putenv
PUTENV(3) 1 PUTENV(3)putenv - Sets the value of an environment variableSYNOPSIS
bool putenv (string $setting)
DESCRIPTION
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-delim-
ited 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 direc-
tive 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(3). These variables will be protected even if safe_mode_allowed_env_vars is set to allow to change them.
PARAMETERS
o $setting
- The setting, like "FOO=BAR"
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Setting an environment variable
<?php
putenv("UNIQID=$uniqid");
?>
NOTES
Warning
The safe_mode_allowed_env_vars and safe_mode_protected_env_vars directives only take effect when safe_mode is enabled.
SEE ALSO getenv(3).
