String copying and character modification with the assignment operator
The assignment operator can copy a string.
The copy is deep, so changes to the first string do not affect the second.
$firstName = "Thomas";\n$alias = $firstName;
Individual characters can be changed by treating a string like an array.
String positions use zero-based indexing.
$a = "hello";
$a[0] = "H";\n$a[5] = "!";
The string becomes "Hello!".

"The assignment operator can also be used to make copies of strings.\n\n1 $firstName = \"Thomas\";\n\n2 $alias = $firstName;\n\nIt is important to understand that this assignment makes a deep copy of the string. Changes to the first do not affect the second one. You can make changes to individual characters in a string by treating it like a zero-indexed array.\n\n1 $a = \"hello\";\n\n2 $a[0] = \"H\";\n\n3 $a[5] = \"!\";\n\n4 //a is now \"Hello!\""
