Spliting and storing string in an array php -

i have string

$descr = "hello test string"; 

what trying split string , store each word separated using space separate array index in php. should use

$myarray = preg_split("[\s]",$descr); 

expected outcome :

$myarray(1) : hello $myarray(2) : $myarray(3) : $myarray(4) : $myarray(5) : test $myarray(6) : string 

each number denotes array index

you need use explode() below:-

$myarray = explode(' ', $descr); print_r($myarray);

to re-index , lowercase each word in array this:-

<?php  $descr = "hello test string";  $myarray = explode(' ', $descr);  $myarray = array_map('strtolower',array_combine(range(1, count($myarray)), array_values($myarray))); print_r($myarray); 

output:-https://eval.in/847960

to how many elements there in array:-

echo count($myarray);
