Question

I have a string that will have pipes | in it.
for example:

$string = 'hello | hello <htmltags> etc|Any character';

NO what i want to do is remove last pipe followed by ANy character.
so that my result would be following after preg_replace.

$replaced_string = 'hello | hello <htmltags> etc';

can you help me, what regular expression pattern i should use.

Answer 1

Then you should replace this

\|[^|]*$

with the empty string

\| matches a |

[^|]*$ matches 0 or more characters that are not a | till the end of the string (because of the $ anchor)

in php it would look like

preg_replace('/\|[^|]*$/', '', $string);

The / around the regex are regex delimiters
