PHP strpos not working

由 ≡放荡痞女 提交于 2019-12-11 01:44:35
问题 I've always had problems with strpos, I understand the num v. boolean issue, but I can NOT get this working. The $cur_key value is something like "page=>name"... $pos = strpos($cur_key, "=>"); if ($pos !== false) { $mod = explode("=>",$cur_key); $path = $mod[0]; $param = $mod[1]; }else{ $path = $cur_key; } If it's in there it should split it into the two values but no matter what I try it's always just returning the original value... 回答1: $mod = explode('=>',$cur_key); $path=$mod[0]; if

问题 How to find positions of a character in a string or sentence in php $char = 'i'; $string = 'elvis williams'; $result = '3rd ,7th and 10th'. I tried strpos..but no use.. 回答1: This will give you the position of $char in $string: $pos = strpos($string, $char); If you want the position of all occurences of $char in string: $positions = array(); $pos = -1; while (($pos = strpos($string, $char, $pos+1)) !== false) { $positions[] = $pos; } $result = implode(', ', $positions); print_r($result); Test

问题 I'm trying to search a PHP file for a string and when that string is found I want to return the whole LINE that the string is on. Here is my example code.

PHP: How to Properly Use Strpos() to Find a Word in a String

由 浪尽此生 提交于 2019-12-08 13:58:00
问题 If one is experienced in PHP, then one knows how to find whole words in a string and their position using a regex and preg_match() or preg_match_all. But, if you're looking instead for a lighter solution, you may be tempted to try with strpos(). The question emerges as to how one can use this function without it detecting substrings contained in other words. For example, how to detect "any" but not those characters occurring in "company"? Consider a string like the following: "Will *any*

Check if string contains one of several words

问题 I am trying to make a word filter in php, and I have come across a previous Stackoverlow post that mentions the following to check to see if a string contains certain words. What I want to do is adapt this so that it checks for various different words in one go, without having to repeat the code over and over. $a = 'How are you ?'; if (strpos($a,'are') !== false) { echo 'true'; } Will it work if I mod the code to the following ?...... $a = 'How are you ?'; if (strpos($a,'are' OR $a,'you' OR

0x01 例题 这儿举例安恒的一道月题 tips:利用ssrf，gopher打内网 0x02 贴出代码 <?php highlight_file ( __FILE__ ) ; $x = $_GET [ 'x' ] ; $pos = strpos ( $x , "php" ) ; if ( $pos ) { exit ( "denied" ) ; } $ch = curl_init ( ) ; curl_setopt ( $ch , CURLOPT_URL , " $x " ) ; curl_setopt ( $ch , CURLOPT_RETURNTRANSFER , true ) ; $result = curl_exec ( $ch ) ; echo $result ; 0x03分析过程 首先 x 我们可以控制， x可利用的协议有 gopher 、 dict 、 http 、 https 、 file 等 file 协议可以用于查看文件 dict 协议可以用于刺探端口 gopher 协议支持 GET&POST 请求，常用于攻击内网 ftp 、 redis 、 telnet 、 smtp 等服务，还可以利用 gopher 协议访问 redis 反弹 shell 首先我们利用file读取文件 先上脚本扫描一下目录，得到 flag.php 。 一般我们还可以读取 /etc/hosts

php端检测是否移动设备的完整代码

做网页时，需要得到当前打开网页页面的设备是PC的浏览器，还是移动设备的浏览器，再针对不同设备，让页面显示合适内容； 针对这个需求场景，个人认为有三种方法可以实现： 方法一： 通过css ； 方法二，通过js； 方法三 通过 php端； 这三种方法按业务需求，进行采用，会有不一样的效果； css 通过 @media 属性 ，设置不一样屏幕尺寸 显示不一样的页面；达到页面匹配不同尺寸的效果； 通过js 判断设备是移动设备，pc设备、微信客户端等，再做对应的跳转到合适的业务页面展示给客户端； 方式三，通过php端判断 访问的设备是 pc还是移动设备； 后端返回 不一样的业务内容； 个人觉得方式三 适合复杂的，业务需求。 下面就 提供一个 php端 判断设备的代码吧。 /** * 是否移动端访问访问 */ public function _is_mobile() { if (isset ($_SERVER['HTTP_X_WAP_PROFILE'])) { // 如果有HTTP_X_WAP_PROFILE则一定是移动设备 return true; } elseif (isset ($_SERVER['HTTP_USER_AGENT'])) { // 判断手机发送的客户端标志,兼容性有待提高 $clientkeywords = [ 'nokia', 'sony', 'ericsson',
