How to convert string to array using PHP

A string is a set of character. You can split a string to an array using PHP built-in explode() function.

Now I am going to convert the array elements into string from an example array. The explode() function can breaks a string into an array. This function is binary-safe.

Syntax

explode(separator,string)

You need to provide two parameter here. But you can use another optional parameter.

1. Separator: This parameter specifies where to break the string. It cannot be an empty string.

2. String: This parameter indicate from where you want to split.

3. Limit: It specifies the number of array elements to return. This is an optional parameter.

Note: you can use variable in the replacement of parameters.

Example: Convert string to array

Example 1: Break string by space

<?php
//input string
$string = "color1 color2 color3 color4 color5 color6 color7 color8";
//breaking string
$color = explode(" ", $string);
//showing results
echo $color[0]; // Output: color1
echo $color[1]; // Output: color2

Example 2: Break string by  comma

<?php
//input string
$string = "color1, color2, color3, color4, color5, color6, color7, color8";
//breaking string
$color = explode(",", $string);
//showing results
echo $color[2]; // Output: color3 
echo $color[3]; // Output: color4 
//showing result
print_r($color);

Output:

Array (

[0] => color1

[1] => color2

[2] => color3

[3] => color4

[4] => color5

[5] => color6

[6] => color7

[7] => color8 )

The output methods I provide avobe may not the proper methods while working with projects. You need to use foreach loop to perfect results. Please see the example below.

Example 3: Showing converted output with foreach loop

<?php
//input string
$string = "color1 color2 color3 color4 color5 color6 color7 color8";
//breaking string
$color = explode(" ", $string);
//generating output
foreach($color as $output){
    echo $output.'<br>';
}

Output:

color1

color2

color3

color4

color5

color6

color7

color8
