What is an Array?

An arrays is a special variable, which can hold more than one value at a time.

If you have a list of items (a list of indiabix names, for example), storing the indiabixs in single variables could look like this:

$indiabixs1 = "Pakainfo";
$indiabixs2 = "4cgandhi";
$indiabixs3 = "infinityknow";

However we learn to array meaning with php tutorial, what if you want to loop through the indiabixs as well as search a specific one? As well as what if you had not 3 indiabixs, but 300?

The solution is to create an array!

An arrays can hold many values under a single name, as well as you can access the data values by referring to an index no.

array programs in php

Merge Two Array In PHP Into Single One:

$teamplayers1 = array(1,2,3);
$teamplayers2 = array(4,5,6);
$teamplayers3 = array(7,8,9);
$single_merged_array = array_merge($websites_array_listay1,$websites_array_listay2,$websites_array_listay3);
print_r($single_merged_array);

Difference Between Two PHP Arrays:

$teamplayers1 = array(1,2,3,4,-1,-2);
$teamplayers2 = array(-1,-2);
$filtered_array = array_diff($teamplayers1,$teamplayers2);
print_r($filtered_array);

Get Common Elements Among Two PHP Arrays:

$teamplayers1 = array(1,2,3,4,-1,-2);
$teamplayers2 = array(-1,-2,3);
$common_array = array_intersect($teamplayers1,$teamplayers2);
print_r($common_array);

Getting Keys/Values Separately From Associative Array:

$computer_data = array("key1"=>"value 1","key2"=>"value 2","key3"=>"value 3");
 
print_r(array_keys($computer_data));
echo "
";
print_r(array_values($computer_data));

Convert An Array To String And Vice-versa:

$teamplayers1 = array(1,2,3,4,-1,-2);
$converted_string = implode(",",$teamplayers1);
echo $converted_string;
$converted_values = explode(",",$converted_string);
echo print_r($converted_values);

Remove Duplicates From PHP Array:

$unique_array = array_unique($computer_data_with_duplicates);
print_r($unique_array);

How To Print Or Echo All The Values Of An Array In PHP?

Get The Length of an Array – The count() Function

The simple count() method is used to data return the length (the total no of elements) of an array:

php declare empty array

Popular method to initialize empty array in PHP (Simple example of empty array:)

indexed array in php

simple you can use PHP Indexed Arrays

Loop Through an Indexed Array

";
}
?>

associative array in php

echo "Pratksha is " . $age['Pratksha'] . " years old.";
?>

php array foreach

";
}
?>

"35", "bhakti"=>"37", "Naresh"=>"43");

foreach($age as $x => $val) {
  echo "$x = $val
";
}
?>

PHP Array Length Size Count Function With Example

php array of objects

class Car
{
    public $movie;
    public $type;
}

$myCar = new Car();
$myCar->movie = 'tamil';
$myCar->type = 'sedan';

$yourCar = new Car();
$yourCar->movie = 'khatrimaza';
$yourCar->type = 'suv';

$indiabixs = array($myCar, $yourCar);

foreach ($indiabixs as $indiabix) {
    echo 'This indiabix is a ' . $indiabix->movie . ' ' . $indiabix->type . "\n";
}

php print array as string

using PHP implode() Function

";
echo implode("+",$websites_array_list)."
";
echo implode("-",$websites_array_list)."
"; 
echo implode("X",$websites_array_list);
?>

PHP Multidimensional Arrays

";
echo $indiabixs[1][0].": In stock: ".$indiabixs[1][1].", sold: ".$indiabixs[1][2].".
";

";
echo $indiabixs[3][0].": In stock: ".$indiabixs[3][1].", sold: ".$indiabixs[3][2].".
";
?>

PHP – Sort Functions For Arrays

Sort Array in Ascending Order – sort()

Sort Array in Descending Order – rsort()

Example

PHP Array Length Size Count Tutorial With Example

Sort Array (Ascending Order), According to Value – asort()

Example

"35", "bhakti"=>"37", "Naresh"=>"43");
asort($age);
?>

Sort Array (Ascending Order), According to Key – ksort()

"35", "bhakti"=>"37", "Naresh"=>"43");
ksort($age);
?>

Sort Array (Descending Order), According to Value – arsort()

"35", "bhakti"=>"37", "Naresh"=>"43");
arsort($age);
?>

Sort Array (Descending Order), According to Key – krsort()

"35", "bhakti"=>"37", "Naresh"=>"43");
krsort($age);
?>

Numeric Array


   
   
