Ok, even when trying to use the mysqli_statement->bind_params() and
mysqli_statement->send_long_data() to pass larger blob data chunks through,
I am still hitting a form of timeout - from the mysqli_statement->errorno,
and error string:
["errno"]=> int(2006)
["error"]=> "MySQL server has gone away"
Will have to try find out what error no. 2006 refers to - bit of an
irritation that it's a possibly too commonly used search term, in terms of
being a relatively recent year, etc...<smile>

mysqli_real_escape_string() function?
Thanks - looks pretty much exactly what I want to try achieve, so will try
modd'ing my code/script and see if works...<smile>
Also nice to maybe use the actual parameter binding for a change instead
of just building up sql statement strings using sprintf() etc. - know
better practice anyway.
Stay well

What with trying to store image data in mySQL database, I am saving the
results of fread() function carried out using the file handle returned
from fopen(), with the "rb" argument to tell it the file is for binary
reading.
Either way, for example, this specific image file is a 2.1Mb PNG file,
and mySQL server on my local, windows development machine seems to lock
up roundabout when I tell it to carry out the mysqli_real_escape_string()
function on the value of the variable that now contains the data read
from the physically uploaded file, and just wondering if this could be
something like a process overload, etc., and whether should just try
taking out the string real escaping for now, or whether that's likely to
cause problems, or should I try something like splitting the file's data
into more manageable size chunks, carry out the string escaping on those
chunks one at a time, with even a possible form of pause inbetween, and
then re-append them together before writing them to the database, or
should I maybe just implement at least a form of file size limit, which
might be an issue if the user will insist on certain image sizes,
resolutions, etc. etc.?
Thoughts/suggestions?
Not really windows specific, php-database could fit better for this
question but here is what you should do:
