How to use str_split() and Custom Join Function In PHP
The str_split() function splits a string into an array of characters. For joining, we can create a custom function that concatenates array elements. It will concatenate the array elements into a single string, adding the separator between elements, and returns the resulting string.
Example: This example shows the use of the above-explained approach.
<?php
// Original string
$string = "HelloWorld";
// Split the string into characters
$splitString = str_split($string);
echo "After Splitting\n";
print_r($splitString);
// Custom function to join array elements
function customJoin($array, $separator = "_") {
$joinedString = "";
foreach ($array as $element) {
$joinedString .= $element . $separator;
}
return rtrim($joinedString, $separator);
}
// Joining the characters
$joinedString = customJoin($splitString);
echo "\nAfter Joining\n";
echo $joinedString;
?>
Output
After Splitting
Array
(
[0] => H
[1] => e
[2] => l
[3] => l
[4] => o
[5] => W
[6] => o
[7] => r
[8] => l
[9] => d
)
