In PHP array length Example, array is an execution of an ordered Map. as well as A data map is an abstract data type of some key value term sets. this is one type of an interface, a arrangement.
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.

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] ); } ?>
Example : PHP count() Function
Return the total number of data elements in an array like below example: array length in php
<!DOCTYPE html> <html> <body> <?php $players=array("Virat","Sachin","Dhoni"); echo "<pre>"; echo count($players); echo "<br/><hr/>"; print_r($players); echo "<pre>"; ?> </body> </html>
Results
3 ---------------------- Array ( [0] => Virat [1] => Sachin [2] => Dhoni )
