What are the Key Differences Between `echo` and `print` in PHP?

Understanding the Differences Between echo and print in PHP

Despite the common misconception of being duplicates, echo and print are distinct functions in PHP with notable differences.

1. Speed

Although negligible in practical use, echo marginally outperforms print in terms of speed.

2. Expression Handling

Unlike print, echo cannot be used within complex expressions. While print can be assigned a return value, echo cannot. This limitation restricts echo to mere output purposes.

3. Parameters

echo can accept multiple parameters that are concatenated during output, allowing for more flexibility in formatting. In contrast, print can handle only a single parameter.

4. Syntax

echo employs a more straightforward syntax:

echo "Hello World";

Print requires parentheses if used with an expression:

print ("Hello World");
