PHP - Adding Elements From One Multidimensional Array To Another
Suppose I have 2 arrays like the two below. I want to change each element of the first array. I want to add [‘person_id’] => 3 to each element and I want to add the [name] element from each element of the second array to each element of the first, with the [name] value corresponding. i.e. [name] from the first element in array 2 added to the first element of array one, [name] from the second element of array two added to the second element of array one, and[name] from the third element of array two added to the third element of array one. The element can be called "name" in each element of the first array. Thus the person_id would be the same in all elements of array one and the name element from array two would be added, changing for each element. It’s kind of a foreach in a foreach and I couldn’t figure out how to do it. array_walk might be useful as well though I couldn’t figure that our either. What’s happening here is that I am uploading three image files and want to insert the information about each file into corresponding file fields in a row determined by the person_id, extracting the image filenames from array 2. Thanks for help with this, —Kenoli

Similar TutorialsI have created a session array on one page and stored some values as $_SESSION['users'] = array( "id" => $row['id'], "fname" => $row['ufname'], "lname" => $row['ulname'] ); and then on another page I have some more values for the same session array "boss" => $row['bossid'], "tasks" => $row['tasks'], "timeframe" => $row['tframe'] I want to add these values into session array both keys and values. is there any way of doing this? Please help Hi, I'm trying to explode an array into a multidimensional array using <br /> tags as splitters but just can't get the syntax right! I can do lines of the array one by one, but not the whole lot at once. I'd really appreciate a quick example of an explode inside an array. $myarray looks something like this with print_r: ( [0] => [1] => some_html<br />some_html<br />some_html<br /> [2] => some_html<br />some_html<br />some_html<br /> [3] => some_html<br />some_html<br />some_html<br /> ) and I want to turn it into this: ( [0] => [1] => [0]some_html [1]some_html [2]some_html [2] => [0]some_html [1]some_html [2]some_html [3] => [0]some_html [1]some_html [2]some_html ) I've tried this $myarray = explode ("<br />", $myarray); but it doesn't work … It doesn't matter too much if there's are a few empty lines in the array from the final <br /> tags. Many thanks, as ever, for any help. I have the following array structu Code: [Select] [0] => Array ( [id] => Array ( [$t] => http://www.google.com/mate/ ) [updated] => Array ( [$t] => 2011-08-31T11:43:05.942Z ) [category] => Array ( [0] => Array ( [scheme] => http://schemas.google.com/g/ [term] => http://schemas.google.com/contact/ ) ) [title] => Array ( [type] => text [$t] => Name ) [link] => Array ( [0] => Array ( [rel] => http://schemas.google.com/contacts/2008/rel#edit-photo [type] => image/* [href] => https://www.google.com/mate/feeds/photos/media/ ) [1] => Array ( [rel] => self [type] => application/atom+xml [href] => https://www.google.com/mate/feeds/contacts ) [2] => Array ( [rel] => edit [type] => application/atom+xml [href] => https://www.google.com/mate/feeds/ ) ) [gd$email] => Array ( [0] => Array ( [rel] => http://schemas.google.com/g/2005#other [address] => email_address@gmail.com [primary] => true ) ) ) I am tried to display name and email address. I am using following method, can anyone tell me is there any better way? Thank u 4u help. NAME $name=( $emp_det[0]['title'][t]); $email =( $emp_det[0]['gdemail'][0][address]); I've been working on some code to: 1. Search a db for rows that have a particular "position" value 2. Search the same db for rows that have a particular "langs" value 3. Compare the two arrays resulting for 1 and 2 4. Create a multidimensional array $langsarray[langs][question id] if 3 is true. 5. For each langs array in $langsarray pick a random, non-duplicate value and add it to $qarray for a maximum of 12 elements (3 for each langs). What I have works about 95%. The problem is, in the first langs array, one of the 3 randomly picked values is almost always empty, and its not always the same element. Sometimes its the first, sometimes its the third, sometimes its the second... I think I've narrowed down the issue to line 44 ($qtemp = ...). If I change the min/max values for the mt_rand function, it behaves slightly differently. Any help is much appreciated! Thanks in advance.

I'm not overly advanced with my use of arrays, so I'd like some help here if anyone knows what I am looking for. I have a form that I would like to submit to a MySQL database. In that form, there is the ability to add up to 3 harddrives: Code: [Select] Brand: <input type="text" name="hdds[0][hddbrand]" id="hddbrand"><br/> Model and/or size,type: <input type="text" name="hdds[0][hddtype]" id="hddtype"><br/> SN: <input type="text" name="hdds[0][hddsn]" id="hddsn"><br/> Notes: <input type="text" name="hdds[0][hddnotes]" id="hddnotes" size="50"> Obviously the next harddrive would be hdds[1][hddbrand], etc. I am having an awful time looping through this to get more than 1 harddrive's information, however. I've tried foreach embedded in foreach and been messing around with this for a good 3-4 hours now and I feel like I am just missing something. I've got this right now to debug: Code: [Select] foreach($_POST['hdds'] as $key => $a) { $hddbrand = $a['hddbrand']; } my print_r($a) comes up with the following: Code: [Select] Array ( [hddbrand] => Toshiba [hddtype] => Shaba 500gb [hddsn] => 5fu8bvw4 [hddnotes] =>none ) 1 Good. That's what I want. But I need some help constructing my array/loop to get the values of more than 1 drive should I have to enter information for more than 1 drive. I feel like I am close, but I am just not getting what I need. I have not had to work with multidimensional arrays before and they are proving to be more trickier than I expected. Any help would be enormously appreciated! Patrick I am looking at the code below: Code: [Select] $array = array( array( 1, 2 ), 'a' => array( 'b' => 1, 'c' ) ); Is this an example of a multidimensional array? If so how would I access the value of 1 from key b? Also would the next line ('c') be automatically assigned to the asociative key of c? I need to extract data from a CSV file and insert it into a MySQL database. I am able to extract the data, however I cannot figure out how to group it.
