"Recall the main purpose of PHP is as a scripting language to serve dynamic webpages. However, it does support input and output from the standard input/output. There are several ways to print output to the standard output. The keywords print and echo (which are aliases of each other) allow you to print any variable or string. PHP also has a printf() function to allow formatted output. Some examples:\n\n1 $a = 10;\n\n2 $b = 3.14;\n\n3\n\n4 print $a;\n\n5 print \"The value of a is $a\n\n\";\n\n6\n\n7 echo $a;\n\n8 echo \"The value of a is $a\n\n\";\n\n9\n\n10 printf(\"The value of a is %d, and b is %f\n\n\", $a, $b);\n\nThere are also several ways to perform standard input, but the easiest is to use fgets"
