( ! ) Fatal error: Cannot use isset() on the result of a function call (you can use "null !== func()" instead) in C:\Users\sanoj\Documents\NetBeansprojects\video-site\app\detect.PHP on line 45 Call Stack # Time Memory Function Location 1 0.0000 234208 {main}( ) ..\index.PHP:0
以前我的代码是
if(!defined('WAP'))
define('WAP',isset($_REQUEST['wap']) || isset($_REQUEST['wap2']) || isset($_REQUEST['imode'])|| isset($_REQUEST['html'])|| isset($_REQUEST['Android'])|| isset($_REQUEST['iphone'])|| isset($_REQUEST['IEMobile']));
if (WAP)
{
define('WIRELESS_PROTOCOL',isset($_REQUEST['wap']) ? 'wap' : (isset($_REQUEST['wap2']) ? 'wap2' : (isset($_REQUEST['iphone']) ? 'iphone' : (isset($_REQUEST['imode']) ? 'imode' : (isset($_REQUEST['IEMobile']) ? 'IEMobile' :(isset($_REQUEST['html']) ? 'html' : (isset($_REQUEST['Android']) ? 'Android' : '')))))));
我的IDE警告不要直接访问SuperGlobal $_REQUEST数组
所以我使用了以下代码
if(!defined('WAP'))
{
define('WAP',isset(filter_input(INPUT_REQUEST,'wap',FILTER_SANITIZE_STRING)) || isset(filter_input(INPUT_REQUEST,'wap2','imode',FILTER_SANITIZE_STRING))|| isset(filter_input(INPUT_REQUEST,'html','Android','iphone','IEMobile',FILTER_SANITIZE_STRING)));
}
if (WAP)
{
define('WIRELESS_PROTOCOL',FILTER_SANITIZE_STRING)) ? 'wap' : (isset(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) ? 'wap2' : (isset(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) ? 'iphone' : (isset(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) ? 'imode' : (isset(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) ? 'IEMobile' :(isset(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) ? 'html' : (isset(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) ? 'Android' : '')))))));
这是detect.PHP
<?PHP $userbrowser = $_SERVER['HTTP_ACCEPT']; if(stristr($userbrowser,'application/vnd.wap.xhtml+xml')) { $_REQUEST['wap2'] = 1; } elseif(stripos($_SERVER['HTTP_USER_AGENT'],"iPod")) { $_REQUEST['iphone'] = 1; } elseif(stripos($_SERVER['HTTP_USER_AGENT'],"iPhone")) { $_REQUEST['iphone'] = 1; } elseif(stripos($_SERVER['HTTP_USER_AGENT'],"Android")) { $_REQUEST['Android'] = 1; } elseif(stripos($_SERVER['HTTP_USER_AGENT'],"IEMobile")) { $_REQUEST['IEMobile'] = 1; } elseif(stristr($userbrowser,'DoCoMo/' || 'portalmmm/')) { $_REQUEST['imode'] = 1; } elseif(stristr($userbrowser,'text/vnd.wap.wml')) { $_REQUEST['wap'] = 1; } elseif(stristr($userbrowser,'text/html')) { $_REQUEST['html'] = 1; } if(!defined('WAP')) define('WAP',isset($_REQUEST['wap']) ?

和index.PHP
<?PHP include "app/config.PHP"; include "app/detect.PHP"; if ($page_name=='') { include $browser_t.'/index.html'; } elseif ($page_name=='index.html') { include $browser_t.'/index.html'; } elseif ($page_name=='singlepage.html') { include $browser_t.'/singlepage.html'; } elseif ($page_name=='categories.html') { include $browser_t.'/categories.html'; } elseif ($page_name=='contact.html') { include $browser_t.'/contact.html'; } else { include $browser_t.'/404.html'; } ?>
<?PHP $current_page_uri = $_SERVER['REQUEST_URI']; $part_url = explode("/",$current_page_uri); $page_name = end($part_url); $email_id = "s.hidayath@agileits.com"; ?>
当加载索引文件时,它应检测设备并将其重定向到正确的根,但在我的情况下它不会
我得到以下错误
( ! ) Notice: Undefined index: ALL_HTTP in C:\Users\sanoj\Documents\NetBeansprojects\video-site-2\app\detect.PHP on line 118 Call Stack # Time Memory Function Location 1 0.0090 233992 {main}( ) ..\index.PHP:0 2 0.0230 295896 include( 'C:\Users\sanoj\Documents\NetBeansprojects\video-site-2\app\detect.PHP' ) ..\index.PHP:11 ( ! ) Warning: include(web/404.html): Failed to open stream: No such file or directory in C:\Users\sanoj\Documents\NetBeansprojects\video-site-2\index.PHP on line 30 Call Stack # Time Memory Function Location 1 0.0090 233992 {main}( ) ..\index.PHP:0 ( ! ) Warning: include(): Failed opening 'web/404.html' for inclusion (include_path='.;C:\PHP\pear') in C:\Users\sanoj\Documents\NetBeansprojects\video-site-2\index.PHP on line 30 Call Stack # Time Memory Function Location 1 0.0090 233992 {main}( ) ..\index.PHP:0
首先,NetBeans IDE会向您显示这些警告,以便您不直接信任$_REQUEST值并以某种方式验证它.通过检查isset($_ REQUEST [‘wap’]),您已经在检查IDE建议的哪个部分.此过程可以有其他步骤,您应该在使用它之前执行此操作,例如插入数据库.我忽略了许多NetBeans警告,因为NetBeans不知道我将如何处理输入/变量.它只是警告我最佳实践,这可能是也可能不是我的最佳实践.并且警告应该仅作为建议,而不是您必须做的事情.
其次,如果使用filter_input(),则不需要另外使用isset().因为,filter_input()已经为你做了.正如文件所说,
Return Values : Value of the requested variable on success,
FALSEif the filter fails,orNULLif the variable_name variable is not set. If the flagFILTER_NULL_ON_FAILUREis used,it returnsFALSEif the variable is not set andNULLif the filter fails.
所以你可以删除isset(),你的代码应该安全地工作.但您可能仍想检查该值是否设置为应用替代值.在这种情况下,只需使用empty()函数,当filter_input()返回的值为NULL / FALSE时,它将返回FALSE.所以只是否定符合条件的条件.像这样 –
if(!defined('WAP'))
{
define('WAP',!empty(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) || !empty(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING))|| !empty(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)));
}
if (WAP)
{
define('WIRELESS_PROTOCOL',FILTER_SANITIZE_STRING)) ? 'wap' : (!empty(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) ? 'wap2' : (!empty(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) ? 'iphone' : (!empty(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) ? 'imode' : (!empty(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) ? 'IEMobile' :(!empty(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) ? 'html' : (!empty(filter_input(INPUT_REQUEST,FILTER_SANITIZE_STRING)) ? 'Android' : '')))))));
}
第二个错误
Notice: Undefined index: ALL_HTTP
我在$_SERVER的PHP文档中找不到任何名为ALL_HTTP的变量.所以请检查链接并找到一个可以满足您目的的变量.我不确定你到底想要用它做什么,所以我无法提出任何建议.
第三个错误
Warning: include(web/404.html): Failed to open stream.
