自PHP 5.1.0 起,data 参数也可以被指定为 stream 资源,这里 stream 中所保存的缓存数据将被写入到指定文件中,这种用法就相似于使用 stream_copy_to_stream() 函数。 参数 filename 要被写入数据的文件名。 data 要写入的数据。类型可以是 string,array 或者是 stream 资源(如上面所
file_put_contents(string$filename,mixed$data,int$flags=0,?resource$context=null):int|false The$filenameand$dataparameters are required while$flagsand$contextare optional. The function returns theintnumber of bytes written to the file. When the write operation fails, it returnsfalseor falsy numbe...
Write to file 说明 public SplFileObject::fwrite ( string $str [, int $length ] ) : int Writes the contents of string to the file 参数 str The string to be written to the file. length If the length argument is given, writing will stop after length bytes have been written or the ...
filename:要被写入数据的文件名。 data:要写入的数据。类型可以是 string,array 或者是 stream 资源(如上面所说的那样)。 如果data 指定为 stream 资源,这里 stream 中所保存的缓存数据将被写入到指定文件中,这种用法就相似于使用 stream_copy_to_stream() 函数。 参数data 可以是数组(但不能为多维数组),这就...
host: string. can be a host, or the path to a unix domain socket. port: int (default is 6379, should be -1 for unix domain socket) connectTimeout: float, value in seconds (default is 0 meaning unlimited) retryInterval: int, value in milliseconds (optional) readTimeout: float, value...

PhpParser\Node\Scalars are nodes representing scalar values, like 'string' (PhpParser\Node\Scalar\String_), 0 (PhpParser\Node\Scalar\LNumber) or magic constants like __FILE__ (PhpParser\Node\Scalar\MagicConst\File). All PhpParser\Node\Scalars extend PhpParser\Node\Expr, as scalars are exp...

比如说ftp服务器,当客户请求一个文件时,服务器只需要检测目标文件是否存在,以及是否有权限读取就可以了,不需要知道这个文件的具体内容,这样的话ftp服务器就不需要把目标文件读入应用程序缓冲区然后调用send函数来发送,而是直接使用“零拷贝”函数sendfile直接将其发送给客户端。另外,用户代码空间的数据赋值也应该尽可能...
