mssql_guid_string

Converts a 16 byte binary GUID to a string (PHP 4 >= 4.0.7, PHP 5, PECL odbtp:1.1.1-1.1.4)
string mssql_guid_string ( string binary [, int short_format] )

Examples ( Source code ) » mssql_guid_string


<?php

$binary = '19555081977808608437941339997619274330352755554827939936';


var_dump(mssql_guid_string($binary));

var_dump(mssql_guid_string($binary, true));

?>



The above example will output:


string(36) "35353931-3035-3138-3937-373830383630"

string(32) "31393535353038313937373830383630"

Using MSSQL2000 and PHP4.3.1 and FreeTDS-0.61 (always compile it with --enable-msdblib --with-tdsver=7.0 for proper working) this function won't give you the strings what you can see in MS's Enterprise Manager for uniqueidentifiers! And the given strings also useless in SELECTs! To get the number what you can reuse in later SELECTs, use this: $q1 = mssql_query("SELECT cast(id as varchar(36)) FROM sales WHERE ..."); where in table 'sales' the column 'id' type is uniqueidentifier.

php3 to php4 note warning! php4 handles MSSQL GUID like binaries values and not like a string as php3 used to do. Even if you set in your php.ini : mssql.compatability_mode = On

in php5 on w2k server and apache works well: echo mssql_guid_string($RS['T_ID']); is same string as unique identifier in SQL manager (T_ID) selectet with a standard sql select clause. im using it in a form to select just this unique dataset to delete like this: echo <form name="Delete" action="'.$_SERVER['PHP_SELF'].'" method="post"> <input type="hidden" name="mode" value="del"/> <input type="hidden" name="T_ID" value="'.mssql_guid_string($RS['T_ID']).'"/> <input type="submit" value="DEL"/></form>'; there seems to be a matrix like this one running at least this function returns the same value: if you call it like makeuniqueid($RS['T_ID']) function makeuniqueid($hs) { if (strlen($hs) == 16) { $hexstring = bin2hex ($hs); return $sql_uniqueid=strtoupper(substr( $hexstring, 6,2).substr( $hexstring, 4,2).substr( $hexstring, 2,2).substr( $hexstring, 0,2).'-'.substr( $hexstring, 10,2).substr( $hexstring, 8,2) .'-'.substr( $hexstring, 14,2).substr( $hexstring, 12,2).'-'.substr( $hexstring, 16,4).'-'.substr( $hexstring, 20,12)); } else { $sql_uniqueid = "not valid"; return $sql_uniqueid; } }

Here is the function that will present the GUID as we commonly know it in PHP. I designed this function before noticing the one (slightly documented in here). It has been fully tested and works. function presentGUID($string) { $hex = ''; $len = strlen($string); $bytes = array(); for ($i = 0; $i < $len; $i++) { $bytes [$i] = strtoupper(str_pad(dechex(ord($string[$i])), 2, 0, STR_PAD_LEFT)); } $this->swapbyte ($bytes[0], $bytes[3]); $this->swapbyte ($bytes[1], $bytes[2]); $this->swapbyte ($bytes[4], $bytes[5]); $this->swapbyte ($bytes[6], $bytes[7]); $hex = "{"; for ($i = 0; $i < $len; $i++) { switch ($i) { case 4: case 6: case 8: case 10: $hex .= "-"; } $hex .= $bytes[$i]; } $hex .= "}"; return $hex; } function swapbyte(&$value1, &$value2) { $tmp = $value1; $value1 = $value2; $value2 = $tmp; }
