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 = "neveropen"
length = 4
end = "."
Output: Geek.sfor.Geek.s.
Input: string = "Twinkle bajaj"
length = 2
end = "*"
Output: Tw*in*kl*e *ba*ja*j*
Below programs illustrate the chunk_split() function in PHP:
Program 1:
PHP
<?php // PHP program to illustrate the // chunk_split function $str = "Twinkle bajaj"; echo chunk_split($str, 2, "*"); ?> |
Output:
Tw*in*kl*e *ba*ja*j*
Program 2:
PHP
<?php // PHP program to illustrate the // chunk_split function $str = "neveropen"; // Returns a string with a '.' // placed after every four characters. echo chunk_split($str, 4, "."); ?> |
Output:
geek.sfor.geek.s.
Program 3:
PHP
<?php // PHP program to illustrate the // chunk_split function $str = "abcd"; echo chunk_split($str, 4, "@@"); ?> |
Output:
abcd@@
Program 4:
PHP
<?php // PHP program to illustrate the // chunk_split function // If specified length is more than // string length, then added at the // end. $str = "abcd"; echo chunk_split($str, 10, "@@"); ?> |
Output:
abcd@@
