    convert_uuencode — Uuencode a string

    Опис

    convert_uuencode(string $string): string

    convert_uuencode() encodes a string using the uuencode algorithm.

    Uuencode translates all strings (including binary data) into printable characters, making them safe for network transmissions. Uuencoded data is about 35% larger than the original.

    Зауваження: convert_uuencode() neither produces the begin nor the end line, which are part of uuencoded files.

    Параметри

    @Craig's note: base64_encode() is better suited for that. In fact, it produces smaller output and operates slightly faster. I did a little benchmark -- here are my findings:

    File: JPG, 631614 bytes

    == Base64 ==
    execution time: 0.0039639472961426 secs
    output length: 842152

    == UUencode ==
    execution time: 0.004105806350708 secs
    output length: 870226

    note that using base64 or uuencode to store data in a database is pretty useless. if you properly escape your data and use a binary field (BLOB etc) there is no problem.
