Separate string with explode php - php

Question

I am using explode in PHP, because I need to separate a string. of this type:
$Data = '10 x 4';
I need to separate the numbers because then I do a math operation on them . The code I have works well when they are integers. If I have a string of this type 10 x 2.5 it does not take into account the decimal part that would be the , 5. How can I do to make me take this part into account too?
$data = '10 x 2,5';
$array = explode("x", $data);
$total = $array[0]*$array[1];

Answer 1

Here are two approaches you could take. If you can change the comma separator to a period/full stop:
$data = '10 x 2.5';
$floats = array_map('floatval', explode(' x ', $data));
echo $floats[0] * $floats[1];

or you could use a regex which also will confirm you have the right data format.
echo preg_replace_callback('/(\d+(?:[.,]\d+)?)\h*x\h*(\d+(?:[.,]\d+)?)/', function($match) {
return str_replace(',' , '.', $match[1]) * str_replace(',' , '.', $match[2]);
}, $data);

Answer 2

Try with this. Just replace "," with "." and it's working.
$data = '10 x 2,5';
$data = str_replace(',','.','10 x 2,5');
$array = explode("x", $data);
echo $total = $array[0]*$array[1];

Answer 3

try this:
<?php
$data = '10 x 2,5';
$array = explode("x", $data);
$total = floatval(str_replace(',', '.', $array[0]))*floatval(str_replace(',', '.', $array[1]));
?>
here str_replace() is used to check if there are ,
in the string and then convert into its float value.
Hope this helps.

Answer 4

$data = '10 x 2,5';
$array = explode("x", $data);
$decimal =$array[1];
//replace the comma with dot
$decimal_formated = str_replace(',', '.', $decimal);
//format the string to float
$decimal_formated = (float)$decimal_formated;
//OR $decimal_formated = floatval($decimal_formated);
//get total
$total = $array[0]*$decimal_formated;
//french format $total, with comma
$total_with_comma =number_format($total, 1, ',', ' ');
echo $decimal.'</br>'; //output 2,5
echo $decimal_formated.'</br>'; //output 2.5
echo $total.'</br>'; //output 25
echo $total_with_comma.'</br>'; // output 25,0
You can use number_format(), floatval().
