There is a "===" operator in sqlparser.lib.php3.

I just never got around to trying your solution, since I don't have access to a PHP3 installation.

I don't remember what was my solution. But maybe the person who has the problem could try the solution if you can feed it in the thread:

Shouldn't it be possible to replace

($a === $b)

by the following expression?

($a == $b && gettype($a) == gettype($b))

gettype( ) works on variables, but the case we have is: if(strpos($whatWeWant, $typeSeperator) === FALSE) {

I don't know if it works on expressions and constants.

Anyway, looking at the code, we usually workaround this strpos problem with the "append a blank" trick:

if (strpos(' ' . $goto, 'tbl_properties') == 1) {

Of course, it does. gettype() checks the type of the expression. A variable is also an expression, just like a function call, a mathmatic operation or whatever. I'm taking your example and using my workaround:

if (strpos($whatWeWant, $typeSeperator) == FALSE && gettype(strpos($whatWeWant, $typeSeperator)) == gettype(FALSE)) {

Of course, we can make this a bit shorter:

$tmp = strpos($whatWeWant, $typeSeperator); if (!$tmp && gettype($tmp) == 'boolean') {

But our usual workaround for the strpos problem is this one:

if (!strpos(' ' . $whatWeWant, $typeSeperator)) {

Your code above appears incorrect to me because we want to have the case that the needle string does not appear in the haystack string, don't we? So 1 is wrong, it has to be 0 or FALSE (doesn't matter since 0 == FALSE :o) ).

Ok Alexander. I have merged this, and usually we should use \xff instead of a blank because chances are lower that we find a real \xff:

if(!strpos("\xff" . $whatWeWant, $typeSeperator)) {
