通过PHP GET传递布尔值 [英] Passing a boolean through PHP GET

问题描述

很简单的问题在这里，但不知道答案。我可以通过获取布尔变量吗？例如：

  http://example.com/foo.php?myVar=true 
  
 
 $ b 
然后我有
 
 
  $ hopefullyBool = $ _GET ['myVar']; 
  
是 $ hopefullyBool 一个布尔值或字符串？我的假设是这是一个字符串，但有人可以告诉我吗？谢谢 
 
解决方案
所有GET参数都是PHP中的字符串。为了得到布尔类型，传递值为 true 或 false ，例如 0 或 1 ，然后使用： 
 
 
  $ hopefullyBool =（布尔）$ _ GET ['myVar']; 
  
如果您想传递字符串 true 或 false 然后： 
 
 
  $ hopefullyBool = $ _GET ['myVar'] =='真'？真假; 
  
甚至更好： 
 
 
  $ hopefullyBool = filter_var（$ _ GET ['myVar']，FILTER_VALIDATE_BOOLEAN）; 
  
 
Pretty simple question here, not sure the answer though. Can I pass a boolean variable through get? For example:
http://example.com/foo.php?myVar=true
then I have
$hopefullyBool = $_GET['myVar'];
Is $hopefullyBool a boolean or a string? My hypothesis is that it's a string but can someone let me know? Thanks
解决方案
All GET parameters will be strings in PHP.  To get the type boolean, pass as something that evaluates to true or false like 0 or 1, then use:
$hopefullyBool = (bool)$_GET['myVar'];
If you want to pass string true or false then:
$hopefullyBool = $_GET['myVar'] == 'true' ? true : false;
Or even better:
$hopefullyBool = filter_var($_GET['myVar'], FILTER_VALIDATE_BOOLEAN);
