PHP 5 echo and print statements

In PHP, there are two basic ways to output: echo and print.

In this chapter, we will discuss the usage of the two statements in detail and demonstrate how to use echo and print in examples.

PHP echo and print statements

The difference between echo and print:

  • echo - can output one or more strings
  • print - only allows outputting one string, and the return value is always 1

Tip:echo outputs faster than print. echo has no return value, while print has a return value of 1.

PHP echo statement

echo is a language construct. When using it, you can either omit the parentheses or add them: echo or echo().
