Declaring BASH. Array of strings in a a script

I'm writing a small script to test my regex understanding of comparison operator "=~". I thought that my syntax was alright but I keep getting:

3: Syntax error: "(" unexpected

this is my small script link to this syntax error :

#!/bin/bash

inputsArr=("ab" "67" "7b7" "g" "67777" "07x7g7" "77777" "7777" "")

for input in ${inputsArr[@]}; do
  if [[ "$1" =~ "$input" ]]; then
    echo "$?"
fi
done

I try to compare in a loop with an array some "strings" against my arg1 or "$1"

I just reach my goal with this !

#!/bin/bash

inputsArr=("ab" "67" "7b7" "g" "67777" "07x7g7" "77777" "7777" "")

for input in ${inputsArr[@]}; do [[ "$input" =~ $1 ]]; echo "$?" ; done

I would like to say thanks you to every person that give me some tips on this basic BASH script problem. Without you I would certainly not reach my goal by my own way and it is beautiful to see this cooperation in action.

The code works in bash, you just need to run it in the right shell, you can do the following:

  bash ./script.sh g

Also type ps -p $$ (not echo $SHELL) to see what shell you are currently in:

Examples:

# ps -p $$
    PID TTY          TIME CMD
  25583 pts/0    00:00:00 sh
# exit
# ps -p $$
    PID TTY          TIME CMD
  22538 pts/0    00:00:00 bash
