What are the differences between echo and print in PHP?
Both echo and print are used to output data in PHP, but they have subtle differences:
- echo: Can take multiple parameters (comma-separated), does not return a value, slightly faster
- print: Takes only one argument, always returns 1, can be used in expressions
echo "Hello", " World"; // Works
print "Hello World"; // Works
$result = print "test"; // $result is 1
