[SOLVED] Echo section of array where key = value

[andrewgarn]

This is probably simple, but i'm not making it work.

 

I have a n array which contains a set of values, each of these values are one of the possible values in another array

 

What i want to do, is for each of the values in the first array, echo the coresponding values in the second.

 

I have this:

 

<?php
$result = array_unique($keynb);
foreach($result as $value)
{
$check = array_search($value, $keynb);
print_r($check);
}

 

This only prints one of the keys of each value.

Perhaps you should give an example of the two arrays, but perhaps array_intersect might be of use?

[andrewgarn]

and I forgot the $keynb array is sorted by value using: asort($keynb);

 

print_r($keynb);

[syktt] => 1 [sewsgc] => 1 [lbdxn] => 1 [ttjklz] => 1 [lrvht] => 1 [tmdec] => 1 [internal] => 2 [structures] => 2 [demands] => 2 [coherent] => 2 [content] => 2 [imposition] => 2 [fourth] => 2 [second] => 2 [third] => 2 [fifth] => 2 [distinguished] => 2 [reason] => 2 [treated] => 2 [unrelated] => 2 [courses] => 2 [different] => 2 [memorised] => 2 [intrinsic] => 2 [deepsurface] => 2 [slide] => 2 [distinguishes] => 2 [conversational] => 2 [nthpr] => 2 [experience] => 2 [signs] => 2 [associated] => 2 [concepts] => 2 [argument] => 2 [unreflectively] => 2 [evidence] => 2 [everyday] => 2 [theoretical] => 2 [master] => 3 [however] => 4 [succeed] => 4 [present] => 4 [provides] => 4 [challenge] => 4 [motivation] => 4

 

print_r($result);

[click] => 1 [internal] => 2 [master] => 3 [however] => 4 [important] => 5 [styles] => 6 [questions] => 7 [skill] => 8 [cognitive] => 9 [groups] => 10 [skills] => 12 [ideas] => 14 [teacher] => 16 [model] => 17 [group] => 20 [within] => 22 [which] => 24 [models] => 25 [behavior] => 28 [based] => 29 [their] => 40 [knowledge] => 42 [learners] => 44 [learning] => 67

 

For $result, all i want to use is the values, as i am trying to find all the words with the same number of occurrences.

 

I can turn $result into a string by doing:

 

foreach($result as $value)
{
$stnb = $stnb.' '.$value;
} 

echo $stnb;

 

Gives: 1 2 3 4 5 6 7 8 9 10 12 14 16 17 20 22 24 25 28 29 40 42 44 67

So...basically you want to somehow link for instance

 

click: syktt sewsgc lbdxn ttjklz lrvht tmdec

 

?

[andrewgarn]

Each word in $keynb has a value associated with it. (This value is the number of times a word has appeared in a document)

 

These values are stored in $result.

 

All I want to do is echo the words that correspond to each value so:

 

Number 1

 

//all words with value of 1

 

Number 2

 

//all words with value of 2

[andrewgarn]

No luck so far.

Sorry bro I really don't understand what you're trying to accomplish.  You say that your first array has words as keys and the values are how many times they appear in some document, right? Easy enough to understand.  But then you say something about how the values are also somehow stored in your second array.  But then you turn around and say that you just want to echo the actual words?  So...I really don't understand what you are trying to accomplish here.

 

-What is the difference between these two arrays?

-Are you trying to make some kind of comparison between the two?

-If all you are trying to do is echo the actual words, use a loop and simply echo them example:

 

foreach($array as $key => $val) {
   echo "$key <br/>";
}

[andrewgarn]

Ignore the second array, I can make that a string, so ignore it.

 

What I want to make is a NEW array with the key being NUMBERS and the values being the words that appeared for that NUMBER of times.

 

So this:

 

[syktt] => 1 [sewsgc] => 1 [lbdxn] => 1 [ttjklz] => 1

 

would become:

 

[1] => syktt, sewsgc, lbdxn, ttjklz

 

etc

 

Hope thats more clear.

[.josh]

foreach($keynb as $key => $val) {
   $newlist[$val] .= $key . " ";
}

[andrewgarn]

Thanks, that works

 

Now to find words that appeared each number of times, i just need to use the numbers from the 2nd array, and echo the new array with that as the key

 

Thanks

do tou mean

    );

$result = array();
foreach ($ar as $word => $count)
{
    $result[$count][] = $word;
}

foreach ($result as $count => $words)
{
    sort($words);
    echo $count, ' : ', join(', ', $words), '<br/>';
}
