1. 使用readfile()函数: “`php $filename = “path/to/file”; header(‘Content-Description: File Transfer’); header(‘Content-Type: application/octet-stream’); header(‘Content-Disposition: attachment; filename=”‘.basename($filename).'”‘); header(‘Expires: 0’); header(‘Cache-Cont...
$binary_data = file_get_contents('path/to/your/binaryfile.bin', false, null, 0, null); 复制代码 如果您仍然想使用 readfile(),可以在输出文件内容之前使用 ob_start() 和ob_clean() 函数来捕获输出缓冲区的内容。然后,您可以对捕获的内容进行处理,例如将其保存到数据库或转换为适当的二进制格式。 o...
php// 读取二进制文件并打印内容$filename='path/to/your/binary-file.bin';$content=file($filename, FILE_BINARY);if($content) {echo$content; }else{echo"Error: Unable to read the file."; }?> 在这个例子中,file()函数的第二个参数设置为FILE_BINARY,这样它就会以二进制格式读取文件。然后,你可...
function get_gif_header($image_file){/* Open the image file in binary mode */if(!$fp = fopen ($image_file, 'rb')) return 0;/* Read 20 bytes from the top of the file */if(!$data = fread ($fp, 20)) return 0;/* Create a format specifier */$header_format ='A6Version/' ...
if the stream is read buffered and it does not represent a plain file, at most one read of up to a number of bytes equal to the chunk size (usually 8192) is made; depending on the previously buffered data, the size of the returned data may be larger than the chunk size. 参数 handl...

gzread—Binary-safe gz-file read 说明 stringgzread(resource$zp,int$length) gzread()reads up tolengthbytes from the given gz-file pointer. Reading stops whenlength(uncompressed) bytes have been read orEOFis reached, whichever comes first.

You probably wouldn't be here if you hadn't run into a scenario where you needed to leverage PHP to read a stream of binary data. The honest truth is PHP really stinks at this stuff, but as long as we're going to be using it we may as well do our best to make it as painless...
