Let's say I have a strings:
a) 'one4two2three1'
b) 'one4two2three1four#five7'
I want to replace all numbers from these strings with empty space ('') - untill '#' character
so final output should be:
a) 'onetwothree'
b) 'onetwothreefour#five7'
Is there a way to do it with preg_replace(), or any other regex function?
I'm trying to avoid an 'if' with strpos() and substr() and find more efficient way
You can use PCRE verbs (*SKIP)(*F)
to match and discard part after #
:
$repl = preg_replace('/#[^#]*$(*SKIP)(*F)|\d+/m', '', $str);
#[^#]*$(*SKIP)(*F)
will match and skip part after #
in input and then we can replace all digits by empty string.
