PHP explode Function Example: Splitting a String with No Delimiter

The given code snippet uses the 'explode' function in PHP to split a string into an array.

In this case, the string being split is 'blog2.jsgreen.top', and the delimiter used is ','. Since there are no commas in the string, the resulting array will contain only one element: 'blog2.jsgreen.top'.

Therefore, the value of the '$domains' variable will be an array with a single element: ['blog2.jsgreen.top'].
