Problem $3$: ASCII Art

Build a PHP page that outputs a rounded rectangle with a bullseyethat looks like this:

The symbols to use are:

The upper left and lower right corners use this slash:$/$

The upper right and lower left corners use this slash: $1$

The upper edge uses dashes: $-$

The lower edge uses underscores:

The right and left edges uses a pipe: $|||$

The middle uses a plus sign: $+$

The number of rows and columns should come from a single variable $($it will be a square$).$

No need to make it a form, just declare the variable in your PHP file. To make your life

easier, you only need to make it work if the number of rows and columns are an odd

number and greater than or equal to $5.$ No need to validate the number, its ok if it fails with

an even number. For example, a $55$ square would look like this:

Ideally you can commit this in a new repository in your GitHub but it is not required.
