Of course it is possible to call a PHP-function inside an echo statement. The function will be executed and returns a value. This value then is used in the echo statement.
For example:
echo "Ferengi-Rule #1: ", ferengi_rule(1), "\n";
echo "Random: ", ferengi_rule(0), "\n";
function ferengi_rule($number)
{
$rules = array(
1 => "Once you have their money, never give it back.",
2 => "You can't cheat an honest customer, but it never hurts to try.",
3 => "Never buy anything for more than is absolutely necessary.",
4 => "Sex and profit are the two things that never last long enough."
// ...
);
if( isset($rules[$number]) )
{
return $rules[$number];
}
else
{
return array_rand($rules);
}
}
You could use a function like this:function isPalindrome($string) {$string = strtolower($string);return (strrev($string) == $string) ? true : false;}and then to check a palindrome call an if statement like so:if(isPalindrome($test)) {echo $test.' is a palindrome';}else {echo $test.' is not a palindrome';}
A simple function call <html> <body> <?php if(isset($_POST['button'])) { setValue(); // Function is called } function setValue() { echo "<br>The button property to call PHP function works"; // Your code here } ?> <input type="submit" name="button" onclick=<?php $_SERVER['PHP_SELF']; ?> /> </body> </head>
displaying a variable in php using echo statement? <?php $name="ram"; //declaring and defining the variable echo "$name"; //printing the variable using echo command ?>
The print function is slightly more dynamic than the echo function by returning a value, and the echo function is slightly (very slightly) faster. The printf function inserts dynamic variables/whatever into wherever you want with special delimiters, such as %s, or %d. For example, printf('There is a difference between %s and %s', 'good', 'evil') would return 'There is a difference between good and evil'.
ord() is the function you need. echo ord(' '); Would output the number 32.
echo function();

'esac' is the end identifier for the 'case' selection statement. For example, case $i in Y|y) echo said yes ;; N|n) echo said no ;; *) echo $i is a bad answer esac
A wolf's howl doesn't have an echo because of the frequency. Also a duck's quack doesn't echo (Actually a duck's quack will echo. Google Mythbusters - they did research on this.)
That would be an echo.
echo will not return output when using parenthesis because echo is not a function like print. echo is a language construct. The benefit to using echo over the print function is speed, plus you can separate data types using comma's rather than periods.Example:echo 'This is a string ' , $variable , ' ending string';is the same (but faster) as:print('This is a sting' . $variable . ' ending string');
A php function is coding that can be called multiple times to repeat a task. function add_numbers($num1,$num2) { return $num1 + $num2; } this would add two numbers together when called, so when you call $x = add_numbers(1,3); echo $x; //displays 4
Continuously repeating echoes in a room are known as reverberation.Where the echo is distinct, it is just an echo
