This article mainly explains "php PDO's preprocessing statement is what", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's take a small series to take you to learn "what is the preprocessing statement of php PDO"!

1. Position parameters

Use the bindParam() function instead of providing values directly.

$tis = $conn->prepare("INSERT INTO STUDENTS(name, age) values(?, ?) ");$tis->bindValue(1,'mike');$tis->bindValue(2,22);$tis->execute();

2. Named parameters

Named parameters are also preprocessed sentences that map values/variables to named locations in the query. Because there is no positional binding, it works well in queries that use the same variable multiple times.

$name='Rishabh'; $age=20;$tis = $conn->prepare("INSERT INTO STUDENTS(name, age) values(?, ?) ");$tis->bindParam(1,$name);$tis->bindParam(2,$age);$tis->execute();php frames What php frames are there:
