如何记住正则表达式中的所有出现？

Question

There is a line 有一条线

int gg = 665 j h = 78;

Check it on the condition and memorize the characters gg, j, h. 根据情况检查并记住字符gg，j，h。 Wrote regex: 编写正则表达式：

/^\s*int\s+(?:\s*([a-z]+)\s*(?:=\s*[0-9]+\s*){0,1})+;$/

Get: 得到：

Array
(
    [0] => Array
    (
        [0] => int gg =665 j h = 78;
    ),
    [1] => Array
    (
        [0] => h
    )
)

It turned out that only remember the last entry, I want to catch all the others too. 原来，只记得最后一个条目，我也想抓住所有其他条目。
