I am trying to display a number that has the english comma separation.
This code gets the number of likes from multiple pages and displays them in a list ordered by number of facebook likes.
function array_sort($array, $on, $order=SORT_ASC)
{
$new_array = array();
$sortable_array = array();
if (count($array) > 0) {
foreach ($array as $k => $v) {
if (is_array($v)) {
foreach ($v as $k2 => $v2) {
if ($k2 == $on) {
$sortable_array[$k] = $v2;
}
}
} else {
$sortable_array[$k] = $v;
}
}
switch ($order) {
case SORT_ASC:
asort($sortable_array);
break;
case SORT_DESC:
arsort($sortable_array);
break;
}
foreach ($sortable_array as $k => $v) {
$new_array[$k] = $array[$k];
}
}
return $new_array;
}
function getLikes($arr){
$urls = "";
// Add urls to check for likes
for($i = 0;$i < count($arr);$i++) {
if($urls != "") $urls .= ",";
$urls .= $arr[$i];
}
// Retreive info from Facebook
$xml = simplexml_load_file("http://api.facebook.com/restserver.php?method=links.getStats&urls=" . $urls);
$likes = array();
// Loop through the result and populate an array with the likes
for ($i = 0;$i < count($arr);$i++) {
$url = $xml->link_stat[$i]->url;
$counts = (int)$xml->link_stat[$i]->like_count;
$likes[] = array('likes' => $counts,'url' => $url);
}
return $likes;
}
$array = array("URL HERE","URL HERE");
$likes = getLikes($array);
$likes = array_sort($likes, 'likes', SORT_DESC);
$english_format_number = number_format($likes, 'likes');
foreach ($likes as $key => $val) {
echo "<li class='facebook'><div class='fb-page'><div class='rank'>" . $key . "</div>" . "<div class='thumb " . $val['url'] . "'><div class='link'>" . $val['url'] . "</div></div>" . "<div class='likes'>" . $val['likes'] . "</div></div></li><br />";
}
The code works fine, by the way I am not a coder, and am only just getting into it.
I was trying to add in something like
$english_format_number = number_format($likes, 'likes');
But of course I have no idea if I can do that or where to put it.
Can anyone help?
you use wrong parameter in number_format function. the correct format is number_format(number,decimals,decimalpoint,separator). so change you code to
$english_format_number = number_format($likes, 0, ',', '.') . 'likes';

I have the results of a mysql query, I'd like to add a new field and populate with a calculated value that I'd like to then sort by, I'm new with adding fields to arrays and sorting of arrays so any help is appreciated, thanks.
$keyArray = explode(" ", $keyPhrase);
$result = $mysqli->query($queryString);
while($row = $result->fetch_array()){
$rows[] = $row;
}
foreach($rows as $row){
$bodyData = $row["bodydata"];
$totalKeys = 0;
foreach($keyArray as $value){
$keyCount = substr_count($bodyData, $value);
$totalKeys = $totalKeys + $keyCount;
}
// Here I'd like to add new field to $rows[]
// with $totalKeys value then sort by it desc after the this loop
}
}
I got it to work like this:
foreach($rows as &$row){
$bodyData = $row["bodydata"];
$totalKeys = 0;
foreach($keyArray as $value){
$keyCount = substr_count($bodyData, $value);
$totalKeys = $totalKeys + $keyCount;
}
$row["sortcount"] = $totalKeys;
}
$rows = array_sort($rows, "sortcount", SORT_DESC);
function array_sort($array, $on, $order=SORT_ASC)
{
$new_array = array();
$sortable_array = array();
if (count($array) > 0) {
foreach ($array as $k => $v) {
if (is_array($v)) {
foreach ($v as $k2 => $v2) {
if ($k2 == $on) {
$sortable_array[$k] = $v2;
}
}
} else {
$sortable_array[$k] = $v;
}
}
switch ($order) {
case SORT_ASC:
asort($sortable_array);
break;
case SORT_DESC:
arsort($sortable_array);
break;
}
foreach ($sortable_array as $k => $v) {
