In the process of development, you will often encounter a need to provide an input box for others, and then others enter some ID or keyword, such as the wordpress background tag input box:

This is just a comma in English. What if someone accidentally enters a comma in Chinese? What about decimal point?

So I wrote an expression with a regular expression and replaced the line break with a space with a comma.

Replace the submitted id with a space newline character with a comma, and then use the explode function to switch to an array.

The Code is as follows:

$ Ids = $ _ POST ["ID"];
$ Id = preg_replace ("/(\ n) | (\ s) | (\ t) | (\ ') | (,)/",', ', $ ids );
$ Topicids = explode (",", $ tids );

This adds a decimal point filter.

The Code is as follows:

$ Ids = preg_replace ("/(\ n) | (\ s) | (\ t) | (\ ') | (,) | (\.) /", ',', $ ids );

OK. After such processing, there will be no problem.

Tip: in fact, it is a better choice for xiaobian to handle this problem before submitting JavaScript code.
