PHP result對象（mysqli_result類）表示MySQL結(jié)果，由SELECT或DESCRIBE或EXPLAIN查詢返回。 mysqli_fetch_array()函數(shù)的作用是：接受一個結(jié)果對象作為參數(shù)，檢索給定結(jié)果對象中當(dāng)前行的內(nèi)容，并將其作為關(guān)聯(lián)數(shù)組或數(shù)值數(shù)組返回。

語法:

mysqli_fetch_array($result, [$type]);

參數(shù)說明: result(必需)這是表示結(jié)果對象的標(biāo)識符。 type(必需)這是一個整數(shù)值，指定返回數(shù)組的類型。該type的值是以下值之一- MYSQLI_ASSOC； MYSQLI_NUM； MYSQLI_BOTH； 返回值 PHP mysqli_fetch_array()函數(shù)返回一個數(shù)組（關(guān)聯(lián)或數(shù)字），該數(shù)組保存結(jié)果對象的當(dāng)前行。如果沒有更多行，此函數(shù)將返回NULL。

PHP版本 此函數(shù)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。

示例1： 以下示例演示了mysqli_fetch_array()函數(shù)的用法（面向過程風(fēng)格）:從結(jié)果集中取得行作為數(shù)字?jǐn)?shù)組或關(guān)聯(lián)數(shù)組，并打印輸出字段值：

$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("創(chuàng)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("插入記錄.....\n");

//檢索表的內(nèi)容

$res = mysqli_query($con, "SELECT * FROM myplayers");

//獲取所有行作為數(shù)組

while($row = mysqli_fetch_array($res, MYSQLI_ASSOC)){

print("ID: ".$row["ID"]."\n");

print("First_Name: ".$row["First_Name"]."\n");

print("Last_Name: ".$row["Last_Name"]."\n");

print("Place_Of_Birth: ".$row["Place_Of_Birth"]."\n");

print("Country: ".$row["Country"]."\n");

}

//結(jié)束語句

mysqli_free_result($res);

//關(guān)閉連接

mysqli_close($con);

?>

輸出結(jié)果

創(chuàng)建表.....

插入記錄.....

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

示例2：在面向?qū)ο箫L(fēng)格中，此函數(shù)的語法為$result->fetch_array();。以下是面向?qū)ο箫L(fēng)格中此函數(shù)的示例；

//建立連接

$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)");

print("創(chuàng)建表.....\n");

$stmt = $con -> prepare( "SELECT * FROM Test WHERE Name in(?, ?)");

$stmt -> bind_param("ss", $name1, $name2);

$name1 = 'Raju';

$name2 = 'Rahman';

//執(zhí)行語句

$stmt->execute();

//檢索結(jié)果

$result = $stmt->get_result();

//獲取所有行作為數(shù)組

while($row = $result->fetch_array(MYSQLI_ASSOC)){

print("Name: ".$row["Name"]."\n");

print("Age: ".$row["Age"]."\n");

}

//結(jié)束語句

$stmt->close();

//關(guān)閉連接

$con->close();

?>

輸出結(jié)果：

創(chuàng)建表.....

Name: Raju

Age: 25

Name: Rahman

Age: 30

示例3：您還可以將結(jié)果行的內(nèi)容檢索為數(shù)字?jǐn)?shù)組：

$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("創(chuàng)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("插入記錄.....\n");

//檢索表的內(nèi)容

$res = mysqli_query($con, "SELECT * FROM myplayers");

//獲取所有行作為數(shù)組

while($row = mysqli_fetch_array($res, MYSQLI_NUM)){

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");

}

//結(jié)束語句

mysqli_free_result($res);

//關(guān)閉連接

mysqli_close($con);

?>

輸出結(jié)果：

創(chuàng)建表.....
