MySQL Fetch Array Function in PHP

Introduction

 

In this article I explain the "MySQL_Fetch_Array()" function in PHP. This function fetches the data from your table. The MySQL_fetch_array() function fetches the result row as an associative array, a numeric array, or both and gets a row from the MySQL_query() function and returns an array on success.

 

Syntax

 

MySQL_fetch_array(data,Array_type);

Parameter
data	Required. Specifies which data pointer to use. The data pointer is the result from a MySQL_Query() function.
Array_type	The type of the array to be fetched. It is a constant and can use the following values MYSQL_ASSOC, MYSQL_NUM, and MYSQL_BOTH.

 

Returns an array corresponding to the fetched row and this function returns field names that are case-sensitive.

 

MySQL_Fetch_Array with MySQL_NUM

<?php
MySQL_connect("localhost", "root", "") or
die("Could not connect: " . MySQL_error());
MySQL_select_db("smart");
$rs = MySQL_query("SELECT c_id, c_name FROM courses");
while ($row = MySQL_fetch_array($rs, MYSQL_NUM))
{
echo "<pre>";
printf("ID: %s Name: %s", $row[0], $row[1]);
}
MySQL_free_result($rs);
?>

Output

 

 

 

MySQL_Fetch_Array with MySQL_ASSOC

<?php
MySQL_connect("localhost", "root", "") or
die("Could not connect: " . MySQL_error());
MySQL_select_db("smart");
$rs = MySQL_query("SELECT c_id, c_name FROM courses");
while ($row = MySQL_fetch_array($rs, MYSQL_ASSOC))
{
echo "<pre>";
printf("ID: %s Name: %s", $row['c_id'], $row['c_name']);
}
MySQL_free_result($rs);
?>

Output

 

 

MySQL_Fetch_Array with MySQL_BOTH

<?php
MySQL_connect("localhost", "root", "") or
die("Could not connect: " . MySQL_error());
MySQL_select_db("smart");
$rs = MySQL_query("SELECT c_id, c_name FROM courses");
while ($row = MySQL_fetch_array($rs, MYSQL_BOTH))
{
echo "<pre>";
printf("ID: %s Name: %s", $row[0], $row['c_name']);
}
MySQL_free_result($rs);
?>
