PHP函数变量传递

问题描述：

Rusty, just simply trying to pass stuff through parameters. What am I doing wrong?

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


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

生锈，只是简单地尝试通过参数传递内容。我究竟做错了什么？ p>

  //插入DB 
function insert（x，y，z）
mysql_query（“INSERT INTO x（y）
VALUES（'z'）”）; \  n 
 
insert（“test”，“name”，“Tyler”）; 
  code>  pre> 
  div>

答

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

答

Be sure you are referencing the variable correctly via $:

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


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