I have this loop, where I'm trying to generate an array like this:
array( $file['file_type'] => $file['import_status] )
To do so, I build this foreach loop to access the $file variable, which has the data I wanted to store.
$filesStatusArray = array();
foreach ($filesToImport as $keys => $file) {
$filesStatusArray = $file['import_status'];
}
This way I'm doing, I have only an array with the import_status values.. but I wanted the key to be the file_type... how can I do that?
$filesStatusArray = array();
foreach ($filesToImport as $keys => $file) {
$filesStatusArray[$file['file_type']] = $file['import_status'];
}

here is what I'm trying to do. I'm retrieving information from a database via array. What is happening is the information from the previous array is going into the next array.
Here is the code:
$i = 0;
foreach ($array_name as $key => test_name) {
$id = $test_name['id']
foreach ($test_name['id] as $key => $test_id {
$data = ModelClass::Information($test_id);
$array_name[$i]['new_infroamtion'] = $data'
}
}
So right now based on the code data from the table is correctly going into the first array, however, information based from the first array is going into the second array..
Let me know if you need anymore information.
Thank you
You are using $array_name while you are iterating through $array_name. This is valid code if you want to do this, but I don't think you do. You need to change the second $array_name to something else.
$i = 0;
foreach (**$array_name** as $key => test_name) {
$id = $test_name['id']
foreach ($test_name['id'] as $key => $test_id {
$data = ModelClass::Information($test_id);
**$array_name**[$i]['new_infroamtion'] = $data
}
}
I did find a solution. What I had to do was add the following
$s = array()
Then in the for loop, I added the following code:
foreach ($test_name['id] as $key => $test_id {
$data = ModelClass::Information($test_id);
$s[] = $data
$array_name[$i]['new_infroamtion'] = $s'
}
I am developing a search engine with vector space Model. I successfully computed tf-idf with associative array data already define in code. Now I want that data should be come from directory where I have a folders and in each folder there is a number of text files with dummy data. I have tried alot but stuck at 1 point using glob function because I want all .txt files as key and its contents as value in foreach loop of glob function.... Below is my code.
Tf-idf With Associative Array Data
$collection = array(
1 => 'this string is a short string but a good string',
2 => 'this one isn\'t quite like the rest but is here',
3 => 'this is a different short string that\' not as short'
);
$dictionary = array();
$docCount = array();
foreach($collection as $docID => $doc) {
$terms = explode(' ', $doc);
$docCount[$docID] = count($terms);
foreach($terms as $term) {
if(!isset($dictionary[$term])) {
$dictionary[$term] = array('df' => 0, 'postings' => array());
}
if(!isset($dictionary[$term]['postings'][$docID])) {
$dictionary[$term]['df']++;
$dictionary[$term]['postings'][$docID] = array('tf' => 0);
}
$dictionary[$term]['postings'][$docID]['tf']++;
}
}
$temp = ('docCount' => $docCount, 'dictionary' => $dictionary);
As you see in 1st foreach loop is that $DocID is key and $doc is its contents(value) of collection array. But I don't know how to implement exact same thing when files read from directory. See code below..
Tf-idf With .txt Files and its contents read from directory
foreach (glob("C:\\wamp\\www\\Web-info\\documents\\awd_1990_00\\*.txt") as $file) {
$file_handle = fopen($file, "r");
//echo $file;
$dictionary = array();
$docCount = array();
foreach($file as $docID=> $value) {
echo $value;
$terms = explode(' ', $doc);
$docCount[$docID] = count($terms);
foreach($terms as $term) {
if(!isset($dictionary[$term])) {
$dictionary[$term] = array('df' => 0, 'postings' => array());
}
if(!isset($dictionary[$term]['postings'][$docID])) {
$dictionary[$term]['df']++;
$dictionary[$term]['postings'][$docID] = array('tf' => 0);
}
$dictionary[$term]['postings'][$docID]['tf']++;
}
}
}
$temp = array('docCount' => $docCount, 'dictionary' => $dictionary);
This gives me error on 1st foreach loop that invalid arugument supplied for foreach loop. As I mentioned earlier I want .txt files as a key and its contents as a value in 1st foreach loop. But I got this error Can anybody please Tell me how to do this.. Thanks in advance..
If you want to treat the entire file as one value, you can use file_get_contents() to read the file into a string:
$dictionary = array();
$docCount = array();
foreach (glob("C:\\wamp\\www\\Web-info\\documents\\awd_1990_00\\*.txt") as $docID) {
$value = file_get_contents($docID);
...
}
I have a loop and each time the loop runs I need to add two variables to an array. What I am trying right now is:
$attach_array['outline'] = array();
foreach ($_POST['attachment'] as $key => $value) {
$attachmentName = $value['name'];
$path = "1";
$name = "alsdkjf";
$attach_array['outline']['path']=$path;
$attach_array['outline']['name']=$name;
}
Then later in the script I try to get these values out for PHPMAILER:
foreach ($attach_array['outline'] as $key => $value) {
$mail->AddAttachment($value['path'], $value['name']);
}
This and other attempts are not working so I'm hoping for some help on putting $name and $path into an array in my first loop to use later.
