Can echo() alter the content of a variable in PHP?

No, echo() cannot alter the content of a variable in PHP. Echo is used to output strings or variables to the screen, but it does not modify the actual value of the variable itself. To alter the content of a variable, you would need to use assignment operators like =, +=, -=, etc. 

$variable = "Hello";
echo $variable; // Outputs: Hello

$variable = "World";
echo $variable; // Outputs: World
