1] PHP is a server-side coding language widely used for web development.

2] PHP code is often embedded in HTML

3] PHP files usually have save the ".php" extension.

4] PHP file contains the HTML tags some PHP code.

5] PHP script that uses the built-in PHP function "echo" to display text

PHP's syntax is similar to the C language. PHP is a server-side coding language. PHP code is stored as a text file with the ".php" extension. A ".php" file is essentially a web page with HTML text interspersed between one or more blocks of PHP code.

However, it must be opened in a browser with HTTP protocol URLs. In other words, if you double-click on the PHP file icon, it will open locally using the file protocol. For example, if you open the "index.php" file in the root folder of the Apache server, only the text of the PHP code will be displayed. However, if you start the Apache server and

open the URL http://localhost/index.php, the Apache home page will be displayed. Therefore, a PHP parser needs to distinguish between PHP code and other content. When the ".php" file is opened on the website, the HTML engine performs the HTML/CSS/JavaScript part and runs on HTML blocks when it encounters the words contained in the PHP tags. The PHP parser process blocks the response and passes it back to the browser.

PHP ARRAY TYPES

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.
