Constants

int zend_get_constant(char *name, uint name_len, zval *result TSRMLS_DC);

Looks up the value of a registered constant. If found, the value will be copied into result and the function will return 0 indicating success.

Argument	Purpose
name	NULL-terminated name of constant to fetch. May also be in the form CLASSNAME::CONSTANT to fetch class constants.
name_len	Length of constant name not including the terminating NULL byte.
result	Preallocated zval container to populate a copy of the constant into.

void zend_register_long_constant(char *name, uint name_len, long value,
 int flags, int module_number TSRMLS_DC);
void zend_register_double_constant(char *name, uint name_len, double value,
 int flags, int module_number TSRMLS_DC);
void zend_register_string_constant(char *name, uint name_len, char *value,
 int flags, int module_number TSRMLS_DC);
void zend_register_stringl_constant(char *name, uint name_len,
 char *value, uint value_len,
 int flags, int module_number TSRMLS_DC);
int zend_register_constant(zend_constant *c TSRMLS_DC);

Registers a constant of the specified type with the value passed. Constants of certain other types (not including Arrays and Objects) can also be registered by manually constructing a zend_constant and passing it to zend_register_constant().

Argument	Purpose
name	NULL-terminated name of constant to register.
name_len	Length of constant name including the trailing NULL byte.
value	Value to initialize the constant with.
value_len	Specific to strings, length of the string value not including the trailing NULL byte.
flags	Any combination of CONST_CS and/or CONST_PERSISTENT.
module_number	Passed unmodified from MINIT or RINIT.
c	Initialized zend_constant structure. Refer to Chapter 12, "Startup, Shutdown, and a Few Points in Between" for more information.
