我从各种来源的大杂烩和几周的我称之为“整体沉浸式学习”的过程中构建了这段代码。换句话说,我不知道关于php的深蹲,只是认为我可以伪造它,但显然我不能。
任何人,我知道我在下面所做的事情会让几个看到它的人对我对你心爱的 php 所做的事情感到极度恐惧,但只有 2 周的自我教育是无济于事的,至少它只是现在抛出三个通知,而不是它过去所做的所有警告、尖叫警告和致命错误。
我得到的最后一个错误是......
( ! ) 注意:未定义变量:第 65 行 E:\wamp\www\complete-x013_php2\iframe1\contact.php 中的 error_name
( ! ) 注意:未定义变量:第 77 行 E:\wamp\www\complete-x013_php2\iframe1\contact.php 中的 error_email
( ! ) 注意:未定义变量:第 89 行 E:\wamp\www\complete-x013_php2\iframe1\contact.php 中的 error_code
