mysqli_fetch_row()函数以枚举数组的形式获取结果行。
一个PHP结果对象（mysqli_result类）表示由SELECT或DESCRIBE或EXPLAIN查询返回的MySQL结果。
mysqli_fetch_row()函数接受结果对象作为参数，以字符串数组的形式检索其当前行的内容。
mysqli_fetch_row($result);
| 序号 | 参数及说明 |
|---|---|
| 1 | result(必需) 这是表示结果对象的标识符。 |
PHP mysqli_fetch_row()函数返回一个数组（字符串），该数组包含数据搜索当前指向的行中的值。
此函数最初是在PHP版本5中引入的，并且可以在所有更高版本中使用。
以下示例演示了mysqli_fetch_row()函数的用法（面向过程风格），从结果集中取得行：
<?php
$con = mysqli_connect("localhost", "root", "password", "mydb");
mysqli_query($con, "CREATE TABLE myplayers(ID INT, First_Name VARCHAR(255), Last_Name VARCHAR(255), Place_Of_Birth VARCHAR(255), Country VARCHAR(255))");
print("创建表.....\n");
mysqli_query($con, "INSERT INTO myplayers values(1, 'Sikhar', 'Dhawan', 'Delhi', 'India')");
mysqli_query($con, "INSERT INTO myplayers values(2, 'Jonathan', 'Trott', 'CapeTown', 'SouthAfrica')");
mysqli_query($con, "INSERT INTO myplayers values(3, 'Kumara', 'Sangakkara', 'Matale', 'Srilanka')");
print("插入记录.....\n");
//检索表的内容
$res = mysqli_query($con, "SELECT * FROM myplayers");
while ($row = mysqli_fetch_row($res)) {
print("ID: ".$row[0]."\n");
print("First_Name: ".$row[1]."\n");
print("Last_Name: ".$row[2]."\n");
print("Place_Of_Birth: ".$row[3]."\n");
print("Country: ".$row[4]."\n");
}
//结束语句
mysqli_free_result($res);
//关闭连接
mysqli_close($con);
?>输出结果
创建表..... 插入记录..... ID: 1 First_Name: Sikhar Last_Name: Dhawan Place_Of_Birth: Delhi Country: India ID: 2 First_Name: Jonathan Last_Name: Trott Place_Of_Birth: CapeTown Country: SouthAfrica ID: 3 First_Name: Kumara Last_Name: Sangakkara Place_Of_Birth: Matale Country: Srilanka
在面向对象风格中，此函数的语法为$result-> fetch_row();。以下是面向对象风格中此函数的示例；
<?php
//建立连接
$con = new mysqli("localhost", "root", "password", "mydb");
$con -> query("CREATE TABLE Test(Name VARCHAR(255), AGE INT)");
$con -> query("insert into Test values('Raju', 25),('Rahman', 30),('Sarmista', 27)");
$con -> query("insert into Test values('Mohan', 28),('Raghav', 35),('Devika', 30)");
print("创建表.....\n");
$stmt = $con -> prepare( "SELECT * FROM Test WHERE Name in(?, ?, ?, ?)");
$stmt -> bind_param("ssss", $name1, $name2, $name3, $name4);
$name1 = 'Raju';
$name2 = 'Rahman';
$name3 = 'Raghav';
$name4 = 'Devika';
//执行语句
$stmt->execute();
//检索结果
$res = $stmt->get_result();
//获取所有行的内容
while ($row = $res->fetch_row()) {
print("Name: ".$row[0]."\n");
print("Age: ".$row[1]."\n");
print("\n");
}
//结束语句
$stmt->close();
//关闭连接
$con->close();
?>输出结果
创建表..... Name: Raju Age: 25 Name: Rahman Age: 30 Name: Raghav Age: 35 Name: Devika Age: 30
