在Linux上的PHP 5.6中未定义bintohex()和random_bytes()函数 [英] bintohex() and random_bytes() functions are undefined in PHP 5.6 on Linux

问题描述

我正要打电话

echo bintohex(random_bytes(30));

但是我的日志显示

PHP Fatal error:  Call to undefined function bintohex()

PHP 5.6.17
Apache 2.2.15
CentOS 6.7
Mcrypt 2.5.8 (已在phpinfo()页面上安装并验证)
extension = mcrypt.so (显示)

PHP 5.6.17
Apache 2.2.15
CentOS 6.7
Mcrypt 2.5.8 (installed and verified on phpinfo() page)
extension=mcrypt.so (present)

为什么我找不到bintohex()或random_bytes()函数?

Any ideas why I can't find bintohex() or random_bytes() functions?

推荐答案

因为它 bin2hex http://php.net/manual/en/function.bin2hex.php 不是"bintohex"

Because it bin2hex http://php.net/manual/en/function.bin2hex.php not "bintohex"

random_bytes 基本上仅存在于PHP 7中，但这是5.x版本 https://github.com/paragonie/random_compat

random_bytes basically exist only in Php 7 according to docs http://php.net/random_bytes but here is polyfill to 5.x version https://github.com/paragonie/random_compat
