php method to prevent browser from going back:
Process

2.php Example: Last step of password modification When successful, if you click the browser to go back to 1.php

Many people have asked, "How can I 'disable' the browser's back button? Make the back page invalid", or "How can I prevent users from Click the back button to return to a previously viewed page?" Among the many solutions found, one suggested disabling page caching. But all of them are very one-sided. They can only ban IE. Chrome browsers are powerless. The following is an article that comprehensively disables the cache of all browsers. It prevents customers from returning to the submission page after submitting the form and prevents repeated submission of forms. Preventing users from going back is very useful
Since there is no way to completely disable the back button, the best solution is to use a mix of client-side scripts and server-side scripts.
The easiest way is to add the <meta>
tag in the header
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache,no-store, must-revalidate"> <META HTTP-EQUIV="pragma" CONTENT="no-cache"> <META HTTP-EQUIV="expires" CONTENT="0">
If you use the above method to force the browser to no longer cache the web page, you must pay attention to the following A few points:
"pragma: no-cache" only prevents the browser from caching the page when using a secure connection.
For pages that are not protected by security, "pragma: no-cache" is considered the same as "expires: -1". At this time, the browser still caches the page, but marks the page as expired immediately.
In IE 4 or 5, the "cache-control" meta http-equiv tag will be ignored and has no effect. In actual applications we can add all this code.
However, Since this method cannot be applied to all browsers, it is not recommended. But if it is in an intranet environment and the administrator can control which browser the user uses, I think some people will still use this method.
