Say we have an array like this with 1 being two values and 2 being two values and 3, etc
$language = array
(
"1"=>array
(
"Hola",
"Spanish"
),
"2"=>array
(
"Fáilte",
"Irish"
),
"3"=>array
(
"Yasou",
"Greek"
)
);
How would I randomly select ONLY 1 of 3 arrays and display the two values it has.
So something like this, $language[2][1], thats in $language[2][2].
Which should be, Fáilte, thats in Greek
PHP has it's own random array function: array_rand(). Use it like so:
$random_key = array_rand($language);
echo $language[$random_key][0];
echo $language[$random_key][1];
You can choose a random set of words using the following code and then echo the two results like so:
$row = rand(0,sizeof($language)-1);
echo $language[$row][0];
echo $language[$row][1];
This is assuming that your array actually starts from 0 as most arrays do. If it really starts from 1, you can use the code posted in the answer below instead.

Guys i have maybe a very simple question but i don't know how to make it.
How can i transform a following text into an array of variables.
$NotParsedString = "123456,654987,789456,321465";
foreach($results['data'] as $item){
$PostID = $item['id'];
if($PostID != $AnyIDfromNotParsedString){
echo 'Show this thing';
}
}
Simply i want to remove all the commas from $NotParsedString and make them as alone IDs which i can compare to $PostID and if $PostID is not same as any of theese IDs to echo 'Show this thing';
I hope you get the whole idea of what i am trying to do.
I want something like if $PostID is not equal to 123456 or if $PostID is not equal to 654987 and so on for the ones left till the end.
Can you help me out guys?
Thanks in advance!
Just use in_array() combined with explode() like this:
if(!in_array($PostID, explode(",", $NotParsedString))){
Just use the explode() function.
$NotParsedString = "123456,654987,789456,321465";
$ids = explode(',', $NotParsedString);
$ids will be as following.
Array
(
[0] => 123456
[1] => 654987
[2] => 789456
[3] => 321465
)
I'm having trouble finding the right function to rearrange my multidimensional-array. I will explain using an example.
so i have three different arrays, let's say:
$ID (containing n numbers)
$Name (containing n names)
$Explanation (containing n explanations)
I have tried array($id, $name, $explanation), which returns a new array, containing the above three arrays as they were before. However I would like to have my new array in the following way:
array(
array (1[0], football[0], played on grass[0])
array (2[1], swimming[1], played in the water[1])
array (3[2], diving[2], played under water[2])
....
array (n+1[n], basketball[n], played indoors[n])
)
I would like my array this way so it can be processed more easily into my database. Thanks in advance!
I assume that all the three arrays are equal in length say $arr1,$arr2,$arr3, Try:
$result = array();
foreach($arr1 as $key=>$val){
$result[] = array($val,$arr2[$key],$arr3[$key]);
}
Then for re-indexing result array starting from index 1 you can try like,
$result = array_unshift($result,null);
unset($result[0]);
I'm working on some stat tracking code for a game (yes, it's runescape. sue me).
I want to pull information from the high scores using an api which produces an array looking like this (captured using print_r)
Array
(
[getHiscore] => Array
(
[overall] => Array
(
[rank] => 61995
[lvl] => 2273
[totalxp] => 193310588
)
[attack] => Array
(
[rank] => 93406
[lvl] => 97
[totalxp] => 11747494
)
...and so on.
My question is how can i take what this api gives me and place it into a database table; I want to get an array such as this for a particular user and update their stats with it.
Would i use explode? It seems like the right idea to me but how would i actually use it to split the separate numbers and words?
My database is not totally realised yet, however each record will include a user name and then the level and total xp in each of 27 "skills". This almost certainly not best practice for database design but i'm as novice as they come so it's the best i can do.
You don't need to explode. It's an array and therefore it's already exploded. You need to iterate through it to build meaningful queries.
I'm not familiar with runescape so I don't know if your example is showing just the relevant fields of you need to discard some part. If it's the former, then you should try something like
$query="insert into stats_table (description, rank, lvl, totalexp) values (:description, :rank, :lvl, :totalext);";
$Statement = $DBConn->prepare($query);
foreach($fullArray as $description=>$subArray) {
$Statement->bindValue(':description',$description, PDO::PARAM_STR);
foreach($subArray as $key=>$value) {
$Statement->bindValue($key,$value, PDO::PARAM_STR);
}
$Statement->execute();
}
That will insert two rows containing
overall 61995 2273 193310588
attack 93406 97 11747494
PD: $DBConn is a PDO connection instance to whatever DB engine you're using.
Let's say this is all stored in the variable $ary:
$ary['getHiscore']['overall']['rank'] = 61995;
$ary['getHiscore']['overall']['lvl'] = 2273;
$ary['getHiscore']['overall']['totalxp'] = 193310588;
$ary['getHiscore']['attack']['rank'] = 93406;
$ary['getHiscore']['attack']['lvl'] = 97;
$ary['getHiscore']['attack']['totalxp'] = 11747494;
So, to get those values, it's:
$attackLevel = $ary['getHiscore']['attack']['lvl'];
If you
echo $attackLevel;
it would be 97.
Just pull the arrays out with a foreach loop and write some sql to insert the data. I don't know anything about your DB so if you want help there update your question please.
Simplest way to do this:
foreach($highscores as $highScoreType => $highScoreValues){
$rank = $highScoreValues['rank'];
$lvl = $highScoreValues['lvl'];
$totalXp = $highScoreValues['totalxp'];
//then it's up to you to put it into a table somehow.
}
$highScoreType will contain the values 'overall','attack',etc
This format of the foreach loop is extremely handy when iterating over an associative array (hash map/hash table, which is actually what all PHP arrays are underneath) will allow you to not only grab the value of the current pointed to entry, but also the key for that entry.
