大家好,我是Phpstudy的开发者猪哥。

Phpstudy是我个人业余时间开发并维,针对phpstudy 后门事件,在这里做一下澄清,这个事件早在2018年12月案件相关网警就已经在公司进行调查,取证,已证明与phpstudy官网无关,软件是被不法分子二次修改。再上传到其他下载站。大家只要官网下载的就不会有问题。

putenv

putenv

(PHP 4, PHP 5)

putenvSets the value of an environment variable

说明

bool putenv ( string $setting )

Adds setting to the server environment. The environment variable will only exist for the duration of the current request. At the end of the request the environment is restored to its original state.

Setting certain environment variables may be a potential security breach. The safe_mode_allowed_env_vars directive contains a comma-delimited list of prefixes. In Safe Mode, the user may only alter environment variables whose names begin with the prefixes supplied by this directive. By default, users will only be able to set environment variables that begin with PHP_ (e.g. PHP_FOO=BAR). Note: if this directive is empty, PHP will let the user modify ANY environment variable!

The safe_mode_protected_env_vars directive contains a comma-delimited list of environment variables, that the end user won't be able to change using putenv(). These variables will be protected even if safe_mode_allowed_env_vars is set to allow to change them.

参数

setting

The setting, like "FOO=BAR"

返回值

成功时返回 TRUE, 或者在失败时返回 FALSE.

范例

Example #1 Setting an environment variable

<?php
putenv
("UNIQID=$uniqid");
?>

注释

Warning

The safe_mode_allowed_env_vars and safe_mode_protected_env_vars directives only take effect when safe_mode is enabled.
