Introduction to PHP
Strings
Strings are used to represent textual information and can be defined within single ' ' or double " " quotes.
main
Strings can contain any characters, including letters, digits, and special symbols.
String Concatenation
Concatenation in PHP is used to join strings together into one string. The concatenation operator . (dot) is used for this purpose:
main
The code above defines two variables, $firstName and $lastName, with values "John" and "Doe" respectively. It concatenates them into $fullName using the dot operator and then outputs the full name "John Doe" using echo.
Using Single and Double Quotes
You can use both '(single) and "(double quotes) to define strings. They have some differences in how they handle variables and special characters.
Double quotes allow variables to be directly used within the string and support escaping special characters:
main
Single quotes treat everything inside them as literal text, ignoring variables and special characters:
main
Завдання
- Assign any name to the variable
$name. - Concatenate the strings using the
.operator so that running the code outputs the greeting"Hello,SomeName!".
Завдання
- Assign any name to the variable
$name. - Concatenate the strings using the
.operator so that running the code outputs the greeting"Hello,SomeName!".
