How to extract integer and decimal numbers in PHP string correctly?


How to extract integer and decimal numbers in PHP string correctly?

it helps some times You're using a . for thousands and a , for decimals, and it looks like your text is intended for humans so there will always be a number immediately before a . and ,.
So what you want is 1 or more numbers, followed by 0 or more thousand-groups (a . followed by 3 more numbers), optionally followed by exactly one , and one or more numbers.
code :
One or more numbers: [0-9]+
0 or more thousand-groups: (\.[0-9]{3})*
Optionally a `,` and one or more numbers: (,[0-9]+)?
$string = 'María vive en un pueblo de 25 957 habitantes y cobra 1859 euros al mes. OJO: no sé si os habéis fijado, pero los números del último ejemplo 
no llevan un punto o una coma separando los millares (25.957 o 1.859). Sé que resulta extraño, pero la nueva normativa de la R.A.E. 
dice que los números de cuatro cifras NO llevarán separación (1859) y los números de cinco cifras o más NO llevarán ni puntos ni comas, 
sino una separación (25 957 o 1 343 392). El 94% de los niños ha traído los deberes hechos. He pagado $50,95 dólares.';

$matches = [];
preg_match_all('/[0-9]+(\.[0-9]{3})*(,[0-9]+)?/', $string, $matches);

print_r($matches[0]);

/*
Array
(
    [0] => 25
    [1] => 957
    [2] => 1859
    [3] => 25.957
    [4] => 1.859
    [5] => 1859
    [6] => 25
    [7] => 957
    [8] => 1
    [9] => 343
    [10] => 392
    [11] => 94
    [12] => 50,95
)
*/

this one helps. Eg: , This should do it:
code :
<?php
    $str = '';
    $str .= "Additional tax(2.34)";
    $str .= "Additional tax(3)";

    if (preg_match_all('/\((\d+(?:\.\d+)?)\)/', $str, $matches) > 0) {
        var_dump($matches[1]);
    }
?>

I wish did fix the issue. Assuming your data is consistent, this should work fine, and has the added advantage of being easier on the eyes. Also consider decimal if you're going for precision.
code :
select
  cast(left(r, charindex('%', r) - 1) AS float) as minVal,
  cast(replace(right(r, charindex('-', r) - 1), '%', '') as float) AS maxVal
from ( select '22.45% - 42.32%' as r ) as tableStub

I wish this helpful for you I have an Excel file that contains roughly 40,000 rows of data and i am trying to create a new columnn of only the number and decimal portion of a strinng in another column. I tried to TRIM() and LEFT() but the number value size effects that extraction. I also saw another post in StOv that extracts numbers only but my goal is to grab the decimals so I can see the exact value. Here is an example of the content of one cell. for any help!!! , With data in A1, use:
code :
=MID(A1,FIND("(",A1)+1,FIND(")",A1)-FIND("(",A1)-1)

this will help I've been trying to extract decimal numbers from strings in sparklyr, but it does not work with the regular syntax you would normally use outside of Spark. , You could use regexpr from base R
code :
v <- "$170.5M"
regmatches(v, regexpr("\\d*\\.\\d", v))
# [1] "170.5"
