echo

statement can be used to print the string, multi-line strings, escaping characters, variable, array, etc. • printing string

echo "Hello friends!\n";

• printing multi line string

echo "How are you ?  
this is multi line  
text !\n";

• printing escaping characters

echo "Hello \"Hello\" Hello\n";

• printing variable value ( only DOUBLE quetes can parse variables )

$num= 17;  
echo "num = $num\n";  
// or => echo "num = ".$num."\n";
// or => echo 'num = '.$num."\n";

• printing number without quotes

echo 10;

• printing multiple parameters

echo "red"," yellow"," black";

• echo can be used with or without parentheses: echo(), and echo.

echo ("function\n");

• Text inside double quotes can include single quotes as part of the text. The opposite is also possible.

echo "My name is 'Anton'\n";
echo 'My name is "Anton"';

➤ PHP

print

statement works exactly the same way except that the print statement can only output one parameter, and always returns 1. • returns 1

$result = print"Hello\n";
echo "result = $result"; // output: 1

•

print

can take only one argument

print "hello","world"; // error
