Answer / suresh.chaluvadi
when u use print(),a value of 1 or 0 will be returned upon
success or failure of the the print command.where as echo()
just does what its told without letting u know whether or
not it worked properly.

Answer / sreedevi
print is a construct but it returns True on success
outputr False if it was unable to print the output string
echo is faster comparing with print .
print doesnot takes multiple parameters

Answer / binoyav
In answer #10 the following section is wrong
"
echo evaluate the string before send the output just like this
$a=10
echo "Value is $a"
output:- Value is 10
print 'Value is $a'
output:- Value is $a "
If we give double quotes instead of single quote this will work.

echo() is not actually a function (it is a language
construct) so you are not required to use parentheses with
it. In fact, if you want to pass more than one parameter to
echo, you must not enclose the parameters within parentheses.
print() is not actually a real function (it is a language
construct) so you are not required to use parentheses with
its argument list.
1. Speed. There is a difference between the two, but
speed-wise it
should be irrelevant which one you use. echo is marginally
faster
since
it doesn't set a return value if you really want to get down
to the
nitty gritty.
2. Expression. print() behaves like a function in that you
can do:
$ret = print "Hello World"; And $ret will be 1. That means
that print
can be used as part of a more complex expression where echo
cannot. An
example from the PHP Manual:
$b ? print "true" : print "false";
print is also part of the precedence table which it needs to
be if it
is
to be used within a complex expression. It is just about at
the bottom
of the precedence list though. Only "," AND, OR and XOR are
lower.
3. Parameter(s). The grammar is: echo expression [,
expression[,
expression] ... ] But echo ( expression, expression ) is not
valid.
This would be valid: echo ("howdy"),("partner"); the same
as: echo
"howdy","partner"; (Putting the brackets in that simple
example
serves
no purpose since there is no operator precedence issue with
a single
term like that.)
So, echo without parentheses can take multiple parameters,
which get
concatenated:
echo "and a ", 1, 2, 3; // comma-separated without
parentheses
echo ("and a 123"); // just one parameter with
parentheses
print() can only take one parameter:
print ("and a 123");
print "and a 123";

Answer / mink$
every thing in single quotes is treated as string and would
not be evaluated in either print or echo.

Answer / ramesh kumar jayaraman
In Php echo is a statement..it doesn't return any
value...And It is faster
because it does not return any value, but print which
always returns 1 and 0.
The print acts like a function and it can be used in complex
expressions.
but echo can not be used in this way.
