[BNM] Advice on Comparing base64 encoded images in PHP please.

[joseppi c]

Hi,

I am having to store jpeg Images as base64 encoded strings.

I would like to do a comparison between two images to see if they differ.

Should I just do a:

if(strcmp($imageStr1, $imageStr2))
{
 //do stuff
}

Or speed-wise is it better to compare the MD5 result of each string:

if(md5($imageStr1) != md5($imageStr2))
{
 //do stuff
}

Or does it matter?


Thanks,

Joe.
