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:
1 2 |
$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:
1 2 |
$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.
