使用php从字符串的开头修剪所有开始的整数

Question

here is my column title

132 lorem ipsum...
21-2 gold sky...
325/1 blue river...
420 health and food
right decision
... and so on.

So many titles begins with various integers and sometimes the integer is divided by / or -;

How can I trim all of them and get only alphabet part, i.e.:

lorem ipsum...
gold sky...
blue river...
health and food
right decision

Thanks.

Answer 1

We can try using preg_replace here to remove initials numbers, forward slash, or dash, followed by optional whitespace:

$input = "132 lorem ipsum...
21-2 gold sky...
325/1 blue river...
100 420 health and food
right decision";
$output = preg_replace("/(?<=^|
)[0-9\/ -]+/", "", $input);
echo $output;

lorem ipsum...
gold sky...
blue river...
health and food
right decision

Demo

Note this answer is robust to a line having more than one term containing numbers, e.g. 100 420 health and food becomes health and food.
