  • PDF_get_buffer()

    (PHP 4 >= 4.0.5, PECL pdflib >= 1.0.0)

    Get PDF output buffer

    说明

    PDF_get_buffer(resource $p): string

    Fetches the buffer containing the generated PDF data.

    This function can only be used when you are writing a file to memory and not to a physical file. Otherwise you will get an error like this one: Don't fetch buffer contents when writing to file.
    If you plan to use get_buffer() you have to call open_file() with an
    empty filename.
