PHP - Searching A Array While Selecting From Mysql

Currently my code picks a random number between 1-6 then extracts that many (random) entries from a list in my database.

My current code displays the whole array, how can I chop the array into 6 bits so I can output the data separately (up to 6 list items)?

$con = mysql_connect("x","x","x");
if (!$con)
   {
   die('Could not connect: ' . mysql_error());
   }

mysql_select_db("x", $con);

$ran_x = rand(1,6);
$appearance_query = "SELECT * FROM  `x` ORDER BY RAND( ) LIMIT $ran_x";
$get_x = mysql_query($x_query);

echo 'x(s): ';
echo '<br />';
echo "<ul style='list-style:none;'>";

while($row = mysql_fetch_array($get_x))
   {
echo "<li>" . $row['x'] . "</li>";
   }

echo "</ul>";
echo "<br />";

mysql_close($con);

Any help would be greatly appreciated,

Thanks,

Hi guys,

essentially, I have very limited knowledge with mysql and have hit a brick wall.

The row that I am trying to select is the following:


Now, I am trying to use the following script to achieve that:

Quote

$query = "SELECT meta_value FROM wp_usermeta WHERE user_id='$id' & meta_key='simple_local_avatar'";


The $id is being passed as 1 from a cookie, and I know for sure that thats working properly, but I cant figure out the coding to select it correctly.

I need the script to search for the ID of the user & then user the simple_user_avatar to find the right entry.

Please someone cast your knowledge and help me out!

Oh, little adendum.

All that happens when the script runs is that the first row of the table is called out, which is:

Greetings all.

I am building a website which will have a popup box.
When a link is clicked on, the proper data will show in the box.
I just need to know how I can detect which link was clicked.

e.g.
<a href="#">link one</a>
<a href="#">link two</a>


$a[1]="item1 | item2 | item3"
$a[2]="item4 | item5 | item6"

list($one, $two, $three)=explode("|",$a )

Where x is dependent on the link clicked.

All the sites I have seen so far speak of basic array structures and how to set them up.
If it makes any difference, the links are inside an unordered list setup.

Thanks for any help.

Hi there,

I'm working on PHP webform and I have a variable called $weightInfo which has the value 5000|6000

Now I have a list of Arrays and I would like to see if our variable value (i.e 5000|6000) is in that list of Array: Here is the ArrayList:

 $WeightArray = array('' => '',
    '0|100' => '100g or Less',
    '101|250' => '101g to 250g', 
    '251|500' => '251g to 500g',
    '501|1000' => '501g to 1kg',
    '1000|2000' => '1kg to 2kg',
    '2000|3000' => '2kg to 3kg',
    '3000|4000' => '3kg to 4kg',
    '4000|5000' => '4kg to 5kg',
    '5000|6000' => '5kg to 6kg',
    '6000|7000' => '6kg to 7kg',
    '7000|8000' => '7kg to 8kg', 
    '8000|9000' => '8kg to 9kg',  
    '9000|10000' => '9kg to 10kg',
    'customValues' => 'Custom Values'
    );

Now as we can see, in this ArrayList, there is that value 5000|6000.

How do we find this through code, do we need some kind of looping or how do we check it.

Kindly reply.

Thank you

I am including my test.php for other to run.

I have a very large array of concatenated hash values. I have another array that contains the first 8 hash values of the other array. I have a function to locate them in the larger array. Depending on their index value I then choose the index of the value before or behind them for adding to something else later. This 'computeWalk' method works for small arrays but for larger arrays I notice duplicates or errors with larger ones.

For example.

The first array returns:
Array ( => 1 [1] => 18 [2] => 18 [3] => 35 [4] => 33 [5] => 33 )
The values for i's to get each of these values are
I = 0
I = 19
I = 29
I = 34
I = 37
I = 39

Walking through the method by hand,
0%2 = 0
So the first element of the array will be 1. CORRECT.
19%2 = 1
So the next element will be 18. CORRECT.
29%2 = 1
The next element should be 28. It returns 18.
34%2 = 0
The next element will be 35. Correct.
37%2 = 1
The next element should be 36. It returns 33.
39%2 = 1
The next element should be 38. It returns 33.

I am not sure why it's doing the above.
I also tried array_search and it computed it the same way.

Would appreciate any help.
