how to return a numeric value from string in php?
Do you want to extract it from a string or the string is a number itself?
# case 1 $str1 = "Buy 12 apples, 1.5kg of beans and 4 onions, it's already 12:35 hurry up, it's l4t3!"; # case 2 $str2 = '12';
In first case by using
preg_match_all() with a simple pattern like this
/[\d]+/ you get:
Array (  => Array (  => 12  => 1  => 5  => 4  => 12  => 35  => 4  => 3 ) )
it will just scan for digits, it's not searching for floats or dates or time and will include the numbers in the word
l4t3 (i.e. late), docs:
In the second case use type hint:
$a = (int) $str2; # or $b = intval($str2);
which works for integers. You will need
floatval() to get decimals. Docs:
Note: please, next time use an appropriate title.
