php - PHP函数变量传递

Question

生锈，只是试图通过参数传递东西。我究竟做错了什么？

//Insert into DB
function insert(x,y,z)
mysql_query("INSERT INTO x (y)
VALUES ('z')");


insert("test","name","Tyler");

Answer 1

function insert($x,$y,$z){
    mysql_query("INSERT INTO ".$x." (".$y.") VALUES ('".$z."')");
}
insert("test","name","Tyler");

Answer 2

确保您通过以下方式正确引用变量$：

//Insert into DB
function insert($x, $y, $z)
{
    mysql_query("INSERT INTO $x ($y) VALUES ('$z')");
}


insert("test","name","Tyler");
