To convert a PHP variable to Base64 String we can make use of base64_encode() function,

Syntax : String base64_encode(String $var);

File : php_encode_example.php Language : PHP
<?php

    $data = "This is the text to be converted to Base64 string @ $ % ^ & * #@ %& &* &^( " ;

    $base64EncodedData = base64_encode($data);
  
    echo $base64EncodedData;

?>
Output : VGhpcyBpcyB0aGUgdGV4dCB0byBiZSBjb252ZXJ0ZWQgdG8gQmFzZTY0IHN0cmluZyBAICQgJSBeICYgKiAjQCAlJiAmKiAmXigg

Similarly, we can make use of base64_decode() function to decode a Base64 encoded text to plain text,

Syntax : String base64_decode(String $Base64encodedString);

File : php_encode_example.php Language : PHP
<?php

    $Base64encodedData = "VGhpcyB0ZXh0IHdhcyBiYXNlNjQgZGVjb2RlZCB1c2luZyBiYXNlNjRfZW5jb2RlKCkgZnVuY3Rpb24=" ;

    $plainText = base64_encode($Base64encodedData);
  
    echo $plainText;

?>
Output : This text was base64 decoded using base64_encode() function
