    <p>I have a question about strings in Javascript and PHP. Currently, I have a client side script (in Javascript obviously) that gets the string from an html form and prints it out. As of right now, I just copy it into the php script (on the server obviously). Later, when I know the scripts work I am going to have the javascript send it to the server automatically but right now I want to make sure that the code I have written is correct. When I do the copying of the string, I get two different sha1 hashes. I suspect that there are different null terminators or something quirky like that because when I print them out, they are are same amount of characters and match exactly (at least to the naked eye). I was wondering if anyone knew how to fix this to make it the same hash. Thanks. The Javascript code that deals with the msg. The javascript gets the msg from a html document. The javascript sha1 hash is from <a href="http://crypto-js.googlecode.com/files/2.5.3-crypto-sha1.js" rel="nofollow">http://crypto-js.googlecode.com/files/2.5.3-crypto-sha1.js</a></p> <pre><code>var msg=document.input.msg.value; digert = digest + Crypto.SHA1(msg); digestBytes = Crypto.SHA1(msg, {asBytes: true}); digestString = Crypto.SHA1(msg, {asString: true}); </code></pre> <p>The code php code that deals with the msg. It gets the message from a html form that posts it to a php script.</p> <pre><code>//finds the starting point of the message $start_MSG = stripos($_POST["message"], ' ')+1; //stores the message in a global variable $GLOBALS['msg'] = substr($_POST["message"], $start_MSG); $temp_hash2 = sha1($_POST["message"], false); </code></pre>

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.
