确定一个字符串是否是serialize()函数的结果/输出的最佳方法是什么? I'd say, try to unserialize it ;-) Quoting the manual : In case the passed string is not unserializeable, FALSE is returned and E_NOTICE is issued. So, you have to check if the return value is false or not (with === or !== , to be sure not to have any problem with 0 or null or anything that equals to false , I'd say)
确定一个字符串是否是serialize()函数的结果/输出的最佳方法是什么? 我会说,试着去反unserialize它;-) 引用手册: 如果传递的字符串不是反序列化的,则返回FALSE并发出E_NOTICE。 所以,你必须检查返回值是否为false (使用===或!== ,确保没有任何问题, 0或null或任何等于false东西,我会说)。 请注意通知:您可能需要/需要使用@运算符。 例如 : $str = 'hjkl'; $data = @unserialize($str); if ($data !== fa

这个问题在这里已经有了答案: 如何将变量和数据从PHP传递到JavaScript? 16个答案 扩展别人的答案: <script> var myvar = <?php echo json_encode($myVarValue); ?>; </script> 使用json_encode()需要: PHP 5.2.0或更高版本 $myVarValue编码为UTF-8(或US-ASCII,当然) 由于UTF-8支持完整的Unicode,因此应该可以安全地进行即时转换。 请注意,由于json_encode转义正斜杠,因此即使是
I'm using phantomJS for the purposes of programmatically taking screenshots of a webpage. My webserver runs on Linux 64 bit. The Scenario My test.php file exec('./phantomjs --version', $o, $e); print_r($o); echo $e; I open test.php in a browser. The out put I get is: 1.9.1 // version number 0 // exit code This proves that I can run commands through exec() and phantomJS is working pe
我正在使用phantomJS来编程捕捉网页的屏幕截图。 我的网络服务器在Linux 64位上运行。 情景 我的test.php文件 exec('./phantomjs --version', $o, $e); print_r($o); echo $e; 我在浏览器中打开test.php 。 我得到的结果是: 1.9.1 // version number 0 // exit code 这证明我可以通过exec()运行命令,而phantomJS正在完美运行。 问题 现在,当我用以下代码替换上述代码时: exec('./phantomjs http://mywebsite.c
This question already has an answer here: How do I check if a string contains a specific word? 37 answers Use the strpos function: http://php.net/manual/en/function.strpos.php $haystack = "foo bar baz"; $needle = "bar"; if( strpos( $haystack, $needle ) !== false ) { echo ""bar" exists in the haystack variable"; } In your case: if( strpos( $a, 'some text' ) !== false ) echo 'text';

Has anybody used a good obfuscator for PHP? I've tried some but they don't work for very big projects. They can't handle variables that are included in one file and used in another, for instance. Or do you have any other tricks for stopping the spread of your code? You can try PHP protect which is a free PHP obfuscator to obfuscate your PHP code. It is very nice, easy to use a
有没有人使用PHP的好混淆器? 我尝试了一些,但他们不适用于非常大的项目。 例如,它们无法处理包含在一个文件中并在另一个文件中使用的变量。 或者你有任何其他技巧来阻止你的代码传播吗? 你可以尝试PHP保护这是一个免费的PHP混淆器来混淆你的PHP代码。 这是非常好的,易于使用,也是免费的。 至于其他人在这里写的关于不使用混淆的原因,因为它可以被破坏等: 我只有一件事可以回答 - 不要锁住你的房门,因为任何
Somehow $_SERVER['REMOTE_ADDR'] returns an empty string, i have the same code (as part of a script) running on multiple servers and it works everywhere else, they are all the same setup. The weird thing is, when I restart apache and load the page, it works exactly once, if I reload the site + all the times after that, it's empty. I've had other people try, same result, empty.
不知何故, $_SERVER['REMOTE_ADDR']返回一个空字符串,我有相同的代码(作为脚本的一部分)在多台服务器上运行,并且它可以在其他地方工作,它们都是相同的设置。 奇怪的是,当我重新启动apache并加载页面时,它只能运行一次,如果我在此之后重新加载站点+,它就是空的。 我有其他人尝试,结果相同,为空。 有人建议这是IPv6配置,我现在已经完全禁用IPv6,但问题仍然存在。 如果您位于代理服务器后面,则可以使

I come from a Java/Grails background and cannot seem to find a definite answer online as to where the service logic for a CakePHP application should be stored. By "Services", I am talking about classes that are usually instantiated through dependency injection to conduct business logic on domain objects. They should be able to query any domain object and make changes in response to a
我来自Java / Grails背景,似乎无法在网上找到明确的答案,应该在哪里存储CakePHP应用程序的服务逻辑。 通过“服务”,我正在讨论通常通过依赖注入实例化的类,以在域对象上执行业务逻辑。 他们应该能够查询任何域对象,并根据控制器操作进行更改。 目前,CakePHP的“组件”类似乎与此行为最接近。 我可以将组件加载到任何控制器中并根据需要执行其方法。 但是,我已经在几个地方看到组件不应该访问数据库,并且这样做会导致一
I'm currently developing a new website where a lot of files will be uploaded and downloaded. When a file is uploaded to the server clamav will start a virus scan on the tmp file before it will be moved to the http server. Everything works great except when i use clamscan and it seems like clamav needs to upload the hole virus database before the scan starts every time and this stress my cp
我目前正在开发一个新网站,上传和下载大量文件。 当文件上传到服务器时,clamav将在tmp文件移动到http服务器之前启动病毒扫描。 除了当我使用clamscan,似乎clamav需要在每次扫描开始之前上传漏洞病毒数据库,并且这会将我的cpu压缩到50%可能需要10 - 20秒时,一切都会很好。 这似乎是一个大问题,因为如果两个用户同时上传文件到我的网站,它可能会很慢。 所以我安装了clamav deamon,因为它在后台运行,并且已经加
