從PHP導出有趣的錯誤

此代碼中的錯誤，用於將其導出到excel。如果不使用第1行和第2行代碼正常工作。如果使用第1行和第2行代碼正在工作，但don't export to excel，則重定向到PHP控制頁面。在那裏也可以看到正常的結果。哪裏有問題？從PHP導出有趣的錯誤

$servis_listesi = mysql_query("SELECT * from servis_listesi");

有趣的標題，鏜孔問題： -/ –

在'teknisyen_listesi'表中有'servis_il'，'servis_ilce'字段嗎？ – mith

$ servis_listesi = mysql_query（「SELECT * from servis_listesi」）; 我分享了錯誤的一行。這是真的。是包括servis_il和servis_ilce字段servis_listesi。 –
