Regex match string that ends with number

Question

What is a regex to match a string that ends with a number for example

"c1234" - match
"c12" - match
"c" - no match

Tried this but it doesn't work

(?|c(?|[0-9]*$))

Thanks again,

The beggining string needs to be specific too

Solution 1

Just use

\d$

to check your string ends with a digit

If you want your string to be a "c" followed by some digits, use

c\d+$

Solution 2

You can use this regular expression pattern

^c[0-9]+$

Solution 3

To match any string ending with a digit use: [\s\S]*\d$

if (preg_match('/[\s\S]*\d$/', $value)) {
   #match
} else {
  #no match
}
