eregi

[SPYDERIX]

I have been out of the programming game for a while now and I've tried to implement an old script I created but now have an error saying the eregi() function was removed and it throws an error. How would I re-write this now:

if (empty ($_POST["var"]) || !eregi ("^[0-9]+$", $_POST["var"]))
[indent]{
// validation failed
}[/indent]

I tried this with preg_match but it's no bueno. Need to check if the string is a number basically:

$str = "7856";
$pattern = "^[0-9]+$";

if (preg_match($pattern, $str))
	{
    echo 'val passed';
    }
else
	{
    echo 'val failed - string is not a number';
    }

Hi

PCRE must have delimiters. The most frequent ones used to be [tt]/[/tt] .. [tt]/[/tt] :

[b]if[/b] [teal]([/teal][b]empty[/b] [teal]([/teal][navy]$_POST[/navy][teal][[/teal][i][green]"var"[/green][/i][teal]]) || ![/teal][COLOR=orange]preg_match[/color][teal]([/teal][i][green]'[highlight]/[/highlight]^[0-9]+$[highlight]/[/highlight]'[/green][/i][teal],[/teal] [navy]$_POST[/navy][teal][[/teal][i][green]"var"[/green][/i][teal]]))[/teal]
[teal]{[/teal]
    [gray]// validation failed[/gray]
[teal]}[/teal]

( Note that [tt]$[/tt] and other characters have special meaning when used in double quoted ( [tt]"[/tt] .. [tt]"[/tt] ) strings, so unless you need variable expansion, is better to use single quoted ( [tt]'[/tt] .. [tt]'[/tt] ) strings for regular expressions. )

Ok cool. Thanks. I honestly have never fully grasped REGEX. It seems complicated to me
