get statement that retrieves only 4 characters from the right

[johnjohn2]

Does something like this exist to grab only the last 4 characters of a parameter?

right(($_GET['col33']),4)


Where the number "123456789" would equal "6789"

sub_str($_GET['col33'], -1, 4);

wrong...

sub_str($_GET['col33'], -1, 4); 

right...

substr($_GET["col33"], -4); 

cheers

[Daimaju]

wrong

substr($_GET['col33'], -4); 

i should test my code when i'm a little bit tipsy

[johnjohn2]

I tried it out but I'm getting this error:
Parse error: parse error, unexpected T_STRING, expecting T_VARIABLE or '$' in c:\inetpub\wwwroot\test2\411.php on line 36

I don't see any problem with the code. Is there one? Line 36 is the first instance of the "substr" entry. Here's what surrounds line 36:

$startRow_Recordset2 = $pageNum_Recordset2 * $maxRows_Recordset2;
$a1__Recordset2 = '-1';
if (isset(substr($_GET['col19'], -4))) {
$a1__Recordset2 = substr($_GET['col19'], -4);

[Daimaju]

if (isset(substr($_GET['col19'], -4))) { 

substr() returns a string, and isset() expects a $variable.

so if you wan't to check that $_GET['col19'] is set and at least 4 chars long use

if(isset($_GET['col19'] && strlen($_GET['col19']) > 3)
{
   $a1__Recordset2 = substr($_GET['col19'], -4);
}

?

$startRow_Recordset2 = $pageNum_Recordset2 * $maxRows_Recordset2;
$a1__Recordset2 = '-1'; # why that here???
if(isset(substr($_GET['col19'], -4))) { 
$a1__Recordset2 = substr($_GET['col19'], -4); # and then here again??? 

what is that???

maybe this will help...

if(!empty($_GET["col19"])) {
$a1__Recordset2 = substr($_GET['col19'], -4); 
}

May be this:

if(!empty($_GET["col19"],-4))
{
$a1__Recordset2 = substr($_GET['col19'], -4);
}

[reminder]

how can be if(!empty($_GET["bla"], -4)) ?

hth

if(strlen($_GET["col19"]) > 4) {
$a1__Recordset2 = substr($_GET['col19'], -4);
} 

cheers

This bit of code is from dreamweaver mx 2004. I've tested out:
<?php echo substr($_GET['col19'], -4); ?> on the screen and it gives the correct results. But when I put in dreamweaver's recordset builder and put in :
substr($_GET['col19'], -4)
as a "runtime" value in the variables box, this is where it fails.

May I have the coding ur using in Dreamweaver and in the PHP file.
