Remove Non-Numeric Characters (Excluding Periods and Commas) from a String (I.E. Remove All Characters Except Numbers, Commas, and Periods)

Remove non-numeric characters (excluding periods and commas) from a string (i.e. remove all characters except numbers, commas, and periods)

You could use preg_replace to swap out all non-numeric characters and the comma and period/full stop as follows:

$testString = '12.322,11T';
echo preg_replace('/[^0-9,.]+/', '', $testString);

The pattern can also be expressed as /[^\d,.]+/

PHP - remove all non-numeric characters from a string

You can use preg_replace in this case;

$res = preg_replace("/[^0-9]/", "", "Every 6 Months" );

$res return 6 in this case.

If want also to include decimal separator or thousand separator check this example:

$res = preg_replace("/[^0-9.]/", "", "$ 123.099");

$res returns "123.099" in this case

Include period as decimal separator or thousand separator: "/[^0-9.]/"

Include coma as decimal separator or thousand separator: "/[^0-9,]/"

Include period and coma as decimal separator and thousand separator: "/[^0-9,.]/"

How to remove all non numeric characters (excluding minus, dot and comma) in a string in Javascript?

To remove all chars but digits, commas, dots and a hyphen at the start of the string, you may use

text = text.replace(/^(-)|[^0-9.,]+/g, '$1');

See the regex demo

Details

• ^(-) - start of string and a - captured into Group 1
• | - or
• [^0-9.,]+ - any 1+ chars other than digits, . and ,.

The replacement is $1, i.e. if there was a leading - it will remain in the result.

A bit more comprehensive regex that only keeps the last non-final comma/dot is

text = text.replace(/^(-)|[.,](?=[^.,]*[.,](?!$))|[,.]+$|[^0-9.,]+/g, '$1');

See this regex demo

Here, some more alternatives are added:

• [.,](?=[^.,]*[.,](?!$)) - matches . or , that are followed with another . or , somewhere after 0+ chars other than . and ,
• [,.]+$ - matches any 1+ trailing commas/dots.

Get Number only without any text

Get all the numbers before 'Indonesische roepia' with a regex:

/([0-9.,]+)\ Indonesische roepia/

<?php

$url ='https://www.google.com/search?q=1+usd+to+idr';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, FALSE);
curl_setopt($curl, CURLOPT_HEADER, FALSE);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
$curl_response = curl_exec($curl);
curl_close($curl);
if(!preg_match_all("/<div[^>]*class=\"\s*BNeawe\s+iBp4i\s+AP7Wnd\s*\"[^>]*>(.*?)<\/div>/s", $curl_response, $result, PREG_SET_ORDER)){
   echo 'Invalid output';
   exit;
}

$re = '/([0-9.,]+)\ Indonesische roepia/';
preg_match($re, $result[0][1], $number);
echo '<pre>';
print_r((float) $number[1]);
echo '</pre>';

<pre>14.391</pre>

Strip all non-numeric characters from string in JavaScript

Use the string's .replace method with a regex of \D, which is a shorthand character class that matches all non-digits:

myString = myString.replace(/\D/g,'');

Java String remove all non numeric characters but keep the decimal separator

Try this code:

String str = "a12.334tyz.78x";
str = str.replaceAll("[^\\d.]", "");

Now str will contain "12.334.78".

Removing (nearly) all non-numeric characters from a string

If I understand you correctly you can use this:

$re = "/[0-9XxTtEe+:]*/"; 
$str = "394160etg9834ztg";  // <-- User Input

preg_match_all($re, $str, $matches);

In $matches should be all characters that are allowed. Just combine the results that are matched in $matches

Preg_replace all but digits and . and ,

Use [^0-9\.,] as your matching expression.
