I'm trying to add a string to a 3*x Array. I have a string as an input with 150*3 values.
<?php
$myString = "5.1,3.5,Red,4.9,3,Blue,4.7,3.2,Red,4.6,3.1,Red,5,3.6,Red," //and so on
?>
the result should look like
Array
(
[0] => Array
(
[0] => 5.1
[1] => 3.5
[2] => Red
)
[1] => Array
(
[0] => 4.9
[1] => 3
[2] => Blue
)
//and so on
)
First, you will need to convert the comma separated string into an array. Then you can use the array_chunk() function.
$myString = "5.1,3.5,Red,4.9,3,Blue,4.7,3.2,Red,4.6,3.1,Red,5,3.6,Red";
$explodedStringToArray = explode(',', $myString);
$chunked_array = array_chunk($explodedStringToArray, 3);
print_r($chunked_array);
This will produce:
Array
(
[0] => Array
(
[0] => 5.1
[1] => 3.5
[2] => Red
)
[1] => Array
(
[0] => 4.9
[1] => 3
[2] => Blue
)
[2] => Array
(
[0] => 4.7
[1] => 3.2
[2] => Red
)
[3] => Array
(
[0] => 4.6
[1] => 3.1
[2] => Red
)
[4] => Array
(
[0] => 5
[1] => 3.6
[2] => Red
)
)
You can use explode() on the string, and then use array_chunk() to chunk the array we have from explode function, keep in mind to check for the chunk size
working snippet: https://3v4l.org/qD1t0
<?php
$myString = "5.1,3.5,Red,4.9,3,Blue,4.7,3.2,Red,4.6,3.1,Red,5,3.6,Red"; //and so on
$arr = explode(",", $myString);
$chunks = array_chunk($Arr, 3);
print_r($chunks);
