How to output the entire array in php

Sample code:
<?php $arr = array('apple', 'banana', 'orange', 'peach'); print_r($arr); ?>

Array ( [0] => apple [1] => banana [2] => orange [3] => peach )
Method 2: Use the var_dump() function
var_dump() function can be printed out in PHP Functions with details such as variable type, length, value, etc. It works not only for arrays, but also for other variable types.
Sample code:
<?php $arr = array('apple', 'banana', 'orange', 'peach'); var_dump($arr); ?>
Output result:
array(4) { [0]=> string(5) "apple" [1]=> string(6) "banana" [2]=> string(6) "orange" [3]=> string(5) "peach" }
Method 3: Use foreach() loop
We can also use foreach() loop to output the entire array. This method is more flexible and can control each element of the output array.

<?php $arr = array('apple', 'banana', 'orange', 'peach'); foreach ($arr as $value) { echo $value . '<br>'; } ?>
