Solution: Use the PHP count() as well as sizeof() length function

You can easy to use the get length of the total results find via PHP count() as well as sizeof() method to fetch the number of all the data elements read as well as find the values in an array. here available my prev Article The count() function and sizeof() function returns Boolean value like as 0 for a variable as a data that has been simply mode of the initialised with data value null or an empty array, so it might also Boolean value return 0 for a variable that are not update.as well We can basically step by step to understand the below Flowchart.

// display of Printing players total array size
echo 'Total number of players in the $players array is - ' . count($players);
echo "<br>";
echo 'Total number of players in the $players array is - ' . sizeof($players);
?>

Results:

Total number of players in the $players array is = 7
Total number of players in the $players array is = 7

How to create an Array in PHP?

An empty array

<?php

$emptyArray = array();

?>

Single dimensional array

<?php

$players = array(“Virat”, “Sachin”, “Dhoni”);
$arrLength = count($players);

// loop through the array
for($i = 0; $i < $arrLength; $i++) {
    echo $players[$i];
    echo "</ br>";
}

?>

Associative array

<?php

$players = array("Virat"=>"Batsmen", "Bhmrah"=>"Bolawer", "Sachin"=>"Batsmen");

// loop through get a associative all the array data value as well as retrive key value pairs
foreach($players as $key => $value) {
    echo "Key=" . $key . ", Value=" . $value;
    echo "</br>";
}

?>

Two dimensional array

<?php

// two-dimensional array definition
$players = array
  (
  array("Virat","Batsmen",8),
  array("Bhmrah","Bolawer",12),
  array("Sachin","Batsmen",20)
  );

// two-dimensional array iteration
for ($row = 0; $row < 3; $row++) {
  echo "<p>Row number $row</p>";
  echo "<ul>";
  for ($col = 0; $col < 3; $col++) {
    echo "<li>".$players[$row][$col]."</li>";
  }
  echo "</ul>";
}

?>

Via PHP loop

<?php

$players = array();
for ($i = 0; $i < $count; $i++) {
    $players[$i] = array
        ( $playerName[$i]
        , $playerType[$i]
        );
}

?>
