How to create a Set of Strings in PHP ?

Answer

In PHP, you can use an array to create a collection of unique strings.

✐ Examples

1 Create Set of Strings in PHP

In this example,

We create a new array named stringSet to store strings.
We add strings to the array using array syntax.
The resulting array contains unique strings in the order they were added.

PHP Program

<?php
// Create an array of strings
$stringSet = array();

// Add strings to the array
$stringSet[] = 'Apple';
$stringSet[] = 'Banana';
$stringSet[] = 'Cherry';

// Print the array
print_r($stringSet);
?>

Output

Array
(
    [0] => Apple
    [1] => Banana
    [2] => Cherry
)

2 Check if Set Contains a String

In this example,

We use the in_array function to check if a specific string exists in the array.
The in_array function returns true if the string is in the array, otherwise false.

PHP Program

<?php
// Check if the array contains a string
$containsBanana = in_array('Banana', $stringSet);
echo 'Array contains Banana: ';
var_export($containsBanana);
?>

Output

Array contains Banana: true