$new_array[$k] = $array[$k];
}
}
return $new_array;
}
$array = ['coke.','fanta.','chocolate.'];
foreach ($array as $key => $value) {
if (strlen($value)<6) {
$new[] = $value." ".$array[$key+1];
} else {
$new[] = $value;
}
}
This code doesn't have the desired effect, in fact it doesn't work at all. What I want to do is if an array element has string length less than 5, join it with the next element. So in this case the array should turn into this:
$array = ['coke. fanta.','chocolate.'];
$array = ['coke.','fanta.','chocolate.', 'candy'];
$new = [];
reset($array); // ensure internal pointer is at start
do{
$val = current($array); // capture current value
if(strlen($val)>=6):
$new[] = $val; // long string; add to $new
// short string. Concatenate with next value
// (note this moves array pointer forward)
else:
$nextVal = next($array) ? : '';
$new[] = trim($val . ' ' . $nextVal);
endif;
}while(next($array));
print_r($new); // what you want
Live demo
With array_reduce:
$array = ['coke.', 'fanta.', 'chocolate.', 'a.', 'b.', 'c.', 'd.'];
$result = array_reduce($array, function($c, $i) {
if ( strlen(end($c)) < 6 )
$c[key($c)] .= empty(current($c)) ? $i : " $i";
else
$c[] = $i;
return $c;
}, ['']);
print_r($result);
demo
<pre>
$array = ['coke.','fanta.','chocolate.'];
print_r($array);
echo "<pre>";
$next_merge = "";
foreach ($array as $key => $value) {
if($next_merge == $value){
continue;
}
if (strlen($value)<6) {
$new[] = $value." ".$array[$key+1];
$next_merge = $array[$key+1];
} else {
$new[] = $value;
}
}
print_r($new);
</pre>
Updated Code after adding pop after chocolate.
<pre>
$array = ['coke.','fanta.','chocolate.','pop'];
print_r($array);
echo "<br>";
$next_merge = "";
foreach ($array as $key => $value) {
if($next_merge == $value){
continue;
}
if (strlen($value)<6 && !empty($array[$key+1])) {
$new[] = $value." ".$array[$key+1];
$next_merge = $array[$key+1];
} else {
$new[] = $value;
}
}
print_r($new);
<pre>
You need to skip the iteration for the values that you have already added.
$array = ['coke.', 'fanta.', 'chocolate.'];
$cont = false;
foreach ($array as $key => $value) {
if ($cont) {
$cont = false;
continue;
}
if (strlen($value) < 6 && isset($array[$key+1])) {
$new[] = $value.' '.$array[$key+1];
$cont = true;
}
else {
$new[] = $value;
}
}
print_r($new);
I have the following array:
$array = [
['2017-02-26', '2017-02-27'],
['2017-03-01'],
['2017-01-01', '2017-01-02', '2017-01-03', '2017-01-04'],
['2017-01-05', '2017-01-06', '2017-01-07']
];
I'm looking to loop into this array to have something like this:
// When several dates
From 2017-02-26 to 2017-02-27.
// When only one date
On the 2017-03-01.
What I tried:
foreach ($array as $key => $value) {
$count = count($array[$key]);
if($count==1) {
echo "On the $key[$value]";
}
else {
$first = reset($array);
$last = end($array);
echo "From ".$first." to ".$last.;
}
}
But it doesn't work when there is only one date in the row.
You are looping by foreach() so it will display last echo string .Store result to one variable Eg($display) will be more easy to display that
$display = "";
foreach ($array as $key => $value) {
$count = count($array[$key]);
if($count==1) {
$display .= "On the $value[0] <br>";
}
else {
$first = $value[0];
$last = $value[$count-1];
$display .= "From ".$first." to ".$last."<br>";
}
}
echo $display;
Try this:-
foreach ($array as $key => $value) {
$count = count($value);
if($count==1) {
echo "On the ".$value[0];
}
else {
$first = reset($value);
$last = end($value);
echo "From ".$first." to ".$last;
}
}
Or just copy paste this code, it will work. Your main inside array to play with is $value.
