I have print_r array like this. How do I SUM field 'credit' ?
I want to result like this in html :
650000
500000
500000
500000
200000
you can create funtion to sum your array
function sum_credit($array){
$sum = 0;
foreach($array as $val){
$sum += $val->credit;
}
return $sum;
}
and print your data with
echo sum_credit($array);
$creditSum = array_sum(array_column($array,'credit'));
With array_column, a one-dimensional array is created from 'credit' values and then the sum is calculated with array_sum.

this is my array:
$a = [1,2,3,4,5];
Processed format：
1,2
1,3
1,4
1,5
2,3
2,4
2,5
3,4
3,5
4,5
The two elements are a group. If only the last element is left, it ends.
Like so:
$a = [1,2,3,4,5];
foreach($a as $key => $value)
{
for($i = $key + 1; $i < count($a); $i++)
{
echo $value.",".$a[$i]."\n";
}
}

I have arraylist like : [1, 2, 3, 4, 5];
How can I get each of these values in php?
Is there any function ? I tried array() but it did not return anything.I really appreciate any help.
Let say your $array = [1,2,3,4,5];
To get the values:
foreach($array as $values):
echo $values.'<br/>';
endforeach;
Or if you want based on elements, you can get by this way:
//To get value 1
echo $array[0];
// 0 being here the index of your array
// so echo $array[0] will output 1 since it's the first key of your array
If you have an array like this
$numbers = array(1,2,3,4,5);
with five values (i.e indexed 0 - 4) you can print out all values in the array using the print_r() function like this:
print_r($numbers);
Or you can loop through every element in the array with any PHP looping statement like FOR STATEMENTS, FOREACH STATEMENTS, WHILE STATEMENTS..
e.g
foreach($numbers as $num){
echo $num;
echo '<br/>';
}
You can also get a single value from the array using the index for example my array has 5 values (indexed from 0 - 4) if i want to print out the number '3' i would write
echo $numbers[2];

In my array I have these values:
[10d, 10e] => 4
The values are retrieved from another website and the important values will be put in this array.
Now I want to have two single values from these like:
[10d] => 2 [10e] => 2
How can I do this?
Now I'm guessing a little because of the description that is not that clear.
$arr = array('10d, 10e' => 4);
$newArr = array();
foreach($arr as $key => $value) {
$newKeys = explode(',', $key);
foreach($newKeys as $item) {
$newArr[trim($item)] = $value / count($newKeys);
}
}
print_r($newArr);
Result
[10d] => 2 [10e] => 2
Some functions you can use:
foreach() to loop the input array
explode() to split the key
trim() to remove whitespace
count() to, well, count array items
And, of course, / to divide ;-)

i have associate array like this :
$json_data = array();
$jason_data[]= array ('id'=>'1','brand'=>'chanel','name'=>'red');
$jason_data[]= array ('id'=>'3','brand'=>'lacoste','name'=>'green');
$jason_data[]= array ('id'=>'1','brand'=>'chanel','name'=>'red');
$jason_data[0] and $jason_data[2] are Equal
i want find in $jason_data for equal array and echo them
I don't know whats the context of this and your question is vague, but anyway, I hope this is what you want to achieve. (and your variable naming is odd). In your example index zero and two are the same, and since they are multi-dimensional, you can flatten them in a way by using serialize. Try this:
$json_data = array();
$json_data[]= array ('id'=>'1','brand'=>'chanel','name'=>'red');
$json_data[]= array ('id'=>'3','brand'=>'lacoste','name'=>'green');
$json_data[]= array ('id'=>'1','brand'=>'chanel','name'=>'red');
$json_data = array_map('serialize', $json_data);
$values = array_count_values($json_data);
echo '<pre>';
foreach($values as $array => $count) {
if($count > 1) {
$array = unserialize($array);
print_r($array);
}
}
Should output/print the ones that has duplicates:
Array
(
[id] => 1
[brand] => chanel
[name] => red
)

How can I add new item to array? For example into middle of an array ?Should we use array splice or an array merge ?
Could you explain me the difference between both function ?
Say I have
$a1=array("a"=>"Horse","b"=>"Dog","c"=>"Cow",);
$a2=array("d"=>"Cat");
Now I need to add $a2 in 2 position .
Which one should I use ?
You can use array_splice, except that won't keep your keys.
$a1 = array("a"=>"Horse", "b"=>"Dog", "c"=>"Cow");
$a2 = array("d"=>"Cat");
array_splice($a1, 2, 0, $a2);
// $a1 is now: array("a"=>"Horse", "b"=>"Dog", 0=>"Cat", "c"=>"Cow");
If you want Cat to have a key of d, you can use a mix of array_slice and the array union operator (+):
$a1 = array_slice($a1, 0, 2) + $a2 + array_slice($a1, 2);
// $a1 is now: array("a"=>"Horse", "b"=>"Dog", "d"=>"Cat", "c"=>"Cow");
you can use array_push to add array at any position. ..array_splice can also be used. .
example: array_splice
