PHP - Relational operators

The main use of the relational operators is in control of conditional statements. thanks to these, we can decide which direction to continue the conditional statements, or for example, how many iterations of the cycle need to perform.

less than

par1 < par2

greater than

par1 > par2

less than or equal to

par1 <= par2

greater than or equal to

par1 >= par2

Equal to

par1 == par2

Not equal to

par1 != par2

Other pieces of example codes:

if ($i==10)
     break;
   else 
   {
     $i--;
   }

if ($y<5)
   $y = $y/ 3.14;    // y = 1.234

if ($i - 10 >0) $i = $i-5;

$y != 25

$a = 4 >= 2

($j + 10) <= 128
