What are the potential pitfalls of using the explode function in PHP for separating specific strings?

One potential pitfall of using the explode function in PHP for separating specific strings is that it splits the string based on a single delimiter, which may not always be reliable if the delimiter appears elsewhere in the string. To solve this issue, you can use a regular expression with the preg_split function instead, allowing for more flexibility in the splitting process. 

$string = "Hello,world!This,is,a,test";
$parts = preg_split('/[,.!]/', $string);
print_r($parts);
