PHP | chunk_split() Function
The chunk_split() function is a built-in function in PHP. The chunk_split() function is used to split a string into smaller chunks of a specific length.
Syntax:
string chunk_split($string, $length, $end)
Parameters: This function accepts three parameters as shown in the above syntax and are described below:
- $string: This parameter specifies a string which is needed to be chunked.
- $length: This parameter specifies an integer which specifies the chunk length. That is the length of the chunked parts.
- $end: This parameter specifies the line ending sequence.
Return value: This function returns the string splitted into smaller chunks.
Examples:
Input : string = "geeksforgeeks"
length = 4
end = "."