      ";
         }
         
         $membersLevel[0] = "one";
         $membersLevel[1] = "two";
         $membersLevel[2] = "three";
         $membersLevel[3] = "four";
         $membersLevel[4] = "five";
         
         foreach( $membersLevel as $value ) {
            echo "Value is $value 
";
         }
      ?>

Viewing Array Structure and Values

using var_dump

Working With Keys and Values

$keys = ['tamil', 'hindi', 'litanswers'];
$values = ['khatrimaza', 'textsheets', 'litanswers'];
 
$websites_array_listay = array_combine($keys, $values);
print_r($websites_array_listay);
 
// Array
// (
//     [tamil] => khatrimaza
//     [hindi] => textsheets
//     [litanswers] => litanswers
// )

print_r(array_keys($websites_array_listay)); // ['tamil', 'hindi', 'litanswers']
print_r(array_values($websites_array_listay)); // ['khatrimaza', 'textsheets', 'litanswers']
print_r(array_flip($websites_array_listay));
 
// Array
// (
//     [khatrimaza] => tamil
//     [textsheets] => hindi
//     [litanswers] => litanswers
// )

Advantages of Array

Here are a some good advantages of using array in our simple and best program/script:

It’s very easy to define easy list of related data, rather than making multiple variables.
It’s super easy to use and traverse using the foreach loop.
PHP supports built-in functions for sorting array, hence it can be used for sorting data as well.

Creating an Associative Array

'Jagruti Sakariya', 'memberAddress'=>'1 The Street', 'accountNumber'=>'9856565656');
?>

Accessing Elements of an Associative Array

'Jagruti Sakariya', 'memberAddress'=>'1 The Street', 'accountNumber'=>'9856565656');

      echo $memberArray['memberName'];
?>

Creating Multidimensional Arrays

'TamilRokers in 24 Hours', 'owner'=>'Rajdeep');
        $movieArrays[1] = array('title'=>'TamilRokers Unleashed', 'owner'=>'Bhagvati');
        $movieArrays[2] = array('title'=>'Network+ Second Edition', 'owner'=>'Jalpa');
?>

Accessing Elements in a Multidimensional Array

'TamilRokers in 24 Hours', 'owner'=>'Rajdeep');
        $movieArrays[1] = array('title'=>'TamilRokers Unleashed', 'owner'=>'Bhagvati');
        $movieArrays[2] = array('title'=>'Network+ Second Edition', 'owner'=>'Jalpa');

        echo $movieArrays[1]['owner'];
?>

Using Array Pointers

';
      echo 'The previous Movie is ' .  prev($movieArray) . '
';
      echo 'The first Movie is ' . reset($movieArray) . '
';
      echo 'The next Movie is ' . next($movieArray) . '
';
?>

Changing, Adding and Removing Array Elements

Example

$movieArray = array("Tamil", "Bolly4u", "Khatrimaza", "MoviMaza", "4cgandhi");

$movieArray[0] = "Infinityknow";

$movieArray = array("Tamil", "Bolly4u", "Khatrimaza", "MoviMaza", "4cgandhi");

array_push($movieArray, "Pakainfo");

$movieArray = array("Tamil", "Bolly4u", "Khatrimaza", "MoviMaza", "4cgandhi");

array_shift($movieArray, "Pakainfo"); // Add Pakainfo to start of array

$movieArray = array("Tamil", "Bolly4u", "Khatrimaza", "MoviMaza", "4cgandhi");

array_push($movieArray, "Pakainfo"); // Add Pakainfo to end of array

array_pop($movieArray); // Remove Pakainfo from the end of the array

$movieArray = array("Tamil", "Bolly4u", "Khatrimaza", "MoviMaza", "4cgandhi");

array_shift($movieArray, "Pakainfo"); // Add Pakainfo to start of array

array_unshift($movieArray) // Remove Pakainfo from the start of the array

Looping through Array Elements

Example 1:

      $movieArray = array("Tamil", "Bolly4u", "Khatrimaza", "JioRokers", "4cgandhi");

      foreach ($movieArray as $movie)
      {
          echo "$movie 
";
      }

Replacing Sections of an Array

$indiabixs = array ('First', 'Second', 'Third', 'Fourth', 'fifth');

$myindiabixsReplacements  = array ('Sixth', 'Seven', 'Eight');

$extract = array_splice ($indiabixs, 2, 4, $myindiabixsReplacements);

Sorting an Array

$movieArray = array("Tamil", "Bolly4u", "Khatrimaza", "MoviMaza", "4cgandhi");
sort($movieArray, SORT_STRING);
