Phpecho output string function details _ PHP Tutorial

Phpecho output string function details. Copy the code as follows: echoasd; string echoads $ c; string + variable echoads $ c; string asd $ c is not the variable echosd. vs; echosd, vs; echo $. $ B; The code is as follows:

Echo "ads $ c"; // String + variable
Echo 'ads $ C'; // string asd $ c is not a variable
Echo "sd". "";
Echo "sd", "";
Echo $;
Echo $ a. $ B;
Echo $ a, $ B;
Echo $ a. $ B. $ c;
Echo $ a, $ B, $ c;
Echo "kaskd {$ c} asd ";
Echo "kakskd {$ arr ['Lo']}";
Echo "kakskd {$ obj-> }";
Echo "kaskd". $ c. "kasd ";
Echo "kaskd". $ arr ['Lo']. "kasd ";
Echo "kaskd". $ obj-> a. "kasd ";
Echo "kaskd". func ($ c). "kasd ";
Echo "kaksk". ($ a + 1). "dkkasd ";
Echo $ c. "jaksd ";

// Php multiline output method
Echo < This uses the "here document" syntax to output
END;
// Abbreviated output
　　

The code is as follows:

Echo "Hello World ";

Echo "This spans
Multiple lines. The newlines will be
Output as well ";

Echo "This spans \ nmultiple lines. The newlines will be \ noutput as well .";

Echo "Escaping characters is done \" Like this \".";

// You can use variables inside of an echo statement
$ Foo = "foobar ";
$ Bar = "barbaz ";

Echo "foo is $ foo"; // foo is foobar

// You can also use arrays
$ Baz = array ("value" => "foo ");

Echo "this is {$ baz ['value']}! "; // This is foo!

// Using single quotes will print the variable name, not the value
Echo 'foo is $ Foo'; // foo is $ foo

// If you are not using any other characters, you can just echo variables
Echo $ foo; // foobar
Echo $ foo, $ bar; // foobarbarbaz

// Some people prefer passing multiple parameters to echo over concatenation.
Echo 'it', 'string', 'was', 'Made ',' with multiple parameters. ', chr (10 );
Echo 'this'. 'string'. 'was'. 'Made '.' with concatenation. '. "\ n ";

Echo < This uses the "here document" syntax to output
Multiple lines with $ variable interpolation. Note
That the here document terminator must appear on
Line with just a semicolon. no extra whitespace!
END;

// Because echo does not behave like a function, the following code is invalid.
($ Some_var )? Echo 'true': echo 'false ';

// However, the following examples will work:
($ Some_var )? Print 'true': print 'false'; // print is also a construct,
// It behaves like a function, so
// It may be used in this context.
Echo $ some_var? 'True': 'false'; // changing the statement around
?>
