Tutorial: Decode and solve in PHP quoted-printable characters from plain emails

If you handle Mails in PHP they sometimes contain 8bit strings like =3D or =0A or =0D etc. when trying to get the plain text mail out of a HTML mail for example. The PHP engine brings a built-in function called quoted_printable_decode() to decode such strings and get the plain, normal looking mail in return.

Decode those bit strings

Let's take this example mail with these bit strings in it:

It's exactly how its supposed to be according to the manual except I changed=

the url of where the .js file is.

Another random mail line is here.

This code would be=

the source. Thanks!



> Mr. Example,

> =0D=0A> does your inserted script look like that

> =0D=0A> =0D=0A> website.url

With the function quoted_printable_decode we could decode now those =0A [...] chars like that:

<?php

$mailString = 'The mail from above';

$decodedMailString = quoted_printable_decode($mailString);



echo $decodedMailString;

?>

The output of the script would look like that now and those special characters got decoded:

It's exactly how its supposed to be according to the manual except I changed the url of where the .js file is.

Another random mail line is here.

This code would be the source. Thanks!
