should there record of php sent mail (via our hosts mail() function) anywhere? our web developer made oversight , enquiries sent via our host's (godaddy.com) mailer relay last 2 months rejected our local mail server. naturally, our server doesn't keep rejected emails. i have spoken godaddy.com , claim there no record, i'm not particularly confident answer. is there can do? enquiry form fixed (used mandrill), that's not issue. no, mails gone now. rejected mails mail server tried send go mail admin account of sending server bounce - however, account might not set or failing or rejecting mail, mail server rid of these undeliverable mails double-bounced deleting them queue. you might idea of tried mail if able hand onto mail server logfile, assuming in hands of hosting provider, chances low: 1. these logs give idea of mail addresses involved, no content. 2. log files deleted because they'd serve no regular purpose.

i have url looks like: url.com/picture.php?id=51 how go converting url to: picture.php/some-text-goes-here/51 i think wordpress same. how go making friendly urls in php? you can 2 ways: the .htaccess route mod_rewrite add file called .htaccess in root folder, , add this: rewriteengine on rewriterule ^/?some-text-goes-here/([0-9]+)$ /picture.php?id=$1 this tell apache enable mod_rewrite folder, , if gets asked url matching regular expression rewrites internally want, without end user seeing it. easy, inflexible, if need more power: the php route put following in .htaccess instead: fallbackresource index.php this tell run index.php files cannot find in site. in there can example: $path = ltrim($_server['request_uri'], '/'); // trim leading slash(es) $elements = explode('/', $path); // split path on slashes if(empty($elements[0])) { // no path elements means home showhomepage();...

i building program copies directories each other, can work hard coded. i want directory input user via command line argument. i have used char srcpath[] = argv[1]; however when hard code char srcpath[] = "home/user/desktop/cat"; works fine. but doesn't work, can explain why / suggest way this? , there special way directories have input when used in cli? argv[] array of char pointers, therefore when use argv[1] obtaining second item in array char pointer. james suggested if want store value of argv[1] memory address have use identical type in case char * . if need save directory path sort of processing or manipulation, need store command line argument inside char array. char srcpath[100]; int i; (i = 0; argv[1][i] != '\0'; i++) { srcpath[i] = argv[1][i]; } array names pointers using subscript [] dereferences it. same can said char arrays stored inside of argv[]
