foreach($sliders as $sKey=>$sVal)
{
echo $sKey.'=>'.$sVal['url'].' image=>'.$sVal['image'].'<br>';
}
?>
And my sorting key is
$sort[]='2,4,5,3,1';
And I want result like this.
array(
1=>array('url'=>"url2.com",'image'=>"img2.jpg"),
2=>array('url'=>"url4.com",'image'=>"img4.jpg"),

4=>array('url'=>"url3.com",'image'=>"img3.jpg"),
5=>array('url'=>"url1.com",'image'=>"img1.jpg"));
How can I sorting Array like this?
Thanks.
I cannot believe that you did not find this yourself...
<?php
$newArray = array();
$sortArray = explode(',', $sort[0]);
$i = 1;
foreach ($sortArray as $s) {
if (isset($sliders[$s])) {
$newArray[$i] = $sliders[$s];
$i++;
}
}

Finding the subsets of an array in PHP
(5 answers)
Closed 7 years ago.
I will do my best to explain this idea to you. I have an array of values, i would like to know if there is a way to create another array of combined values. So, for example:
If i have this code:
array('ec','mp','ba');
I would like to be able to output something like this:
'ec,mp', 'ec,ba', 'mp,ba', 'ec,mp,ba'
Is this possible? Ideally i don't want to have duplicate entries like 'ec,mp' and 'mp,ec' though, as they would be the same thing
You can take an arbitrary decision to always put the "lower" string first. Once you made this decision, it's just a straight-up nested loop:
$arr = array('ec','mp','ba');
$result = array();
foreach ($arr as $s1) {
foreach ($arr as $s2) {
if ($s1 < $s2) {
$result[] = array($s1, $s2);
}
}
}
You can do it as follows:
$arr = array('ec','mp','ba', 'ds', 'sd', 'ad');
$newArr = array();
foreach($arr as $key=>$val) {
if($key % 2 == 0) {
$newArr[] = $val;
} else {
$newArr[floor($key/2)] = $newArr[floor($key/2)] . ',' . $val;
}
}
print_r($newArr);
And the result is:
Array
(
[0] => ec,mp
[1] => ba,ds
[2] => sd,ad
)
Have you looked at the function implode
<?php
$array = array('ec','mp','ba');
$comma_separated = implode(",", $array);
echo $comma_separated; // ec,mp,ba
?>
You could use this as a base for your program and what you are trying to achieve.

How does PHP 'foreach' actually work?

Closed 8 years ago.
$arr = array(1,2,3,4,5);

//output is 22222, why?
Why the result is not 12345?
if you want the output to be 12345:
$arr = array(1,2,3,4,5);
foreach($arr as $key => $val) {
echo $val;
}

Two arrays in foreach loop
(24 answers)
Closed 8 years ago.
I am facing problem when I am trying to insert values from array to mysql database.
foreach ( $_POST['product_id'] as $key=>$value AND $_POST['discount'] as $key1=>$discount) { }
check the above given code where I am going wrong?
You can use a regular for loop as long as the indexes match:
$count = count($_POST['product_id']);
for($i = 0; $i < $count; $i++) {
echo $_POST['product_id'][$i];
echo $_POST['discount'][$i];
}
use array_map this will loop through all keys in all arrays provided simultaneously.
array_map(function(){
$args = func_get_args();
foreach($args as $k => $v) {
echo $v;
}
}, $arr1, $arr2 ...);
