I think you need a seperate variable to hold the counter 

<?php
$a=5;
$num = 1;

for($i=1;$i<=$a;$i++){
   for($j=1;$j<=$i;$j++){
      echo $num++;  // echo and increment the counter
   }
   echo "</br>";
}
?>

just few modification needed

$number = 1; // counter
$a=5;
for($i=1;$i<=$a;$i++){
   for($j=1;$j<=$i;$j++, $number++){ // increment number 
      echo $number. ' '; // space 
   }
   echo "</br>";
}
