Searching An Array - Search The Second One With The First Ones Array Keys?
I've been banging my head against this one for awhile. One array has numbers like awz001 for keys and the count of how many times they appear as values. There's about 300 key, value pairs in this array. So Array = ([awz001] => 7, etc...) and the other array is a multi-dimensional Array ( [0] => Array ( [number] => awz001 [0] => awz001 [Section] => Section one [1] => Section one ) Is there away to search the second one with the first ones array keys? Would you do it with two loops? First through the multi then the single?

Using Max() On Array Keys
i am using an array to store contact data within a session. it looks like this: $_SESSION['contact'][$key][<content>] $key counts the set of records, so i have $_SESSION['contact'][Ɔ'] $_SESSION['contact'][Ƈ'] $_SESSION['contact'][ƈ'] and so forth. [<content>] stands for the fields containing the actual set of data, which are stored within the [$key]-arrays. at one point i need to find out what the highest value of $key is. running max($_SESSION['contact']) simply leaves me with "Array()" as the result. what i am doing wrong, and how do i correct it?

Automatic Array Keys
My array keys are behaving strangely. In the manual it says calling an array like $array[] = "something" should make the value be put into the next available integer key available. However, my values are being placed with whole sets of blank keys inbetween. Here's what part of the print_r() of the array returns: Code:

Print Out Array Keys Only
Hi, there are lots of examples that show you how to print array values given a key. Do you know how to print keys for a given array. example $myArray = array('a'=>1, 'b'=>2, 'c'=>3, 'd'=>4); How do you print 'a', 'b', 'c','d' only without using any loops?

Reverse Array Keys
See the following example: [4] => 'value1' [0] => 'value2' [1] => 'value3' [3] => 'value4' [2] => 'value5' should become [0] => 'value1' [4] => 'value2' [3] => 'value3' [1] => 'value4' [2] => 'value5' As you can see, the keys have been reversed such that the lowest key value is now the highest.

How To Get Two Keys From Array Loop?
I have an array that stores ids, each of which is unique. Is there a way to run a for loop and get two keys at a time instead of only one? Example $id = array(1, 2, 3, 4, 5, 6); for loop.... echo key 1 echo key 2 next loop echo key 3 echo key 4 and so on.... Each key must not appear twice so once a key is displayed, it will be removed from any further loops. I need it to display two keys at a time because I will be pairing them up for the next part of the script.

Recreate The Numeric Array Keys 0
Is there a php function that will recreate the numeric array keys 0 to what ever is in the array or should I just render a new temp array with a while or foreach loop? I'm trying to do some array manipulation and not having the array keys in sequence does not work. Partly I'm trying to create an SQL query with ID='value' OR with a loop but cannot have an OR after the last entry, so I'm ctrying to count() the array and use the condition of 'count() - $key > 1' to insert the OR so that when the last on is reach it does not because it is = to 1. When the array not in sequence the that last key and count value will not work together properly.

Getting Deep Array Value Without Knowing Keys?
I've racked my brain for the last few hours trying to figure this one out. I have an array of language strings such as : $lang = array(); $lang['en']['prompt']['hello'] = 'hello' $lang['en']['prompt']['bye'] = 'goodbye' $lang['en']['number']['first'] = Ƈst' This is being used by an ajax routine, so I don't know which string will be requested at runtime. So, I've got $lang and a request ('en_prompt_hello'), and tried a few things such as: $request = explode ($request); $found_string = array_intersect_assoc ($lang, $request); to no avail. Short of having to do a complicated recursion searching at every available depth, is there an easy way to do this?

Wild Cards For Array Keys?
I have a pretty complex array that stores information for fields. The following array element is a boolean: $_POST['fields'][$i]['listing'] Where $i starts a 1 and can go on for however long the user inputs into the form. So lets say the users input 20 fields. How exactly would I count how many of those array elements are equal to 1, without doing a loop? Is it possible to insert a wild card in place of $i? I already have a lot of nesetd loops and the last thing I want to do is add another one.

Argument To Keys() Should Be An Array In Main.inc On Line 152
I am getting the following errors: Warning: Argument to keys() should be an array in main.inc on line 152 Warning: Non array argument supplied for foreach() in main.inc on line 152 I've developed the site on my linux box at home using PHP 4.0.3pl1. It works great, but when I upload it to my hosting service I get the above messages. I've tried all the different ways to go through an associative array. I've tried doing an implode(array_keys($arr), ',') then split on ','. It keeps coming back to the fact that it doesn't recognize the array I declare right before it is an array. The hosting service runs a BSD Bosx and uses PHP 4.0b2. I'm wondering if this was a problem with the second beta release or if it is something screwy between platforms.

