<?Php
$i=0;
echo "<table><tr><td>";
for($i==0;$i<=127;$i++){

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
}
