<div>
I have the following but I don't think it is correct.<br />
It is always echoing &quot;HELLO&quot;<br />

<pre><code id="code-20-41163404-1">$wave = $row['wavelength'];
   			$wave = explode(', ', $wave);
   			echo'&lt;br /&gt;'.$wave[0].'&lt;br /&gt;'.$wave[1].'&lt;br /&gt;';

   			$a = false;
   			$b = false; 

   			if($wave[0] &lt;= $wave_max) $a = true; 
   			if($wave[1] &gt;= $wave_min) $b = true; 
   			
   			if($a &amp;&amp; $b) $wavelength = true;
   			
   			if($wavelength) {
   				echo '&lt;h1&gt;HELLO&lt;/h1&gt;';
   			}		</code></pre>

I have the following but I don't think it is correct.
It is always echoing "HELLO"


$wave = $row['wavelength'];
   			$wave = explode(', ', $wave);
   			echo'<br />'.$wave[0].'<br />'.$wave[1].'<br />';

   			$a = false;
   			$b = false; 

   			if($wave[0] <= $wave_max) $a = true;

PHP Variables Great Than Less Than

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.
