Warning: feof(): supplied argument is not a valid stream resource in /home/---/public_html/---/---.php on line 191 

Warning: fgets(): supplied argument is not a valid stream resource in /home/---/public_html/---/---.php on line 193 

如何顯示警告信而不是錯誤頁？

Answer 1

檢查返回值fopen。如果閱讀你會得到$處理等於假期間出現了錯誤，但你需要「流資源」傳遞給eof

if($handle === false) { 
    print 'Err found'; 
} 
else { 
    while(!eof($handle)) ... 
}
