// the following array description (line 64 of the code) is, to my eye, complete and accurate:
$choicetext = array("", "C/C++", "Java", "Perl", "PHP", "VB/VBA/VBScript", "Andere");
// but it returns this error message:
Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ',' or ';' in /Library/WebServer/Documents/results.php on line 64語法錯誤（顯然具有良好的語法）
在我看來好像逗號和結束「;」是在正確的地方。我已經在'Net for T_CONSTANT_ENCAPSED_STRING'搜索過，但在我發現的討論中發現的異常與此不一樣。如果任何人都可以直接告訴我，我將不勝感激。
下面是使用PHP和MySQL整個網頁，練習：「刪除\」

謝謝！全部......你們搖滾。我打算清理其餘的代碼並嘗試一下。 – zen 2011-02-23 01:10:42
