Php 数组推送替换或擦除现有值
我这里的代码有问题。。。基本上，我有一个页面（edit_patient.php），它从另一个页面（new_patient.php）接收（获取）一个数字。。。在edit_patient.php页面上，我想编辑或添加新信息到已经从new_patient.php发布的内容中。。。 问题是，我有一个数组，我想推动旧数组向现有数组添加新值。。。 当我发布时，信息要么被替换，要么被删除。。。 这是我的密码：Php 数组推送替换或擦除现有值,php,mysql,sql,arrays,array-push,Php,Mysql,Sql,Arrays,Array Push,我这里的代码有问题。。。基本上，我有一个页面（edit_patient.php），它从另一个页面（new_patient.php）接收（获取）一个数字。。。在edit_patient.php页面上，我想编辑或添加新信息到已经从new_patient.php发布的内容中。。。 问题是，我有一个数组，我想推动旧数组向现有数组添加新值。。。 当我发布时，信息要么被替换，要么被删除。。。 这是我的密码： <?php // Update the database with new informati

您将使用此值替换数组值，而不是添加到其中。首先将您的值从MySQL构建到一个数组中，然后将整个数组推送到$\u POST值中。嗯，我应该从sql中分解，然后使用array\u push（$medicing，inclode…）？您不必分解任何内容。您已经从数据库中获取了一个数组。构建一个数组，将$\u POST['mediates']值添加到该数组中，然后用新数组覆盖$\u POST['mediates']。好的，我想我明白了。。。我会试试的B我会让你知道的！！！多谢各位VikingBlooded@VikingBlooded我在代码中添加了一些更改，但仍然出现一些错误。。。
