我有兩種PHP格式的輸入字段。這些字段需要保存到數組中,並且輸出應該在括號中包含它旁邊每個單詞的單詞長度。還需要評估哪個輸入字段1或2具有最長的單詞以及每個字段中有多少單詞。它在執行過程中顯示錯誤。語法錯誤,文件 Screenshot 1Screenshot 2將字符串分解爲數組PHP

if (isset($_POST['submit'])) {
$input1 = $_POST['input1'];

//example $input2 = "Counting words and showing(7) like this word<< ";
if (empty($input1)) {
echo "You need to enter both fields !";

你能進一步幫助! –
你真的只需要調試它。通常,當你遇到錯誤時,你要做的第一件事就是啓用錯誤報告。但是出於某種原因,你已經不再使用它了:'error_reporting(0);'。 「它在執行過程中顯示錯誤。」什麼錯誤? *您需要輸入兩個字段!*? – HPierce
我修改了代碼。你能再次測試嗎? –
