標題[請益] 怪異的segmentation fault
時間Fri May 13 21:47:41 2011
$semester = intval("99"); // 取得學年
$term = intval("2"); // 取得學期
for($i=0;$i<70000;$i++){
$studentArray[] = array('years' => $semester,
'term' => $term
);
}
上面這段程式碼 於command執行會出現segmentation fault或者是一大堆的錯誤碼
$semester改成"{$semester}" $term改成"{$term}"
或者是for迴圈改成60000次就不會出現錯誤
最奇怪的是出現錯誤 程式竟然還是繼續執行完了...
有人能告訴我為什麼會這樣嗎?
錯誤碼如下
