Note: In this small program, one shortcoming is that you can only search for two keywords at the same time, and they are separated by a space " ". If you just search A keyword, such as: "big"
will appear garbled when displayed... ^|_|^, this is the result of the following code:

1 //用空格符把关键字分割开
2 $key=explode(' ', $_GET[keyWord]);

If you want to improve it, you need to do it later here Judged.

The above introduces PHP development_multiple keywords, highlighted, including aspects of content. I hope it will be helpful to friends who are interested in PHP tutorials.
