why javascript return another thing and php another one?

To fix this issue In your javascript code, when you do MD5 and SHA1 it returns an object that has the actual code, instead of an string with the hexadecimal representation. This means that the following operations are doing the hash over the numeric value instead of the string.
To fix it do a convertion to string in each step:
code :
<div id="messages"></div>
<script type="text/javascript" src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/sha1.js"></script>
<script type="text/javascript" src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/md5.js"></script>
<script type="text/javascript">
function md5(string)
{
return CryptoJS.MD5(string);
}
function sha1(string)
{
return CryptoJS.SHA1(string);
}
function encode(string)
{
var number = string;
var hash = md5(number);
var hash = sha1('' + hash); // <--- converting to string
var hash = md5('' + hash);
var hash = md5('' + hash);
var hash = sha1('' + hash);
var hash = sha1('' + hash);
var hash = md5('' + hash);
var hash = sha1('' + hash);
return hash;
}
var text = '8793';
document.getElementById("messages").innerHTML = encode('8793');
</script>

To fix the issue you can do Static Objects / Object Literals
Static objects, or object literals, don't require instantiation with the new operator and also behave like singletons. Consider the following example:
code :
var staticObject1 = {
 a: 123,
 b: 456
};
var staticObject2 = staticObject1;
console.log(staticObject1, staticObject2);
staticObject2.b = "hats";
console.log(staticObject1, staticObject2);
Object a=123 b=456  Object a=123 b=456
Object a=123 b=hats Object a=123 b=hats
var staticObject3 = dojo.clone(staticObject1); // See the doc in the link above
staticObject1.a = "pants";
console.log(staticObject1, staticObject2, staticObject3);
Object a=pants b=hats Object a=pants b=hats Object a=123 b=hats
var SomeObject = function() {
    var privateMember = "I am a private member";
    this.publicMember = "I am a public member";

    this.publicMethod = function() {
        console.log(privateMember, this.publicMember);
    };
};

var o = new SomeObject();
console.log(typeof o.privateMember, typeof o.publicMember);
o.publicMethod();
undefined string
I am a private member I am a public member
var SomeObject = function() {
    var privateMember = "I am a private member";
    var privateMethod = function() {
        console.log(this.publicMember);
    };

    this.publicMember = "I am a public member";
    this.publicMethod = function() {
        console.log(privateMember, this.publicMember);
    };
    this.privateMethodWrapper = function() {
        privateMethod.call(this);
    }
};

var o = new SomeObject();
console.log(typeof o.privateMethod, typeof o.publicMethod, typeof o.privateMethodWrapper);
o.privateMethodWrapper();
undefined function function
I am a public member
var SomeObject = function() {
    var self          = this;
    var privateMember = "I am a private member";
    var privateMethod = function() {
        console.log(self.publicMember);
    };

    this.publicMember = "I am a public member";
    this.publicMethod = function() {
        console.log(privateMember, this.publicMember);
    };
    this.privateMethodWrapper = function() {
        privateMethod();
    }
};

var o = new SomeObject();
console.log(typeof o.privateMethod, typeof o.publicMethod, typeof o.privateMethodWrapper);
o.privateMethodWrapper();
undefined function function
I am a public member

I hope this helps . I'm building a tagging system and I need to retrieve similar tags, so when a user would punch in "some thing" or "somé thing" or "söme thing" or "some¤thing" etc he would get all the matching rows in the table. , Yes, the convert :-
code :
mysql> select convert( "söme thing" using utf8) = 
convert( "some thing" using utf8);
+------------------------------------------------------------------------+
| convert( "söme thing" using utf8) = convert( "some thing" using utf8)  |
+------------------------------------------------------------------------+
|                                                                      1 |

should help you out Your code is wrong.
It will show suppliers that supply project 1 provided that they also supply at least one other project. You want to hide such suppliers. It will hide suppliers that do not supply any projects. You want to show such suppliers. It will repeat the suppliers' names for each entry from the Supply table. You want a list of names without repetitions.

hop of those help? The server is responsible for reporting the allowed origins. The web browser is responsible for enforcing that requests are only sent from allowed domains.
CORS is applied to requests when an Origin header is included in the request. This includes requests made from JavaScript and POST requests. It's not applied all resources. The origin is the protocol, host and port that is making the request. Requests made by JavaScript use the origin that loaded the JavaScript, not the origin that it was loaded from.
