How do I convert an item from an array into a string variable

I'm trying to get a string array containing the selected objects ( $objectsArray[ ] ), and then I would like to only get the first item from that array and put it into a regular string variable ( $onlyFirstObject )

string $objectsArray[] = `ls -selection`;
string $onlyFirstObject = $curvesArray[0];

This doesn't work. What's the correct way to get only the first item in a string array, and store it in a string variable?

You have a small typo in the script. Set $onlyFirstObject to $objectsArray[0].

The first element in an array is always at position zero.

Code:

string $mySelection[] = `ls -sl`;
string $firstObj = $mySelection[0]

$mySelection[0] is already a string variable, just not as elegant as $firstObj

Just a nit-pick, but you should check if the length of the array is greater than zero before you choose the first element. user added image
