command line - PHP interactive CLI: Up and Down arrows for history -


i having bug involving php interactive cli program.

i add commands history using readline_add_history, , read them in using readline.

the bug if, using arrow key, scroll through history command 5 characters or longer, first character of command "sticks", , stay there, after keep using arrow keys scroll again. disappears after hit enter.

eg:

% hello <enter> % <up arrow key> % hello <down arrow key> % h <up arrow key> % hhello <down arrow key> % h <enter> % <up arrow key> % hello ** notice here h isn't read in command. **

where can view code involving arrow keys / command history? i've looked online resources on how readline handles arrow keys , history can't find anything.

my code this:

while(true) {  $command = readline( "\n%" );  .. stuff ..  readline_add_history( $command );  }

i have readline_completion_function isn't being called when use arrow keys.

there seems bug readline() , prompt field (tested php 5.5.9 ubuntu), if prompt field has 'non-printable' characters in it, \n, have used.

i having similar problems, when trying used esc codes color prompt, causes history function go haywire :(

example: $_command = readline("\033[32m php> \033[35m");

the prompt can have normal chars in it, if want history function work correctly, unfortunately.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
