<?php
if ($a > $b) {
  echo "a is greater than b";
} else {
  echo "a is NOT greater than b";
}

Where did this $a and $b comes from ? have you assigned any value ? i don't see it in code.

<?php

if ($a > $b) {
    echo 'a is bigger than b';
}  esleif ($a == $b)  {
   echo 'a is equal to b';
}  else  ($a < $b) {
   echo 'a is smaller than b';
}

First of all, where did you set $a and $b ? With out such a variable how it works ?

The error is because

esleif

Spelling mistake, use else if

Fixed code

<?php

$a = 1;
$b = 100;

if ($a > $b) {
    echo 'a is bigger than b';
}  else if ($a == $b)  {
   echo 'a is equal to b';
}  else  ($a < $b) {
   echo 'a is smaller than b';
}

echo '<p>Value of $a = ' . $a . ' and value of $b = ' . $b . '</p>';

<?php
$cowsCanFly = 'no'; //try changing value to 'no'

if  ($cowsCanFly == 'yes' )

{ echo 'There is no time like the present '; }

if ($cowsCanFly == 'no' )

{ echo 'When in Rome, do as the Romans'; }

Code formatting is not proper.

<?php

$cowsCanFly = 'no'; //try changing value to 'no'

if  ($cowsCanFly == 'yes' ) {
   echo 'There is no time like the present '; 
}

if ($cowsCanFly == 'no' ) { 
    echo 'When in Rome, do as the Romans'; 
}

Good code, use { } even if it is only one line code, lets have some coding style everyone follow, so no one (me) get confused
