How can the use of explode in PHP affect the structure of an array and what should be considered when using it?

Using the explode function in PHP can affect the structure of an array by splitting a string into an array based on a specified delimiter. When using explode, it's important to consider the delimiter being used to ensure the string is split correctly. Additionally, handling the resulting array properly is crucial to avoid unexpected behavior in your code.

$string = "apple,banana,orange";
$fruits = explode(",", $string);
print_r($fruits);
