Johs answered on JPopularity 6/10 Helpfulness 5/10 Contents answer php explode empty string. If separator values appear at the start or end of string, said values will be added as an empty array value either in the first or last position of the returned array respectively. It appears that explode() returns an empty array (instead of an array with string in it) if limit is negative and delimiter contains a value that is not contained in string. Both methods are simple and effective.Bjorn dot Wiberg at its dot uu dot se Description: You can use either the `array_filter()` function or a loop to achieve this. In the last array, since a negative value was passed the last element was removed and all the other values were passed as an array. If separator contains a value that is not contained in string and a negative limit is used, then an empty array will be returned, otherwise an array containing string will be returned. In the first array, since the limit value was less than the number of elements all the remaining elements were passed in the last element. In this guide, you have learned how to remove all empty values when you explode a string using PHP.

We can use this function along with `explode()` to remove empty values from the resulting array. Syntax: Example-1: Using empty string delimiter Output: Example-2: Using a particular character as delimiter Output: Example-3: Using the list() function.
