kts Posted January 23, 2009 Share Posted January 23, 2009 Hi, I'm trying to cut a string. I have anywhere from 1 to 10 #s then " - " then item name. I am trying to just cut the number from the beginning. I was using the trim functions and such, but it is a very bad practice. I was told you can accomplish this mostly error free in regex? I tried [0-9], but it only grabbed one digit. Link to comment https://forums.phpfreaks.com/topic/142113-solved-new-to-regex/ Share on other sites More sharing options...
gevans Posted January 23, 2009 Share Posted January 23, 2009 [0-9] will match any single integer [0-9]{10} will match any 10 integers ^[0-9]{10} will match any 10 integers fron the start Link to comment https://forums.phpfreaks.com/topic/142113-solved-new-to-regex/#findComment-744317 Share on other sites More sharing options...

.josh Posted January 23, 2009 Share Posted January 23, 2009 you need to give some actual example formats. Are there spaces between the hyphen? anything else on the line? etc..

kts Posted January 23, 2009 Author Share Posted January 23, 2009 it has space after the id and then a hyphen as well as another space after. from testing it seems if I grab the numbers from start /^[0-9]{1,}/ seems to be working fine, but someone mentioned /d+?

.josh Posted January 23, 2009 Share Posted January 23, 2009 fyi {1,} is the same as doing + and \d is mostly the same as doing [0-9] (it also includes exponents) Link to comment https://forums.phpfreaks.com/topic/142113-solved-new-to-regex/#findComment-744341 Share on other sites More sharing options...
