    <p>I have a simple calculator script for making calculations of facebook insights.</p> <p>There is a function in my script called fb_growth where I pass two arguments in: one for the current month's data ($moc) and one for the previous month's data ($mop) and I am trying to find the growth percentage (positive or negative) between the 2. Here is my function script:</p> <pre><code>//Growth Calculator Function function fb_growth($moc, $mop) { if($moc&gt;=$mop) { $grp = ($moc/$mop); $grf = ($grp - 1); return $grf; } else if($moc&lt;$mop) { $grp = ($mop/$moc); $grf = (1 - $grp); return $grf; } } </code></pre> <p>The values I enter in are coming from a form that the user fills out. In this particular case, the numbers passed in are <code>fb_growth($fbfi1, $fbfi2);</code> where $fbfi1 equals the string '1719223' and $fbfi2 equals the string '1859867'. In this case, $moc is less than $mop, so 1719223 gets divided by 1859867, which should return 1.08180672315, but instead it returns 1, which then gets subtracted by 1 to get 0. What I want to end up with is '-.08180672315', which would be my growth percentage, but I cannot get it to give me this outcome. If I <code>echo ("1859867"/ "1719223");</code> then I get 1.08180672315, but when the strings are held in the variables and I <code>echo ("$fbfi2" / "$fbfi1");</code> then I get 1. </p> <p>I tried settype() to a double and an int for $grf and for both $fbfi1 &amp; 2 and same result. If I set $grf as a global and echo gettype(), it will give me the double or the int, but I still get the same value: 0. Is there something I can adjust in my php settings for this, or is there something wrong with my setup? I can't find any documentation. Help is MUCH appreciated, thank you!!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
