title: php script in bash loop
body: <p>I'm a beginner bash coder, and have a PHP script; in each run it returns 0 or 1 and I need a bash script that runs this PHP script until it returns 1. </p>
  
  <p>PHP script:</p>
  
  <pre><code>/* sample code */
  echo $number;
  </code></pre>
  
  <p>Bash script:</p>
  
  <pre><code>#!/bin/bash    
  output=`php /var/www/site/script.php`
  while [$output == 1]
  do
  output=`php /var/www/site/script.php`
  done
  </code></pre>
  
  <p>The PHP script is working, but the bash script doesn't work</p>
  
  <p>Bash returns</p>
  
  <pre><code>$ bash /root/loop.sh
  /root/loop.sh: line 6: syntax error near unexpected token `done'
  </code></pre>
