PRINT(3) 1 PRINT(3)
print - Output a string
SYNOPSIS
int print (string $arg)
DESCRIPTION
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.
PARAMETERS
o $arg
- The input data.
RETURN VALUES
Returns 1, always.
EXAMPLES
Example #1
print examples
<?php
print("Hello World");
print "print() also works without parentheses.";
print "This spans
multiple lines. The newlines will be
output as well";
print "This spans
multiple lines. The newlines will be
output 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 value
print 'foo is $foo'; // foo is $foo
// If you are not using any other characters, you can just print variables
print $foo; // foobar
print <<<END
This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon no extra whitespace!
END;
?>
NOTES
Note
Because this is a language construct and not a function, it cannot be called using variable functions.
