How can PHP be used to save a JPEG file from HEX data?

To save a JPEG file from HEX data in PHP, you can use the `file_put_contents` function along with `hex2bin` to convert the HEX data to binary before saving it as a JPEG file. First, convert the HEX data to binary using `hex2bin`, then use `file_put_contents` to save the binary data as a JPEG file. 

<?php
$hexData = 'FFD8FFE000104A46494600010101004800480000FFED003E41646F626520496D616765526561647973202852292032303030FFDB008400080606070605080707070909080A0C140D0C0B0B0C1912130F141D1A1F1E1D1A1C1C20242E2720222C231C1C2837292C303134343C2E3339372D3A2E2027393C2E333C3C3C3CFFFFDB0084000909090C0B0A0C180D0D1832211C2132323232323232323232323232323232323232323232323232323232323232323232323232323232323232323';
$binaryData = hex2bin($hexData);
file_put_contents('image.jpg', $binaryData);
?>
