php search function

I’ve been very irritable recently and don’t know how to start learning a piece of code, so I want to write more things for future review.

Recently, after looking at the search function for a few days, I wanted to modify and optimize the search function of phpcms, but I didn’t have any clue. Maybe I slept too late recently, so I rewrote the simple search and organized my ideas.

A simple search only requires constructing a query statement

$sql = "SELECT * FROMsqlWHERE $ziduan LIKE'%$content%'"

After constructing the SQL database query, you can execute the database query

$rs=$db->query($sql);
$rsNum=$rs->num_rows;   //返回查询的行数echo "本次查询到 $rsNum 条记录";

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above has introduced the PHP search function, including related content. I hope it will be helpful to friends who are interested in PHP tutorials.
