In PHP, concatenation refers to combining two or more strings. This can be achieved using the string concatenation operator (.) or by using the compound concatenation operator (.=).
Here are some examples:
1. Using the string concatenation operator:
$firstName = "John";
$lastName = "Doe";
$fullName = $firstName . " " . $lastName;
echo $fullName; // Output: John Doe
In this example, the two variables
$firstName and $lastName are concatenated with a space in between using the string concatenation operator (.).
2. Using the compound concatenation operator:
$greeting = "Hello";
$name = "Jane";
$greeting .= " " . $name;
echo $greeting; // Output: Hello Jane
In this example, the string stored in the
$name variable is appended to the string stored in the $greeting variable using the compound concatenation operator (.=).
Note that there are different ways to achieve string concatenation in PHP, but these are the most commonly used methods.
