Example 2: Difference between echo and print statement in php
Source link:
https:
1. echo Statement
* we can write echo statement with parenthesis like 'echo()' or without parenthesis 'echo'.
* In the echo we can pass multiple variable in comma separated form to see the output like 'echo $a,$b,$c;'
* echo doesn’t return any value
* echo is faster then print
2. Print Statement
* we can write print statement with parenthesis like 'print()' or without parenthesis 'print'.
* In the print we can not pass multiple variable in comma separated form like echo.
* print statement always returns 1.
* print is slower than echo
Example 3: print in php
print_r("");
Example 4: php print_r
<pre>
<?php
$a = array ('a' => 'apple', 'b' => 'banana', 'c' => array ('x', 'y', 'z'));
print_r ($a);
?>
</pre>
