Here are the instructions to create dynamic array using php.<\/p>\n

Dynamic Array is one where the elements can be altered during run time.<\/strong><\/p>\n

This title explain you both single dimensional<\/strong> and multidimensional<\/strong> array.<\/p>\n

First let we declare the variables,<\/p>\n

\/\/Single Dimensional\r\n$single_arr<\/strong>=array();\r\n\/\/Multidimensional\r\n$multi_arr<\/strong>=array();<\/code><\/pre>\n
We can able to create dynamic new array from the database tables or existing arrays.<\/p>\n
Now we create the dynamic array from tables<\/strong><\/p>\n
TableName<\/strong>: test<\/p>\n
\r\n
 sno<\/strong><\/td>dept<\/strong><\/td>name<\/strong><\/td><\/tr>\r\n
1<\/td>P&AR<\/td>D.Premkumar<\/td><\/tr>
2<\/td>H,P&E<\/td>N.Thangamani<\/td><\/tr>
3<\/td>Agriculture<\/td>K.Shanmugam<\/td><\/tr>
4<\/td>RD&PR<\/td>P.Usha<\/td><\/tr>
5<\/td>H&FW<\/td>M.Vijayarani<\/td><\/tr>
6<\/td>Public<\/td>R.Kalaimani<\/td><\/tr>
7<\/td>Public<\/td>E.Dhandapani<\/td><\/tr>
8<\/td>P&AR<\/td>A.Anbarasan<\/td><\/tr>
9<\/td>H&FW<\/td>B.Kamakshi<\/td><\/tr>
10<\/td>Sch.Edn.<\/td>M.Vijayalakshmi<\/td><\/tr>
11<\/td>Agriculture<\/td>M.R.Amamath<\/td><\/tr>
12<\/td>L&E<\/td>K.Lakshmi<\/td><\/tr>
13<\/td>Revenue<\/td>S.Karikalan<\/td><\/tr>
14<\/td>Home<\/td>S.Sellakkannu<\/td><\/tr>
15<\/td>Agriculture<\/td>G.Ramanuja Surendranath<\/td><\/tr><\/table><\/code><\/pre>\n
$sql=\"SELECT sno,dept,name FROM test\";\r\n$query=@mysql_query($sql);\r\n$num_query=@mysql_num_rows($query);\r\nif($num_query>0)\t{\r\nwhile($fetch=mysql_fetch_assoc($query))\t{\r\n\/\/Single Dimension Array\r\n$single_arr[$fetch['sno']]=$fetch['name'];\r\n\/\/Multiple Dimension Array\r\n$multi_arr[$fetch['dept']][$fetch['sno']]=$fetch['name'];\r\n}\r\n}\r\n\/\/echo ' < pre > ';\r\n\/\/print_r( $single_arr );\r\n\/\/print_r( $multi_arr );\r\n<\/code><\/pre>\n
Below are the output for created dynamic single dimensional array<\/p>\n
Array\r\n(\r\n    [1] => D.Premkumar\r\n    [2] => N.Thangamani\r\n    [3] => K.Shanmugam\r\n    [4] => P.Usha\r\n    [5] => M.Vijayarani\r\n    [6] => R.Kalaimani\r\n    [7] => E.Dhandapani\r\n    [8] => A.Anbarasan\r\n    [9] => B.Kamakshi\r\n    [10] => M.Vijay\r\n    [11] => M.R.Amamath\r\n    [12] => K.Lakshmi\r\n    [13] => S.Karikalan\r\n    [14] => S.Sellakkannu\r\n    [15] => G.Ramanuja\r\n)<\/code><\/pre>\n
Below are the output for created dynamic multidimensional array<\/p>\n