So, assume we have a single entry hashmap with key 'foo' and value 'bar'. If I want to show 'bar' I would simple
echo $map['foo'];//will output 'bar'
and if I put this into the above type of foreach loop
foreach($map as $fooKey => $barValue) {
echo $fooKey;//outputs 'foo'
echo $barValue;//outputs 'bar'
}
Here is my code:
<?php
//header code to define as json and if $_GET statement...
$JSONArrayA[$variableA] = array('id' => $idA, 'test' => $testVariableA);
$JSONArrayB[$variableB] = array('id' => $idB, 'test' => $testVariableB);
//current code resulting in ["ArrayArray"]
$FinalJSONArray[] = $JSONArrayA . $JSONArrayB;
echo json_encode($FinalJSONArray);
?>
My question: How do I make the array contain two or more arrays? Any help appreciated.
array_merge
$FinalJSONArray = array_merge($JSONArrayA, $JSONArrayB);
Merges the elements of one or more arrays together so that the values
of one are appended to the end of the previous one. It returns the
resulting array.
If you want to instead return an array containing the other two arrays themselves,
use
$FinalJSONArray = array($JSONArrayA, $JSONArrayB);
Try
$FinalJSONArray[] = $JSONArrayA;
$FinalJSONArray[] = $JSONArrayB;
This will reult in 2 sub arrays. If you want them merged use:
$FinalJSONArray[] = $JSONArrayA+$JSONArrayB;
"+" with two arrays unions them (see: http://php.net/manual/en/language.operators.array.php)
Depending on what you want your JSON to look like
$FinalJSONArray = array($JSONArrayA,$JSONArrayB);
I am trying to merge two parts of a code. To do that i have to store the echo'd array column output from a function which i call on
multiple times into an array or arrays on which I can perform computations.
Here's what i'm trying to do:
<?php
$searchquery[1] ="jupiter";
$searchquery[2] ="venus";
//can be multiple queries
include ('find.php');
for($i=0;$i<count($searchquery);$i++)
{
find($searchquery[$i]);
}
/find.php echoes back to me a MySQL query which then
creates a 2 dimensional array for me called
/$searchresult which looks like this as an example
t x (let's call first column t for example, and second x)
|1|3|
|1|4|
|2|6|
|4|8|
|7|1|
and it echoes it back to me, this works.
But, i need to use the first column (t) (11247) output from find.php
which was the result of the searchquery "jupiter",
and i need to store it as some sort of array in this current sheet,
theni need to store the "venus" searchquery which is let's say
t x
|1|3|
|2|4|
|3|4|
|4|6|
|5|4|
and store the first column (t) as an array in this current sheet.
I am trying to store the echos from the find.php function as arrays so that
i can perform the following operation in the current sheet:
$venusarrayt = array(1, 1, 2, 4, 7); //the manually defined
//$searchresult first column output from find.php which echos to me (t) (11247)
$jupiterarrayt = array(1, 2, 3,4,5); //the manually defined
//$searchresult first column output from find.php which echos to me (t) (12345)
//I need to perform the following operation and sum all of the t combinations
for($l=0;$l<count($venusarrayt);$l++){
for($s=0;$s<count($jupiterarrayt);$s++){
echo $venusarrayt[$l]+$jupiterarrayt[$s];
This part works! But i am having trouble though merging the echo'd $searchresult output into an array on which i can perform the above
for loops. In this example i am doing it by hand by typing into the php sheet "venusarrayt and jupiterarrayt".
I am sure there is some way to store echo'd array column results from a function which i call upon multiple times into an array, but i
haven't figured out yet how. Please help.
I hope this helps:
<?php
$searchquery[0] ="jupiter";
$searchquery[1] ="venus";
//can be multiple queries
include ('find.php');
$results=null;
for($i=0;$i<count($searchquery);$i++)
{
$temp=find($searchquery[$i]);
$results[$i]=$temp[t];
}
for($l=0;$l<count($results[1]);$l++){
for($s=0;$s<count($results[0]);$s++){
echo $results[1][$l]+$results[0][$s];
}
}
Clear solution for anyway of further working with your searched data can looks something like this:
$searchquery[1] ="jupiter";
$searchquery[2] ="venus";
$search_result = array(); $i=0;
foreach($searchquery as $current_query){
$current_result = FindResul($current_query);
// FindResult will be your function which process single query and returns result of it
$search_result[$i]['query'] = $current_query;
$search_result[$i]['result'] = $current_result;
$i++;
}
After the execution the code above you will have array 2-lvl array with clear and easy to work with structure. You can use it how you'd like to compare data or show it in the way you want.
Resulting array will have such structure:
$search_result[0]['query'] = 'jupiter';
$search_result[0]['result'] = '...jupiter resul';
$search_result[1]['query'] = 'venus';
$search_result[1]['result'] = '...venus result';
You have to create nested array to resolve the issue I would give a little example how to do?
$searchquery[1] ="jupiter";
$searchquery[2] ="venus";
for($i=1;$i<=count($searchquery);$i++){
$temp=find($searchquery[$i]);
$results[$i]=$temp[t];
}
$k=$i;
for($z=0;$z<=$i;$z++){
$total='';
for($p=0;$p<=$k;$p++){
$total=$total+$results[$p][$z];
}
echo $total;
echo "\n";
}
function find($word){
return array('t' => array('1', '2', '4', '7'));
}
and answer would be something like this:
Array
(
[1] => Array
(
[0] => 1
[1] => 2
[2] => 4
[3] => 7
)
[2] => Array
(
[0] => 1
[1] => 2
[2] => 4
[3] => 7
)
)
2
4
8
14
This solution will add all the n number of queries first result, second result and so on.......