You are overriding the same variables on each loop. You should do something like this:
$attach_array['outline'][] = array('path' => $path, 'name' => $name);
By doing this, now all the path and values will remain on the array as separate items. You dont have to change the code you are using it from.
i've a 2-dimensional array and i want to push values to it with a while loop like;
$arr[0][1] = 1. value
$arr[0][2] = 2. value
i ve tried
while($zRow = mysql_fetch_array($zQuery))
{
$props[]['name'] =$zRow['name'];
$props[]['photo'] =$zRow['thumbnail'];
}
this loop pushes name to $props[0][name] and thumbnail to $props[1][photo]
i also tried
$j = 0;
while($zRow = mysql_fetch_array($zQuery))
{
$props[$j]['name'] =$zRow['name'];
$props[$j]['photo'] =$zRow['thumbnail'];
$j+=1;
}
that works but with this i when i use foreach loop later, it makes trouble like "Illegal offset type"
and here is my foreach loop
foreach($props as $no)
{
echo $props[$no]['name'];
}
now my questions;
1) are there any other way than while loop with $j variable like array_push for 2-dimensional arrays
2)how can i use foreach loop for 2-dimensional arrays
You could change the first loop to the following:
while($zRow = mysql_fetch_array($zQuery))
{
$row = array();
$row['name'] = $zRow['name'];
$row['photo'] = $zRow['thumbnail'];
$props[] = $row;
}
Your method also works, but you need that extra variable.
In your second loop, what you actually need to be doing is:
foreach($props as $index => $array)
{
echo $props[$index]['name'];
// OR
echo $array['name'];
}
Pushing anything onto an array with $myArray[] = 'foo' will increment the array's counter.
For multidimensional array, you need to populate the "inner" array, then push it to the "outer" (in your case $props) array.
while($zRow = mysql_fetch_array($zQuery)) {
$data = array('name' => $zRow['name'], 'photo' => $zRow['thumbnail']);
$props[] = $data;
}
To iterate over multidimensional arrays whose depth is known:
foreach ($props as $prop) {
foreach ($prop as $key => $value) {
echo "{$key} => {$value}" . PHP_EOL;
}
}
If the depth of the nesting is not known, you may have to use a recursive function to gather the data.
I have the following code:
$rt1 = array
(
'some_value1' => 'xyz1',
'some_value2' => 'xyz2',
'value_1#30'=>array('0'=>1),
'value_2#30'=>array('0'=>2),
'value_3#30'=>array('0'=>3),
'value_1#31'=>array('0'=>4),
'value_2#31'=>array('0'=>5),
'value_3#31'=>array('0'=>6),
'some_value3' => 'xyz3',
'some_value4' => 'xyz4',
);
$array_30 = array
(
'0'=>1,
1=>'2',
2=>'3'
);
$array_31 = array
(
'0'=>4,
'1'=>'5',
'2'=>'6'
);
I need to make it an array and insert the array_30 and array_31 into a DB.
foreach($rt1 as $value){
$rt2[] = $value['0'];
}
The question was updated, so here is an updated answer. Quick check, you should really try and update this to whatever more generic purpose you have, but as a proof of concept, a runnable example:
<?php
$rt1 = array
(
'some_value1' => 'xyz1',
'some_value2' => 'xyz2',
'value_1#30'=>array('0'=>1),
'value_2#30'=>array('0'=>2),
'value_3#30'=>array('0'=>3),
'value_1#31'=>array('0'=>4),
'value_2#31'=>array('0'=>5),
'value_3#31'=>array('0'=>6),
'some_value3' => 'xyz3',
'some_value4' => 'xyz4',
);
$finalArrays = array();
foreach($rt1 as $key=>$value){
if(is_array($value)){
$array_name = "array_".substr($key,-2);
${$array_name}[] = $value['0'];
}
}
var_dump($array_30);
var_dump($array_31);
?>
will output the two arrays with the numbers 1,2,3 and 4,5,6 respectivily
i assume you want to join the values of each of the second-level arrays, in which case:
$result = array();
foreach ($rt1 as $arr) {
foreach ($arr as $item) {
$result[] = $item;
}
}
Inspired by Nanne (which reminded me of dynamically naming variables), this solution will work with every identifier after the \#, regardless of its length:
foreach ( $rt1 as $key => $value )
{
if ( false == strpos($key, '#') ) // skip keys without #
{
continue;
}
// the part after the # is our identity
list(,$identity) = explode('#', $key);
${'array_'.$identity}[] = $rt1[$key]['0'];
}
Presuming that this is your actual code, probably you will need to copy the array somewhere using foreach and afterwards create the new array as you wish:
foreach($arr as $key => $value) {
$arr[$key] = 1;
}
