PHP echo and print
In PHP, both echo and print are used to output data to the browser,
but there are some differences between them. Here’s a breakdown of how
they differ:
1. echo
Purpose: echo is used to output one or more strings to the browser.
Syntax: echo expression1, expression2, ...;
Performance: Slightly faster than print because it does not return a value.
Return Value: echo does not return a value. It simply outputs the string(s) to the browser.
Example: echo "Hello, World!";
2. print
Purpose: print is used to output a string to the browser.
Syntax: print expression;
Performance: Slightly slower than echo because it has to return a value.
Return Value: print returns 1, which means it can be used in expressions.
Example: print "Hello, World!";
Comparison
Number of Parameters:
echo can accept multiple parameters separated by commas.
print can only take a single parameter.
Return Value:
echo does not return a value.
print returns 1, which can be used in expressions.
Performance:
echo is marginally faster than print because it doesn’t need to return a value.
Usage Context:
Use echo when you need to output multiple strings or when performance is a consideration.
Use print if you need to check the success of the output operation (e.g., when using it in a condition or expression).
