Function ereg() is deprecated

由 六月ゝ 毕业季﹏ 提交于 2020-01-10 05:48:10
问题 I'm going through my code to replace any instances I'm using the ereg() function - which I was using for matching regex inside a string. I could use a little direction, if someone has a better method than what I'm using. Here's my old "currency validation" script: function valid_currency($number){ if(ereg('^[0-9]+\.[0-9]{2}$', $number)) return true; else return false; } if(valid_currency(25.30)){ echo "valid currency"; }else{ echo "invalid currency string"; } I replaced the ereg() with preg

Validate time format using preg_match

由 拜拜、爱过 提交于 2020-01-09 11:27:11
问题 I want to validate a time input (like 10:30 am, 02:30 pm) using preg_match() I use this, $pattern = "/([1-12]):([0-5])([0-9])( )(am|pm|AM|PM)/"; if(preg_match($pattern,$time)){ return true; } But when i give an input like 10:30 pmxxxx it will not validated. I dont know whether the method is correct or not. Help please. 回答1: The [...] notation in regexes defines character class: something that's applied to the single character. It's alternation that should be used here instead: 0[1-9]|1[0-2] .

Regular Expression to match dates in YYYY-MM-DD format

由 允我心安 提交于 2020-01-07 06:56:58
问题 I have a regular expression in PHP that looks for the date in the format of YYYY-MM-DD What I have is: [\d]{4}-[\d]{2}-[\d]{2} I'm using preg_match to test the date, the problem is that 2009-11-10 works, but 2009-11-1033434 works as well. It's been awhile since I've done regex, how do I ensure that it stops at the correct spot? I've tried doing /([\d]{4}-[\d]{2}-[\d]{2}){1}/ , but it returns the same result. Any help would be greatly appreciated. 回答1: What you need is anchors, specifically ^
