chr()

chr function to print ASCII characters , here are some examples
$string="Let us print a variable ".chr(36)."my_var"; 
Output is
Let us print a variable $my_var 
Same way we can change the string and check the outputs
echo "Let us print hash ".chr(35); //Output  Let us print hash #
echo " Less than ".chr(60); // Output Less than <
We can use ord function to get ASCII value of any character
By using a PHP for loop we can print all the ASCII table numbers. Here is the simple code.

<?Php
$i=0;
echo "<table><tr><td>";
for($i==0;$i<=127;$i++){
echo " chr($i) = ".chr($i)."<br>";
if($i%20 == 0 and $i>19){echo "</td><td valign=top>";}
}
echo "</td></table>";
?>
The output of this is here
chr(0) =
chr(1) =  chr(2) =  chr(3) =  chr(4) =  chr(5) =
