If it's in an array

[juanc]

Hi

Is there a way of determining whether or not a value or values are present in an array.

Is there something nice and easy as with php's

if(in_array($SomeValue,$myArray)){
echo "The value is here";
}
else{
echo "The value is not here";
}

Thanks........and hope no one minds me writing a bit of php in this the asp section of the forum ;-)

There is no function lik ePHP
you have to write ur own and no shortcut, okay you have to find in the array byself function

Not true. You can use the isarray function:

example:

<% If IsArray(arrvariable) Then %>
   array exists
<%Else%>
   array doesn't exist
<%End if%>

Hi thanks for these posts!

I don't know if the IsArray function actually does what I need though.......

basically I need to check whether one specific value is actually in the array as opposed to whether or not the variable itself is an array or not.........

Any other ideas

thanks very much

As far as I know, there is no way to see if a string is in an array with ASP.

You'd need to either loop through the array searching for the string, or join the array and use the InStr function to look for a string within a string, something like:

Function InArray(arr, search)
	If InStr(1, "^^" & Join(arr, "^^") & "^^", "^^" & search & "^^") > 0 Then
		InArray = True
	Else
		InArray = False
	End If
End Function
