Q5.Which PHP function is used to output one or more strings?print_r()echo()print()sprintf()

The PHP function used to output one or more strings is echo(). Here's how you can use it:

echo "Hello, World!";

In this example, "Hello, World!" is the string that gets outputted. You can also output more than one string like this:

echo "Hello, ", "World!";

In this case, "Hello, " and "World!" are two separate strings that get outputted.

Note: While print() and print_r() can also be used for output, echo() is more commonly used because it can output one or more strings. print() can only output one string at a time and print_r() is typically used for human-readable information about a variable.
