Program 1: The following program demonstrates the imap_binary() function.

PHP

<?php 
  
$string = "horje"; 
$eightBitData = imap_binary($string); 
  
// Output the result 
echo "Original data: $string\n"; 
echo "Converted base64 data: $eightBitData\n"; 
  
?>

Output:

Original data: horje
Converted base64 data: Z2Vla3Nmb3JnZWVrcw==

Program 2: The following program demonstrates the imap_binary() function.

PHP

<?php 
  
$utf7data1 = "&ZeVnLIqe-"; 
$utf7data2 = "&BfAEEAbABlAG4ALwA-"; 
  
// Check if the imap_binary() function exists 
if (function_exists("imap_binary")) { 
    $eightBitData1 = imap_binary($utf7data1); 
    $eightBitData2 = imap_binary($utf7data2); 
  
    // Output the results 
    echo "Original UTF-7 data 1: $utf7data1\n"; 
    echo "Converted 8-bit data 1: $eightBitData1\n\n"; 
  
    echo "Original UTF-7 data 2: $utf7data2\n"; 
    echo "Converted 8-bit data 2: $eightBitData2\n"; 
} else { 
    echo "imap_binary() function is not available"
        . " in this environment.\n"; 
} 
  
?>

Output:

Original UTF-7 data 1: &ZeVnLIqe-
Converted 8-bit data 1: JlplVm5MSXFlLQ==
Original UTF-7 data 2: &BfAEEAbABlAG4ALwA-
Converted 8-bit data 2: JkJmQUVFQWJBQmxBRzRBTHdBLQ==
