mysqli_fetch_array()函數(shù)從結(jié)果集中取得一行作為關(guān)聯(lián)數(shù)組，或數(shù)字數(shù)組，或二者兼有。
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。
mysqli_fetch_array($result, [$type]);
| 序號 | 參數(shù)及說明 |
|---|---|
| 1 | result(必需) 這是表示結(jié)果對象的標(biāo)識符。 |
| 2 | 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-
|
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。
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。
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)字數(shù)組或關(guān)聯(lián)數(shù)組，并打印輸出字段值：
<?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("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($con);
?>輸出結(jié)果
創(chuàng)建表..... 插入記錄..... ID: 1 First_Name: Sikhar Last_Name: Dhawan Place_Of_Birth: Delhi Country: India ID: 2 First_Name: Jonathan Last_Name: Trott Place_Of_Birth: CapeTown Country: SouthAfrica ID: 3 First_Name: Kumara Last_Name: Sangakkara Place_Of_Birth: Matale Country: Srilanka
在面向?qū)ο箫L(fēng)格中，此函數(shù)的語法為$result->fetch_array();。以下是面向?qū)ο箫L(fēng)格中此函數(shù)的示例；
<?php
//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
您還可以將結(jié)果行的內(nèi)容檢索為數(shù)字數(shù)組：
<?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("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
