I made a mistake on my previous note. I used rtrim instead of just trim to take off the curly brackets. Here is my note again - or please change the RTRIM to just TRIM in my previous note. Thanks! :-) Kristof_Polleunis at yahoo dot com has an excellent function for obtaining a GUID but I believe it can be improved by checking for whether or not to remove the curly braces so the programmer who uses it doesn't have to do this. Here is the improved function: <?php # # Taken from the PHP documentation website. # # Kristof_Polleunis at yahoo dot com # # A guid function that works in all php versions: # MEM 3/30/2015 : Modified the function to allow someone # to specify whether or not they want the curly # braces on the GUID. # function guid( $opt = true ){ // Set to true/false as your default way to do this. if( function_exists('com_create_guid') ){ if( $opt ){ return com_create_guid(); } else { return trim( com_create_guid(), '{}' ); } } else { mt_srand( (double)microtime() * 10000 ); // optional for php 4.2.0 and up. $charid = strtoupper( md5(uniqid(rand(), true)) ); $hyphen = chr( 45 ); // "-" $left_curly = $opt ? chr(123) : ""; // "{" $right_curly = $opt ? chr(125) : ""; // "}" $uuid = $left_curly . substr( $charid, 0, 8 ) . $hyphen . substr( $charid, 8, 4 ) . $hyphen . substr( $charid, 12, 4 ) . $hyphen . substr( $charid, 16, 4 ) . $hyphen . substr( $charid, 20, 12 ) . $right_curly; return $uuid; } } ?> As the comments say - set the incoming option ($opt) to either TRUE or FALSE depending upon whether you want the curly braces to always show up or not. If you need to obtain a GUID in the other way - all you have to do is to send the opposite value to the function. ---- Server IP: 72.52.91.14 Probable Submitter: 66.196.239.162 ---- Manual Page -- http://php.net/manual/en/function.com-create-guid.php Edit -- https://master.php.net/note/edit/116983 Del: integrated -- https://master.php.net/note/delete/116983/integrated Del: useless -- https://master.php.net/note/delete/116983/useless Del: bad code -- https://master.php.net/note/delete/116983/bad+code Del: spam -- https://master.php.net/note/delete/116983/spam Del: non-english -- https://master.php.net/note/delete/116983/non-english Del: in docs -- https://master.php.net/note/delete/116983/in+docs Del: other reasons-- https://master.php.net/note/delete/116983 Reject -- https://master.php.net/note/reject/116983 Search -- https://master.php.net/manage/user-notes.php
