strpos

问题 How can i define multiple needles and still perform the same actions below. Im trying to define extra keywords such as numbers, numerals, etc... as of now i have to create a duplicate if loop with the minor keyword change. if (stripos($data, 'digits') !== false) { $arr = explode('+', $data); for ($i = 1; $i < count($arr); $i += 2) { $arr[$i] = preg_replace('/\d/', '', $arr[$i]); } $data = implode('+', $arr); } 回答1: Create a function that loops through an array? function check_matches ($data,

问题 $domains = file('../../domains.txt'); $keywords = file('../../keywords.txt'); $domains will be in format of: 3kool4u.com,9/29/2013 12:00:00 AM,AUC 3liftdr.com,9/29/2013 12:00:00 AM,AUC 3lionmedia.com,9/29/2013 12:00:00 AM,AUC 3mdprod.com,9/29/2013 12:00:00 AM,AUC 3mdproductions.com,9/29/2013 12:00:00 AM,AUC keywords will be in format of: keyword1 keyword2 keyword3 I guess I would really like to do an array for keywords from a file and search each line of domains.txt for matches. Not sure

问题 This is my code, and when I run this function I get this : Warning: array_push() expects parameter 1 to be array However I define $printed as an array prior to starting. $printed = array(); function dayAdvance ($startDay, $endDay, $weekType){ $newdateform = array( 'title' => date("M d", strtotime($startDay))." to ".date("M d", strtotime($endDay)). $type, 'start' => $startDay."T08:00:00Z", 'end' => $startDay."T16:00:00Z", 'url' => "http://aliahealthcareer.com/calendar/".$_GET['fetching']."/".

问题 Huh, looking at all those string functions, sometimes I get confused. One is using all the time mb_ functions, the other - plain ones, so the question is simple... When should I use mb_strpos(); and when should I go with the plain one ( strpos(); )? And, yes, I'm aware about that mb_ functions stand for multi-byte, but does it really mean, that if I'm working with only utf-8 encoded strings, I should stick with mb_ functions? Thanks in advance! 回答1: You should use the mb_ functions whenever

问题 Say I have a long UTF-8 encoded string. And say I want to detect if $var exists in this string. Assuming $var is always going to be simple letters or numbers of ascii characters (e.g. "hello123" ) I shouldn't need to use mb_strpos or iconv_strpos right? Because it doesn't matter if the position is not character-wise correct as long as its consistent with the other functions. Example: $var='hello123'; $pos=strpos($utf8string,$var); if ($pos!==false) $uptohere=substr($ut8string,0,$pos); Am I

问题 I have this code here: $imagePreFix = substr($fileinfo['basename'], strpos($fileinfo['basename'], "_") +1); this gets me everything after the underscore, but I am looking to get everything before the underscore, how would I adjust this code to get everything before the underscore? $fileinfo['basename'] is equal to 'feature_00' Thanks 回答1: You should simple use: $imagePreFix = substr($fileinfo['basename'], 0, strpos($fileinfo['basename'], "_")); I don't see any reason to use explode and create

问题 I am wondering how to complete multiple strpos checks. Let me clarify: I want strpos to check the variable "COLOR" to see if any numbers from 1 to 8 are anywhere in the variable. If any numbers from 1 to 8 are present, I want to echo "selected". Examples: Let's say only the number 1 is in the variable, it will echo "selected". Let's say the numbers 1 2 and 3 are in the variable, it will echo "selected." Let's say the numbers 3 9 25 are in the variable, it will echo "selected" (because of that
