Echo and print both functions are used to print output in PHP.
Echo & print statement are same but there is a little difference is 
echo print multiple variable in single echo statement and echo return
zero(0) value and Print statement print only single variable at a 
time and its return one(1) value.
Simple Code Example:
     <?php 
	echo ("Php is scripting language.");
     	print ("Php can be used with or without parenthesis."); 
     ?>
Another Code Example with variable:
     <?php     
	echo ($abc. "Testing". $xyz);
     	print ("Safcode.");
     ?>
