Convert string to array php

how to convert a string in array in php i.e

$str="this is string";

should be like this

  arr[0]=this
  arr[1]=is
  arr[2]=string 

The str_split($str, 3); splits the string in 3 character word but I need to convert the string after whitespace in an array.

Use explode function

$array = explode(' ', $string);

The first argument is delimiter

explode() might be the function you are looking for

$array = explode(' ',$str);

There is a function in PHP specifically designed for that purpose, str_word_count(). By default it does not take into account the numbers and multibyte characters, but they can be added as a list of additional characters in the charlist parameter. Charlist parameter also accepts a range of characters as in the example.

One benefit of this function over explode() is that the punctuation marks, spaces and new lines are avoided.

$str = "1st example:
        Alte Füchse gehen schwer in die Falle.    ";

print_r( str_word_count( $str, 1, '1..9ü' ) );

/* output:
Array
(
    [0] => 1st
    [1] => example
    [2] => Alte
    [3] => Füchse
    [4] => gehen
    [5] => schwer
    [6] => in
    [7] => die
    [8] => Falle
)
*/

explode — Split a string by a string

Syntax :

array explode ( string $delimiter , string $string [, int $limit = PHP_INT_MAX ] )

• $delimiter : based on which you want to split string
• $string. : The string you want to split

Example :

// Example 1
$pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2

In your example :

$str = "this is string"; 
$array = explode(' ', $str);

You can achieve this even without using explode and implode function. Here is the example:

Input:

This is my world

Code:

$part1 = "This is my world"; 
$part2 = str_word_count($part1, 1);

Output:

Array( [0] => 'This', [1] => 'is', [2] => 'my', [3] => 'world');

here, Use explode() function to convert string into array, by a string

click here to know more about explode()

$str = "this is string";
$delimiter = ' ';  // use any string / character by which, need to split string into Array
$resultArr = explode($delimiter, $str);  
var_dump($resultArr);

Output :

Array
(
    [0] => "this",
    [1] => "is",
    [2] => "string "
)

it is same as the requirements:

  arr[0]="this";
  arr[1]="is";
  arr[2]="string";
