Splitting a PHP string using the explode() function
The explode() function converts a string into an array by a separator, where the required parameters are delimiter and string.
- separator: the character that specifies breakpoints or points at which the string will be split. When this character occurs in a string, it symbolizes the end of one array element and the beginning of another.
- string: the string to be split into an array
- limit (optional): the limit specifies the number of array elements to return. The parameter can be any integer: positive, negative, or zero. If positive, the array will contain the set number of elements. If the number of elements after the delimiter split exceeds this value, the first elements remain the same, and the last element is the entire remaining string. If negative, then the last element of the array will be truncated, and the rest of the array will be returned as a single array. If zero, the returned array will contain only one element, i.e., the entire string. If this parameter is not specified, the returned array has the total number of elements after separating the string with the separator.
