Longs (Integers)

Now let's get to the assignment of data to variables, starting with longs. Longs are PHP's integers and are very simple to store. Looking at the zval.value container structure discussed earlier in this chapter, you can see that the long data type is directly contained in the union, namely in the lval field. The corresponding type value for longs is IS_LONG (see Example 33-2).

Example 33-2. Creation of a long.

zval *new_long;

MAKE_STD_ZVAL(new_long);

new_long->type = IS_LONG;
 new_long->value.lval = 10;
Alternatively, you can use the macro ZVAL_LONG:
zval *new_long;

MAKE_STD_ZVAL(new_long);
 ZVAL_LONG(new_long, 10);
