php擴展方法未返回爲什麼？

Question

這是php_ex.cc。當我編譯我的.so庫時，retur（）方法不起作用。爲什麼？我沒有錯誤，但它應該打印「測試」，它不會; t。需要一些help.THX

這裏是個[example.cc]

void Car2::retur() 
{ 
    cout<<"YOU ARE IN CLASS NR 2"<<endl; 
} 

我想提一提的是汽車類和它的方法都在工作。

如果您的retur方法確實在寫入stdout，那麼您應該注意到，PHP的輸出通常與com stdout不一致。

對於CLI SAPI（例如），它可以，但即使如此，通過直接寫入標準輸出，您將繞過PHP的輸出緩衝。

您必須改用php_printf或PHPWRITE。
