$beforeDot = explode(".", $string)[0];
This is what I'm attempting to do, except that it returns syntax error. If there is a workaround for a one liner, please let me know. If this is not possible, please explain.

Answer: Use the PHP array_shift() function You can use the PHP array_shift() function to remove the first element or value from an array. The array_shift() function also returns the removed value of array. However, if the array is empty (or the variable is not an array), the returned value will be NULL .
The explode() function breaks a string into an array. Note: The "separator" parameter cannot be an empty string. Note: This function is binary-safe.
There are several methods to get the first element of an array in PHP. Some of the methods are using foreach loop, reset function, array_slice function, array_values, array_reverse, and many more. We will discuss the different ways to access the first element of an array sequentially.
Use current(), to get first position after explode:
$beforeDot = current(explode(".", $string));
