1.列表项

if (strpos($page_name_ulter, 'dissertation' ||  $page_name_ulter, 'vendor' || $page_name_ulter, 'js' || $page_name_ulter, 'css' || $page_name_ulter, 'bootstrap' || $page_name_ulter, 'CI3Xmuqx6MsCFcJf2wod6s0P9Q' ||   $page_name_ulter, 'vendor' || $page_name_ulter, 'vendor' || $page_name_ulter, '=' ||   $page_name_ulter, 'essay?' ||   $page_name_ulter, 'input' ||   $page_name_ulter, 'main.js' || $page_name_ulter, 'main' || $page_name_ulter, 'php/js' || $page_name_ulter, '/' || $page_name_ulter, '.js' || $page_name_ulter, 'rating' || $page_name_ulter, 'intlTelInput' || $page_name_ulter, '.min' || $page_name_ulter, 'images') !== false) { return false; }

Answer 1

你已经这样做了

if (strpos($page_name_ulter, 'dissertation') !== false ||  strpos($page_name_ulter, 'vendor')!== false  and so on

Answer 2

您需要知道 strpos（）功能的基本信号。

strpos（字符串，发现，启动）

但在你的情况下，你只传递 strpos（）函数中的条件。多数民众赞成错误..

检查此

if (strpos($page_name_ulter, 'dissertation') !== false ||  strpos($page_name_ulter, 'vendor') !== false || strpos($page_name_ulter, 'js') !== false || strpos($page_name_ulter, 'css') !== false || strpos($page_name_ulter, 'bootstrap') !== false || strpos($page_name_ulter, 'CI3Xmuqx6MsCFcJf2wod6s0P9Q') !== false ||strpos($page_name_ulter, 'vendor') !== false || strpos($page_name_ulter, 'vendor') !== false || strpos($page_name_ulter, '=') !== false || strpos($page_name_ulter, 'essay?') !== false || strpos($page_name_ulter, 'input') !== false || strpos($page_name_ulter, 'main.js') !== false || strpos($page_name_ulter, 'main') !== false || strpos($page_name_ulter, 'php/js') !== false || strpos($page_name_ulter, '/') !== false || strpos($page_name_ulter, '.js') !== false || strpos($page_name_ulter, 'rating') !== false || strpos($page_name_ulter, 'intlTelInput') !== false || strpos($page_name_ulter, '.min') !== false || strpos($page_name_ulter, 'images') !== false) { return false; }

Answer 3

PHP strpos不适用于单个strpos函数中的多个（OR / ||）条件。

根据文档：strpos查找字符串中第一次出现子字符串的位置

要使其有效，您需要多个strpos IF声明

if (
strpos($page_name_ulter,'dissertation') !== false || 
strpos($page_name_ulter,'vendor') !== false
) {

echo 'Founded';
}

Answer 4

由于strpos()不适用于多个&& OR ||条件，因此您需要添加)，strpos和!== false，如下所示：

if (strpos($page_name_ulter, 'dissertation') !== false ||  strpos($page_name_ulter, 'vendor') !== false || strpos($page_name_ulter, 'js') !== false || strpos($page_name_ulter, 'css') !== false || strpos($page_name_ulter, 'bootstrap') !== false || strpos($page_name_ulter, 'CI3Xmuqx6MsCFcJf2wod6s0P9Q') !== false ||strpos($page_name_ulter, 'vendor') !== false || strpos($page_name_ulter, 'vendor') !== false || strpos($page_name_ulter, '=') !== false || strpos($page_name_ulter, 'essay?') !== false || strpos($page_name_ulter, 'input') !== false || strpos($page_name_ulter, 'main.js') !== false || strpos($page_name_ulter, 'main') !== false || strpos($page_name_ulter, 'php/js') !== false || strpos($page_name_ulter, '/') !== false || strpos($page_name_ulter, '.js') !== false || strpos($page_name_ulter, 'rating') !== false || strpos($page_name_ulter, 'intlTelInput') !== false || strpos($page_name_ulter, '.min') !== false || strpos($page_name_ulter, 'images') !== false) { return false; }

注意： - 更好的解决方案是使用preg_match()

Answer 5

正如其他人提到的那样，您应该知道<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div ng-app = "app"> <div ng-controller="Main"> <div > <table class="table table-bordered"> <tr ng-repeat="d in data | filter: {completed: false }"> <td>{{d.content}}</td> </tr> </table> </div> </div> </div>期望的内容，请看一下：strpos 以下建议是减少对strpos的许多函数调用

因为你有很多不同的价值观，我建议其他方法。如果你的字符串只包含你要搜索的值，我会去一个数组，条件可以使用strpos if (in_array($ultravariable, $arrayWithPossibleValues)) { }应该是您正在搜索的包含wach值的数组。

如果您正在搜索的字符串（超变量）确实包含更多数据，但您只需要检查它是否以不同的值开头，那么我会选择$arrayWithPossibleValues。

preg_match 在这里，您可以使用value1，value2等替换可能的值，并记住将它们与if ( preg_match("/^(value1|value2|value3)/", $ultravariable)) { }分开。

希望这有帮助
