------
试了,还是没发现问题。。。
------解决方案--------------------
对于你这个问题我也遇到过!感觉很奇怪,当值是1的时候,用intval()和(int)$var去转换变量类型时,会把1为换位0!这是个很奇怪的问题!或许真和编码有关系,当时的编码是utf-8,不晓得gbk会不会出现这种问题!

求解决啊!!!!!!!!!
------解决方案--------------------
if($_GET["type"]){

我看你后面的代码没有传递type嘛..并且 输出 .$num2 不是 num2...

并且 addslashes 要过滤的是字符串 你给的是数组...

if($_GET["type"]){
$num1 = (int)$_POST["my_test1"];
$num2 = (int)$_POST["my_test2"];
echo $num1."-".$num2 ;
}
?>







这段代码没有任何问题,如果这段代码在你那输出的还是 不正确的,你的php版本是?

------解决方案--------------------
C/C++ code
if(!get_magic_quotes_gpc()){addslashes($_POST);addslashes($_GET);}if($_GET["type"]){$num1 = (int)$_GET["my_test1"];$num2 = (int)$_GET["my_test2"];echo $num1."-".num2 ;}<br><font color="#e78608">------解决方案--------------------</font><br>错的真多。<br>编码那里传的数组  X;<br>对数字进行了字符连接,结果肯定是字符。你可以在代码里写上:<br>$n1=3;<br>$n2=5;<br>echo $n1.'_'.$n2;<br>看看,结果肯定是3_5;<br>对于你的类型转换问题,个人猜测是HTTP的问题,以前看到过书上提到过。建议你对每个转换后的类型var_dump一下。<div class="clear">

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