I currently have coded a way to turn a multidimensional array to comma separated values (I'm using pipes instead of commas for ease of debugging). The problem is, I know that the code I use to do this is bloody awful. It works how I want it to, but it's not nice at all.
What I need
Currently the arr_to_csv() function works for five levels of nested data within the multidimensional array. I need a recursive function to perform the same for one or an unlimited number of nested arrays, or a good nudge in the right direction. Recursion is not my strong point at all, but I know it's the way forward.
Data input
A multi-dimensional array is passed to the function.
array
'name' =>
array
'singular' => null
'plural' => null
'fields' =>
array
'price' =>
array
'label' => string 'Preis' (length=5)
'company_id' =>
array
'label' => null
'placeholder' => null
//...the array could go on...
The function returns the following...
This is exactly what I want...
0 => string 'name||singular||null' (length=20)
1 => string 'name||plural||null' (length=18)
2 => string 'fields||price||label||Preis' (length=27)
3 => string 'fields||company_id||label||null' (length=31)
4 => string 'fields||company_id||placeholder||null' (length=37)
5 => string 'fields||name||label||null' (length=25)
6 => string 'fields||name||placeholder||null' (length=31)
My horrible constructed function
I'm no good with recursion, so here's my awful list of foreachs. As you can see from the below code, this is terrible (no need to read the whole thing, it just copies itself). Please help me sort out my horrible code!
function arr_to_csv($data,$csv = '||') {
$array = array();
/* Epic amount of for each's. This could be done with recursion */
foreach($data as $key => &$value) {
if (!is_array($value)) {
$array[] = $key . $csv .(is_null($value)?'null':$value);
} else {
foreach ($value as $k => &$v) {
if (!is_array($v)) {
$array[] = $key . $csv . $k . $csv . (is_null($v) ? 'null' : $v);
} else {
foreach ($v as $kk => &$vv) {
if (!is_array($vv)) {
$array[] = $key . $csv . $k . $csv . $kk . $csv . (is_null($vv) ? 'null' : $vv);
} else {
foreach ($vv as $x => &$y) {
if (!is_array($y)) {
$array[] = $key . $csv . $k . $csv . $kk . $csv. $x . $csv . (is_null($y) ? 'null' : $y);
} else {
foreach ($y as $too => $long) {
if(!is_array($long)) {
$array[] = $key . $csv . $k . $csv . $kk . $csv. $x . $csv . $too . $csv. (is_null($long)?'null':$long);
} else {
foreach ($long as $omg => $why) {
if(!is_array($why)) {
$array[] = $key . $csv . $k . $csv . $kk . $csv. $x . $csv . $too . $csv . $omg . $csv . (is_null($why) ? 'null' : $why);
}
}
}
}
}
}
}
}
}
}
}
}
return $array;
}
This is some pseudocode, but it is a start:
$strings = [];
$flattenArray = function($arr, $level) use (&$strings, &$flattenArray) {
foreach($arr as $key=>$value){
$s = &$strings[$level];
if(!isset($s)) { $s = array(); }
$s[] = $key;
if(is_array($value)) {
$flattenArray($value, $level);
}
else {
$s[] = $value;
}
$level ++;
}
};
$flattenArray($myArray, 0);
foreach($strings as &$arr) {
$arr = implode("||", $arr);
}
Small demo with your array: http://codepad.viper-7.com/CR2SPY <-- It does not work fully, but it is a start
Update:
Here is a demo that I think works the way you want: http://codepad.viper-7.com/shN4pH
Code:
$strings = [];
$flattenArray = function($arr, $level, $k = null) use (&$strings, &$flattenArray) {
foreach($arr as $key=>$value){
if($k === null) {
$s = &$strings[$key];
}
else {
$s = &$strings[$k];
}
if(!isset($s)) {
$s = array();
}
$str = &$s[$level];
if(!isset($str)) {
$str = array();
if($k !== null) { $str[] = $k; }
}
$str[] = $key;
if(is_array($value)) {
$flattenArray($value, $level, ($k === null) ? $key : $k);
}
else {
$str[] = is_null($value) ? "null" : $value;
}
$level ++;
}
};
$flattenArray($myArray, 0);
$all = [];
foreach($strings as $k => $arr){
$new = array();
foreach($arr as $ky => $ar) {
$all[] = implode("||", $ar);
}
}
print_r($all);
I didn't check it, so in case it doesn't work it should be corrected.
