[PHP] Re: Alternatives to Flush()
Ron Stagg wrote on 24/03/04 22:02: I have a particular PHP web page that can take over an hour to process. When visitors come to this page, I want the code to redirect them to a separate page at my site. After the redirection, I want the PHP script to continue operating on its own until the process is complete. I am attempting to implement this is by sending a Location header to the client. This header is sent out near the top of the script. After sending the header, I call Flush(), then the script continues into the heavy lifting. Finally, the script quietly terminates with an exit call. Neither the flush() or ob_flush() calls are working (I even tried calling them both). Regardless of what I do, the server will not send the Location header until the script has completely terminated. It appears that my hosting provider has Flush() disabled. I have thought about using Chron to accomplish this. However, the smallest Chron resolution is minutes. This could cause the visitor to wait for up to a minute before Chron wakes up and starts working on the process. There has got to be a better way. Does anybody have any recommendations? Thanks, Ron I could be completely misreading the issue here, but it is perfectly possible to use a Location header redirect in combination with further script execution in the background using PHP's register_shutdown_function(). The specifics and complexity of your actual script are unknown to the list, so I can only refer you to the manual (and the user contributed notes) for further inspiration and investigation: http://www.php.net/manual/en/function.register-shutdown-function.php HTH, Dirk Maetens PHP hobbyist -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This in accordance to the most recent PHP documentation, which exactly opposes your statement: mcrypt_generic_end (PHP 4 = 4.0.2) mcrypt_generic_end -- This function terminates encryption Description bool mcrypt_generic_end ( resource td) Warning This function is deprecated, use mcrypt_generic_deinit() instead. It can cause crashes when used with mcrypt_module_close() due to multiple buffer frees. So maybe something else is causing Vincent's problem to decrypt.

You could make some script to retrieve the hex values of the image byte by
byte, then create a source file like
$imgdata = '\xff\x19\x00\x12 etc...;
Then when you're about to send the image simply transmit the correct
header() and echo out the data.
This little sample works just perfectly:
// use one of your files here, of course...
$file = 'images/dart.gif';
$hf = fopen($file, 'r') or die(Can't open $file for reading);
$bin = fread($hf, filesize($file));
fclose($hf);
$asc = '$img_data = ';
for ($i = 0, $len = strlen($bin); $i $len; ++$i) {
if ($i !($i % 16))
$asc .= \ .\n\t\;
$asc .= '\\x' . bin2hex(substr($bin, $i, 1));
}
$asc .= ';';
// $asc now contains the hex-coded binary file.
// Example (a real gif - try it)
$img_data =
\x47\x49\x46\x38\x39\x61\x20\x00\x20\x00\xa2\xff\x00\x00\x00\x00 .

echo $img_data; // send it
exit;// and voila
Note that reading the file is only needed once as a tool to create the
ascii version of the binary file.

BullsEye indeed! After adjusting for win32 (added 'b' to fopen's) this script
is a little gem. You really saved me quite some headaches. Thanks!

[PHP] contact list re-ordering (php/mySQL CMS design)
Dear guru's, Hit a problem while developing a CMS with php/mySQL. Part of this is a contact list and this works ok (add/edit/delete with insert/update/delete queries). Now the client has requested a new feature: ability to change the order in which the contacts are being presented in the public part of this CMS (don't ask me why). I've added a field 'show_pos' to the contacts table and am able to change its value when I edit an existing record or add a new one. What I can't wrap my head around at the moment is how one deals with updating 'show_pos' for the OTHER records (while editing/deleting present record (WHERE id='$id')? Could anyone give me some pointers as to how this could be done in php and/or SQL (preferable). I sure hope anyone understands what I mean ...

[PHP] Euro symbol [textarea/e-mail]
Hi PHP guru's, I've got a working script that picks up a msg from a textarea and (after validation etc.) mails out a plain text confirmation e-mail (using fsockopen). So far, so good. Only problem is when the textarea contains the Euro symbol, it is replaced in the plain mail (replaced by ¤). Does anyone have any hints on how to solve this? PS: I am aware of the $euro = htmlentities(¤,ENT_QUOTES,iso-8859-15); way of outputting the Euro symbol in HTML...
