Class Methods
getenv
static method getenv : string ($name : string);The getenv() function searches the environment list to find the environment variable name, and returns a pointer to the corresponding value string.
See the detail of the getenv function in the case of Linux.
setenv
static method setenv : int ($name : string, $value : string, $overwrite : int);The setenv() function adds the variable name to the environment with the value value, if name does not already exist. If name does exist in the environment, then its value is changed to value if overwrite is nonzero; if overwrite is zero, then the value of name is not changed. This function makes copies of the strings pointed to by name and value (by contrast with putenv(3)).
See the detail of the setenv function in the case of Linux.
unsetenv
static method unsetenv : int ($name : string);The unsetenv() function deletes the variable name from the environment. If name does not exist in the environment, then the function succeeds, and the environment is unchanged.
See the detail of the unsetenv function in the case of Linux.
defined
static method defined : int ($macro_name : string, $value = undef : object of Int|Long|Double);Checks if the macro in C langauge is defined. If the macro is defined, returns 1. Otherwise returns 0.
If $value is specifed and $macro_name is defined, the macro value converted to the given type is set to $value.
