php split string into array code example

Example 1: php split string along spaces

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

Example 2: php split string

<?php
// It doesnt get any better than this Example
$pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);

Example 4: split php

// split() function was DEPRECATED in PHP 5.3.0, and REMOVED in PHP 7.0.0.
// ALTERNATIVES: explode(), preg_split()

// explode()
// DESCRIPTION: Breaks a string into an array.
// explode ( string $separator , string $string , int $limit = PHP_INT_MAX ) : array
$pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2

// preg_split()
// DESCRIPTION: Split the given string by a regular expression.
// preg_split ( string $pattern , string $subject , int $limit = -1 , int $flags = 0 ) : array|false
$keywords = preg_split("/[\s,]+/", "hypertext language, programming");
print_r($keywords);
// output:
Array
(
    [0] => hypertext
    [1] => language
    [2] => programming
)

Example 5: php split string

explode(" ","Geeks for Geeks")

Example 6: php split string from end

You can use this following function
  
  function str_rsplit($string, $length)
{
    // splits a string "starting" at the end, so any left over (small chunk) is at the beginning of the array.
    if ( !$length ) { return false; }
    if ( $length > 0 ) { return str_split($string,$length); }    // normal split

    $l = strlen($string);
    $length = min(-$length,$l);
    $mod = $l % $length;

    if ( !$mod ) { return str_split($string,$length); }    // even/max-length split

    // split
    return array_merge(array(substr($string,0,$mod)), str_split(substr($string,$mod),$length));
}


$str = '123456789';
str_split($str,5); // return: {"12345","6789"}
str_rsplit($str,5);  // return: {"12345","6789"}
str_rsplit($str,-7); // return: {"12","3456789"}
