How does the combination of explode and implode functions work in PHP for removing a character from a string?

To remove a character from a string in PHP, you can use a combination of the explode and implode functions. First, you can use explode to split the string into an array of characters, then use array_filter to remove the character you want to delete, and finally, use implode to join the array back into a string. 

$string = "Hello World";
$charToRemove = "o";

$charArray = str_split($string);
$filteredArray = array_filter($charArray, function($char) use ($charToRemove) {
    return $char !== $charToRemove;
});

$newString = implode("", $filteredArray);

echo $newString; // Output: Hell Wrld
