chr(): character from the specified ASCII value

$string="Let us print a variable ".chr(36)."my_var"; 

Let us print a variable $my_var 

echo "Let us print hash ".chr(35); //Output  Let us print hash #

echo " Less than ".chr(60);  // Output Less than <

<?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>";}

Example 2: Creating Special Character Symbols for HTML Entities

We can use *chr()* to create special HTML characters, such as © or ®, dynamically using their ASCII values:

echo "Copyright: " . chr(169) . " 2024"; // Outputs: Copyright: © 2024

Example 3: Using *chr()* for Character Ranges

We can create a range of characters using a loop:

for ($i = 65; $i <= 90; $i++) {
    echo chr($i) . " "; // Outputs A to Z
}
