We can use the PHP concatenation operator (.) to join or combine two strings together in PHP. This operator is exactly designed for strings.
There are two string operators :
- Concatenation operator (‘.’) – Concatenation of str1 and str2
Example: $str1 . $str2
- Concatenating assignment operator (‘.=’) – Appends the str2 to the str1
Example: $str1 .= $str2
