php bom去除工具,php批量去除bom的代码
php批量去除文件bom代码的功能,支持文件夹批量去除。具体php文件代码如下:
<span style="font-size: 14px;"><?php</span><br />header('content-Type: text/html; charset=utf-8');<br />$auto=1;/*设置为1标示检测BOM并去除,设置为0标示只进行BOM检测,不去除*/<br />$basedir='.';<br />$loop=true;//www.phpernote.com<br />echo '当前查找的目录为:'.$basedir.'当前的设置是:';<br />echo '(1)',$loop?'检查当前目录以及当前目录的子目录':'只针对当前目录进行检测';<br />echo '(2)',$auto?'检测文件BOM同时去除检测到BOM文件的BOM<br />':'只检测文件BOM不执行去除BOM操作<br />';<br /><br />checkdir($basedir,$loop);<br />function checkdir($basedir='',$loop=true){<br /> $basedir=empty($basedir)?'.':$basedir;<br /> if($dh=opendir($basedir)){<br /> while (($file=readdir($dh))!==false){<br /> if($file!='.'&&$file!='..'){<br /> if(!is_dir($basedir.'/'.$file)){<br /> echo '文件: '.$basedir.'/'.$file .checkBOM($basedir.'/'.$file).' <br>';<br /> }else{<br /> if(!$loop) continue;<br /> $dirname=$basedir.'/'.$file;<br /> checkdir($dirname);<br /> }<br /> }<br /> }<br /> closedir($dh);<br /> }<br />}<br />function checkBOM($filename){<br /> global $auto;<br /> $contents=file_get_contents($filename);<br /> $charset[1]=substr($contents,0,1);<br /> $charset[2]=substr($contents,1,1);<br /> $charset[3]=substr($contents,2,1);<br /> if(ord($charset[1])==239&&ord($charset[2])==187&&ord($charset[3])==191){<br /> if($auto==1){<br /> $rest=substr($contents,3);<br /> rewrite($filename,$rest);<br /> return (' <font color=red>找到BOM并已自动去除</font>');<br /> }else{<br /> return (' <font color=red>找到BOM</font>');<br /> }<br /> }else{<br /> return (' 没有找到BOM');<br /> }<br />}<br />function rewrite($filename,$data){<br /> $filenum=fopen($filename,'w');<br /> flock($filenum,LOCK_EX);<br /> fwrite($filenum,$data);<br /> fclose($filenum);<br /><p>}<span style="font-size: 14px;">
将以上代码保存为后缀为php的文件放到需要去除bom的文件目录里面,然后运行该php文件,将会对该目录以及该目录所有的子目录下的文件进行bom检查并去除bom,运行结果页面如下:

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
