I have a number like that : 342.50 EUR. How to table only the number : 342.50 I tried this, but it's not the result that I want
$str = '342.50 EUR';
preg_match_all('!\d+!', $str, $matches);
print_r($matches);
result : Array ( [0] => Array ( [0] => 342 [1] => 00 ) )
It's as simple as this ...
$str = +'342.50 EUR';
or
$str = '342.50 EUR';
$str = +$str;
This way, no need to know about the type of number (int or float).
This is a compact version of 0 + '342.50 EUR'. PHP will cast the string to the first number part it can find in it. If no number is there, then it will result to zero.
You could cast it to a float :
$str = '342.50 EUR';
$float = floatval($str);
And after, you can chose the number of decimals to show with number_format :
echo(number_format($float, 2));
You can do this in two steps:
These steps can be performed in these lines:
$string = '342.50 EUR';
$string = str_replace(" EUR", "", $string);
$float_value_of_string = floatval($string);
echo $float_value_of_string; //342.50
