print — Output a string
Description
print
( string $arg
) : int
Outputs arg.
print is not actually a real function (it is a
language construct) so you are not required to use parentheses
with its argument list.
The major differences to echo are that
print only accepts a single argument and always returns 1.
Parameters
arg- The input data.
Return Values
Returns 1, always.
Examples
Example #1 print examples
<?phpprint("Hello World");print "print() also works without parentheses.";print "This spansmultiple lines. The newlines will beoutput as well";print "This spans\nmultiple lines. The newlines will be\noutput as well.";print "escaping characters is done \"Like this\".";// You can use variables inside a print statement$foo = "foobar";$bar = "barbaz";print "foo is $foo"; // foo is foobar// You can also use arrays$bar = array("value" => "foo");print "this is {$bar['value']} !"; // this is foo !// Using single quotes will print the variable name, not the valueprint 'foo is $foo'; // foo is $foo// If you are not using any other characters, you can just print variablesprint $foo; // foobarprint <<<ENDThis uses the "here document" syntax to outputmultiple lines with $variable interpolation. Notethat the here document terminator must appear on aline with just a semicolon no extra whitespace!END;?>
Notes
Note:
