字节转换为浮点数(php)
如何在 php 中将字节转换为浮点数?就像在 Java 中一样
How can I convert from bytes to float in php? Like in Java
int i = (byte3 & 0xff) << 24 | (byte2 & 0xff) << 16 | (byte1 & 0xff) << 8 | byte0 & 0xff;
Float.intBitsToFloat(i);
推荐答案
可能有更直接的方法,但是给你:
There may be a more direct way, but here you go:
<?php
var_dump(unpack('f', pack('i', 1059760811)));
?>
当然,这取决于机器,但我不知道任何运行 PHP 的机器不使用 IEEE 754 浮点数.
This is, of course, machine dependent, but I don't know of any machine running PHP that doesn't use IEEE 754 floats.
