PHP difference between echo,print and printf

Echo, print and printf these three are used for printing the text. Here i am going to explain the difference between these three

echo
----
*) it's a construct.
*) allow multiple parameters
*) does not return any value

print
-----
*) it's also a construct.
*) do not support multiple parameters
*) return true if it success or false if it fail

printf
------
*) it's a function not a construct
*) allow multiple parameters

optimize php code

Here I am going to write about the common steps to optimize php coding

*) Try to avoid using count() in a loop
(ex) for ($i=0;$i<count($array);$i++) {
}
In this above example the count function called in loop, so it's make delay your page load.

so just follow this
for ($i=0,$n=count($array);$i++) {
}

*)  echo statement
   use ' instead of "
   use , instead of .
This two will increase you page load.