function readarray($from_array, $addr = array()) {
global $output;
foreach ($from_array as $key => $value) {
if (is_Array($value) && count($value) > 0) {
$addr[] = $key;
readarray($value, $addr);
} else {
$output[] = implode('||', $addr) . $value;
}
}
}
$output = array();
foreach ($my_array as $key=>$value){
readarray($value);
}
// improved to get separate arrays of the root of initial array
Not sure if this will help you, but would it not be easier to flatten the array first and then format in in the way you want? To flatten the array try this:
$array = "YOUR ARRAY";
$FlatArray = array();
foreach(new RecursiveIteratorIterator(new RecursiveArrayIterator($array)) as $k=>$v)
{
$FlatArray[$k] = $v;
}
Been trying all morning to come up with a recursive function for this. This is as close as I got, Maybe you can improve upon this.
$data = array('name' =>array('singular' => NULL,'plural' => NULL,'fields' =>array('price' =>array('label' =>'Preis','company_id' =>array('label' => NULL,'placeholder' => NULL)))));
function arr_to_csv($data,$csv = '||')
{
$list = "";
foreach($data as $key => &$value)
{
$list .= $key . $csv .((!is_array($value))?(is_null($value)?'null':$value): arr_to_csv($value))."<br>";
}
return $list;
}
print_r(arr_to_csv($data));
Returns This:
name||singular||null
plural||null
fields||price||label||Preis
company_id||label||null
placeholder||null
I have an array which i do a foreach($array as $key => $value)
in my $key i get
name[1][1]
name[1][2]
name[1][3]
name[2][1]
name[2][2]
how can I add detect when the first index changes from [1][3]->[2][1]
any help is appreciated.
What i want to achieve is this:
<h4>Header</h4>
name[1][1]
name[1][2]
name[1][3]
<h4>Header</h4>
name[2][1]
name[2][2]
<h4>Header</h4>
name[3][1]
name[3][2]
name[3][3]
name[3][4]
Don't know if it is the best option, but this is how i managed to do it.
<?php $k = 1; $flag1 = 0; $flag2 = 1;foreach ($this->cart->product_options($items['rowid']) as $option_name => $option_value): ?>
<?php
$endpos = strpos($option_name,']');
$asd = substr($option_name,5,$endpos-5);
$this->firephp->log($asd);
if($asd % 2)
{
if($flag1 === 0)
{
echo ' <h4>Header '. $k .'</h4>';
$flag1 = 1;
$flag2 = 0;
$k++;
}
}
else
{
if($flag2 === 0)
{
echo ' <h4>Header '. $k. '</h4>';
$flag2 = 1;
$flag1 = 0;
$k++;
}
}
?>
You can try like
foreach($name as $parent_key => $parent_value){
echo "<h4>Header</h4><br/>";
foreach($name[$parent_key] as $key=>$value)
{
echo $name[$i][$key]."<br/>";
}
}
foreach($array as $key => $value){
$valuevalues = array();
foreach($value as $val){
if($val != "" && !isset($valuevalues[$key][$val]))
$valuevalues[$key][$val] = "different-than-previous";
if(!isset($valuevalues[$key][$val]))
$valuevalues[$key][$val] = "equal-to-first-value";
}
}
