php array types

 

PHP ARRAY TYPES

PHP Array Type


PHP ARRAY

  1]Array is a special type of variable that we use to store        or store multiple values in a single variable without creating     multiple variables to store these values.

  2]  We
 use the array function ( ) to create an array in PHP.


PHP ARRAY TYPES :-

1] Indexed  Array 

 1]  PHP index array is an array represented by an index number. 
 2] All elements of an array are represented by index numbers starting from 0. 
 3] PHP index arrays can store numbers, strings, or single objects. 
 4] PHP indexed arrays are also called numeric arrays.

SYNTAX ::- 

   foreach($array as $value)
       {
            statement;
            statement;
            statement;
           }


PHP Array Type

Example :-

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>array</title>
</head>
<body>
    <?php
     $student=array("vitthal","seeta","radha","ram");
     rsort($student);
     foreach($student as $a)
     {
        echo $a."<br>";
     }
    ?>
</body>
</html>

PHP Array Type

Output

vitthal
seeta
ram
radha

2] Associative Array

 1] PHP allows you to associate a name/tag with any string in PHP using the => symbol.
 2] This way you can easily remember because each element is represented by a label instead of an additional number.

SYNTAX ::-

foreach ($array as $key => $value)
      {
            
         statement;
         statement;
      }

 Associative Array 

Example 


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>array</title>
</head>
<body>
    <?php
    $student=array(3=>"vitthal",1=>"seeta",2=>"radha");
    foreach($student as $x=>$y)
    {

    echo $y."your Roll no is ".$x."<br> ";
   }
    ?>
</body>
</html>

 Associative Array

Output ::-

vitthalyour Roll no is 3
seetayour Roll no is 1
radhayour Roll no is 2

 3] Multidimension Array

1] PHP multidimensional arrays are also called arrays. 
2] It allows you to store table data in an array.
3] In PHP, multidimensional arrays can be represented as a row*column matrix.

 Multidimension Array ::-

Example


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>array</title>
</head>
<body>
<?php
$COMPANY = array (
  array("TCS",22,18),
  array("IBM",15,13),
  array("INFOSYS",5,2),
  );
 
echo $COMPANY[0][0].": In stock: ".$COMPANY[0][1].", sold: ".$COMPANY[0][2].".<br>";
echo $COMPANY[1][0].": In stock: ".$COMPANY[1][1].", sold: ".$COMPANY[1][2].".<br>";
echo $COMPANY[2][0].": In stock: ".$COMPANY[2][1].", sold: ".$COMPANY[2][2].".<br>";

?>

</body>
</html>

      Multidimension Array::-

Output :-

TCS: In stock: 22, sold: 18.
IBM: In stock: 15, sold: 13.
INFOSYS: In stock: 5, sold: 2.
