編寫HTML與PHP變量到一個外部文件

-1

我怎樣寫一個變量作爲字符串使用fwrite的一個外部文件 - 用單引號「（VAR）」周圍的變量：編寫HTML與PHP變量到一個外部文件

$sql_data_element = "UPDATE artister SET data_two="$data_two" WHERE brugernavn= ' . $brugernavn . '";

寫data_two = 「$ data_two」給出了一個錯誤 - 需要適當逃避工作...

赫斯完整的代碼被寫入到外部文件：

寫入外部文件的HTML必須經過像這樣：

$sql_data_element = "UPDATE artister SET data_one='$data_one' WHERE username='new user' ";

這是怎麼回事：提交用戶名，密碼，MySQL中「的index.php」後從$template_content寫入一個新的文件，並重定向到這一點。基於新文件用戶的書面內容有更多選擇。

更新你以什麼文件的內容是現在的問題，和/或var_dump。 –

我已更新內容 - – jan199674

我不知道你爲什麼要在文件中寫出所有內容。你首先使用的是純html，然後是一個沒有php標籤的db查詢，然後是js。我覺得你需要重新考慮這一點。就像我上面提到的;用你現在得到的輸出更新你的問題。看來你想排除html和js，只將查詢寫入文件，對嗎？ –

$template_content = '$sql_data_element = "UPDATE artister SET data_one="\'$data_one\'" WHERE username= \'' . $username . '\'";';

將輸出

$sql_data_element = "UPDATE artister SET data_one='$data_one' WHERE username='new user' ";

按照您的要求

你確定你不想輸出

$sql_data_element = "UPDATE artister SET data_one='some value' WHERE username='new user' ";？

上拋出錯誤，意外的'''已經嘗試過 - HTML將是單引號和雙引號： data_one =「'$ data_one'」我需要它只有單引號： data_one ='$ data_one' – jan199674

注意你的報價字符，並使用heredoc，以增強可讀性：

<?php 

$username = 'James Bond'; 
$template_content = <<<CODE 
\$sql_data_element = "UPDATE artister SET data_one='\$data_one' WHERE username='$username'"; 
CODE; 

var_dump($template_content);

的上面的輸出顯然是：

string(91) "$sql_data_element = "UPDATE artister SET data_one='$data_one' WHERE username='James Bond'";"

無法使用HEREDOC - $ template_content同時包含PHP，HTML和JQuery在外部文件中使用 – jan199674

@ jan199674我不明白這個聲明 - 一個字符串包含什麼或者在以後的某個時間點如何使用它與它的定義無關，你可以在這樣一個字符串中混合你想要的任何標記或代碼在古典或'heredoc'風格的字符串定義中沒有區別 – arkascha

@arkascha你有沒有看到他們的編輯？我真的不知道是什麼你要在這裏做;請參閱[我的評論]（http://stackoverflow.com/questions/42392330/writing-html-with-php-variable-to-an-external-file?noredirect=1#comment71933428_42392330）。 –
