My graph is not getting generated properly with Chartist graph library It wants data generated as series: [ [2,4,5,5,6], [6,4,8,7] ] I tried to do it with this
<?php echo "[". $comma_separated."],[". $comma_separated1."]"?>
$comma_separated = [2,4,5,5,6] $comma_separated1 = [6,4,8,7]
and I want $result = [ [2,4,5,5,6] , [6,4,8,7] ]
but only first array gets displayed in graph not second one ie $comma_separated1. Static entry of these things is generating it properly.
Is there any way that I can join these two strings into a single one with a "],[" between them and not between the contents in array.
Instead of creating the string manually, if both are already in array form, just use json_encode, you wouldn't need to manually add each string if the batches continue to grow:
// example input
$comma_separated = array(1, 2, 3, 4, 5); // 1 - 5
$comma_separated2 = array(6, 7, 8, 9, 10); // 6 - 10
$result = json_encode(array($comma_separated, $comma_separated2));
echo $result; // [[1,2,3,4,5],[6,7,8,9,10]]
The example above parses them from an array form into string. If the input came from a string form (literal comma delimited string), then you need to explode it first, then cast all elements with int, so that in turn json_encode will treat them as int:
// example input
$comma_separated = '1,2,3,4,5';
$comma_separated2 = '6,7,8,9,10';
// int casting
$comma_separated = array_map('intval', explode(',', $comma_separated));
$comma_separated2 = array_map('intval', explode(',', $comma_separated2));
$result = json_encode(array($comma_separated, $comma_separated2));
echo $result; // [[1,2,3,4,5],[6,7,8,9,10]]
Hope the mentioned helps you.
<?php
$array1 = array('2','4','5','5','6');
$array2 = array('6','4','8','7');
$finalString = array($array1, $array2);
print "<pre>";
print_r($finalString);
print "</pre>";
?>