Calling Array Keys With Embedded Variables
I'm in the middle of modifying a script and I've come across a problem. I have a form that gets repeated x number of times and each field in the form gets the name $item_number_ . $business_item_index ._(the specific field name). These varaibles get reposted to the same page as $_POST variables, so that the forms save the users settings. What I'm trying to do is parse through those fields that the user did not set, and if they are null, to unset them and decrement the counter($business_item_index) so that one less form gets written to the screen the next time the user submits.

UNSET'ing Multidim Array Elements And Reseting Keys
I have a script that calls code plugins that return associative arrays: $aData[0]... $aData[1]... $aData[2]... $aData[3]... $aData[4]... $aData[5]... $aData[6]... $aData[7]... I would like to run a search on the array data and UNSET the array rows that do not meet my criteria (this part I know how to do). This means I end up with: $aData[0]... $aData[1]... $aData[3]... $aData[5]... Once this is done, I'd like to reset the first level key names to be consecutive like this (this is where I need help; I'm hoping for a existing builtin function but so far have not been able to find one): $aData[0]... $aData[1]... $aData[2]... $aData[3]... I'll find out soon enough once this is working but does anyone know is UNSET eats up alot of time? on large arrays?

Primary Keys Vs Index Keys

Is there any significant speed/memory differences from accessing records via a VARCHAR index key as opposed to an INT primary key?

Changing Object Data In An Array Of Objects
In this sample script I create an array of objects. Print out their data with print_r().Update their data with a sub called v_set(). Print out data showing the chnages using print_r(). I push the altered objects into a new array and print them out again, still see the updated data. Then I iterate over the original array again with print_r and the objects lose the updates and have their original data. <? for ($i = 0; $i < 1; $i++) { $listingObj = new Listing; $listings[] = $listingObj; } foreach ($listings as $aListing) { echo "<h3>THIS IS IN SCRIPT IN ORIG ARRAY BEFORE VARS SET</h3>"; f_array($aListing); } foreach ($listings as $aListing) { $aListing->v_set( array( 'name' => 'Jane', 'address' => Ïã Ohce Ln.' ) ); // HERE IS BUG: WHY DO I NEED TO PUT IN NEW ARRAY? echo "<h3>THIS IS IN SCRIPT IN ORIG ARRAY AFTER VARS SET</h3>"; f_array($aListing); $newArray[] = $aListing; } foreach ($newArray as $aListing) { echo "<h3>THIS IS IN NEW ARRAY</h3>"; f_array($aListing); } foreach ($listings as $aListing) { echo "<h3>THIS IS IN ORIG ARRAY, APPARENTLY NOT ALTERED/UPDATED?</h3>"; f_array($aListing); } class Listing { var $changedVals = array(); var $name = 'Dick' var $address = ì« Echo Ln.' function v_set($data){ foreach ($data as $key => $value) { $this->$key = $value; $this->changedVals[] = $key; } } } function f_array($array) { echo '<pre>' print_r($array); echo '</pre>' } ?>

Keys
I've been coding with PHP for quite some time now, but still I have never had to use keys in my databases, so I've never learned how too.. Now I realize that it is more efficient to call users in a db with a 'uid' field instead of their user name. -How do I go about setting this up? -How do I enter a new row into my db - do I need to set a value for the 'uid' field or will it increment itself? (that seems to be the point anyways)? -Any helpful articles / posts you can point me to regarding this?

Foreign Keys
Normally, my tables have a primary key, and usually it's an auto-incrementing integer - unless, occasionally, it's an alpha string like a UserName or something. then, I may have a "dependent" table with a foreign key field which references the primary key of the "parent" table. Now, I know it's possible to have a primary key made up of multiple columns - I call that a compound primary key myself. I do that occasionally. However, is it possible to have a "compound foreign key" ? I.e. a foreign key of two columns, which refers to the two columns for the primary key? I realize you can do that by just creating the tables that way, of course, but can you set referential integrity on that? And how would you do that?

PHP & MySQ + Unique Keys
I'm trying to write a system thats used for about 50 clients that uses html forms and php to log details. The problem is that when a client loads the form page it's given a value which is the last record in a table +1 (i.e. so its the next record). The problem with that is that a client could sit on that page for 20 mins (or whatever length of time) and a different client could use that record number and there what be an error "duplicate key....". I could use an MySQL UPDATE to lock the record when its issued to each client and maybe use a timestamp and check if the timestamp is over 10 mins and delete any records that are over 10mins but there is the possibility of redundant data (or really useless data, a unique record and a timestamp) in the table sitting there for 10mins at a time. Is there an easy way of 'gauranteeing' a client a unique key? So you don't have to lock the record when the page loads (this also means that when you refresh the page that the unique key is incremented as you locked the last record and didn't put anything into the table, so the refreshed page is issued the next key +1 again).
