Answer 1

使用HEREDOCs时，token 需要单独一行，也不要在该$sql =行的 token 后面加分号。

$sql = <<<MySQL_Query

CREATE TABLE IF NOT EXISTS Test
{
    ItemID int(3) unsigned NOT NULL auto_increment,
    Title varchar(128) NOT NULL default '',
    Price decimal(3,2) NOT NULL default '',
    PRIMARY KEY (ItemID)
}
MySQL_Query;

Answer 2

< !-- ... -->是 HTML 注释标签。在 php 中你必须使用//,#或/** */.

编辑：

$sql = "CREATE TABLE IF NOT EXISTS Test
{
ItemID int(3) unsigned NOT NULL auto_increment,
Title varchar(128) NOT NULL default '',
Price decimal(3,2) NOT NULL default '',
PRIMARY KEY (ItemID)
}";

mysql_query($sql);
