Key Moments - 2 Insights

Why does the print statement show text on the screen?

Because print sends the given string to the output immediately, as shown in execution_table step 1.

What happens if we remove the semicolon at the end?

PHP requires a semicolon to end statements; missing it causes an error and stops execution before output.

Full Transcript

This example shows how PHP uses the print statement to display text on the screen. The program starts, executes the print command which outputs the string Hello, world!, then ends. The print statement requires a semicolon at the end to work correctly. Changing the text inside print changes what appears on the screen. This is the simplest way to show messages in PHP.
