explode() is a built-in PHP function that gives us a split string in PHP. The explode() method separates a string depending on a string delimiter, that is, whenever the delimiter character appears in the string. This function returns an array containing the split strings from the original string.
The explode function accepts three parameters, two of which are required and one of which is optional.
- Separator: This character specifies the critical points or points at which the string will split, i.e., whenever this character appears in the string, it represents the end of one array element and the beginning of another.
- OriginalString: The string that will be divided into an array.
- NoOfElements: This is optional. It is used to indicate the array’s number of items. Any integer can be used as this argument ( positive, negative, or zero)
- Positive (N): Passing a positive value for this argument indicates that the array will have this many entries. If the number of elements after separation about the separator exceeds this amount, the first N-1 items stay unchanged, and the final element is the entire remaining string.
- Negative (N): If a negative value is supplied as a parameter, the array’s final N elements will be trimmed off and the remainder will be returned as a single array.
If this option is set to zero, the array produced will only contain one entry, which is the whole string.
If this option is omitted, the array returned includes the total number of elements generated after the separator has been used to separate the text.
The explode() method returns an array of strings as its return type.
