How to Insert String Into String In Laravel?

3 minutes read

To insert one string into another string in Laravel, you can use the concatenation operator (.) to combine two strings together.

For example, if you have a variable $name with the value "John" and you want to insert it into a sentence, you can do so like this:

$name = "John";
$sentence = "Hello, my name is " . $name . "!";

This will result in $sentence containing the value "Hello, my name is John!".

You can also use double quotes and curly braces to directly insert a variable into a string like this:

$name = "John";
$sentence = "Hello, my name is {$name}!";

This will achieve the same result as the previous example.

Overall, inserting a string into another string in Laravel is a simple process that can be done using concatenation or the curly braces method.
