Remove all non-numeric characters from a string in PHP
I'm trying to remove all non-numeric characters from a string.
This is the string:
$price = '₪1,180.00';
(the first character is the new israeli shekel currency symbol)
I tried to use:
$price_numeric_value = preg_replace( '/D/', '', $price );
echo '<pre>';var_dump( $price_numeric_value );echo '</pre>';
$price_numeric_value = preg_replace( '~D~', '', $price );
echo '<pre>';var_dump( $price_numeric_value );echo '</pre>';
$price_numeric_value = preg_replace( '/[^0-9.]/', '', $price );
echo '<pre>';var_dump( $price_numeric_value );echo '</pre>';
As suggested in these posts:
https://stackoverflow.com/a/34399544/4711865
https://stackoverflow.com/a/33993704/4711865
The output i'm getting is this:
string(10) "8362118000"
Any idea why?
EDIT: I'm running this code on a Wordpress website, the php file is encoded in utf-8 and adding header('Content-Type: text/html; charset=utf-8'); doesn't help.

Check the UTF8 encoding of the files. Trypreg_replace( '/D+/u', '', $price );, too.

@WiktorStribiżew Yes! I literally place them one below the other... that's the reason I posted this, somehow the value is being mixed up!

8362 is the numeric part of the html entity for the New Sheqel Sign ₪, when you remove all non numeric you got 8362 just before the value.
You have to decode the string before preg_replace.
$price_numeric_value = preg_replace( '/D/', '', html_entity_decode($price) );
echo $price_numeric_value;
