currently i am using php preg_replace to replace certain portion of string
12854827.12854827_IDS.0 12854827.12854827_892.0
12854827.12854827_IDS.0 12854827.12854827_892.0
here i required output is
12854827.IDS.0 12854827.892.0
12854827.IDS.0 12854827.892.0
but preg_replace produced output
12854827.892.0
12854827.892.0
php code that i used given below
preg_replace('/\..*_/', '.', $A)
how i solve above problem ? & how i replace nearest matching word using php preg_replace ?
Use the following regular expression to capture everything between a dot character (.) and an underscore (_):
/\.([^_.]+)_/
Breakdown:
/ - starting delimiter
\. - match literal dot (.) character[^_.] - character class that matches any character that's not a . or _ one or more times_ - match literal underscore (_) character/ - ending delimiterThe preg_replace() statement should look like:
preg_replace('/\.([^_.]+)_/', '.', $A);
Effectively, it says: "Replace everything between a . and _ with a .".
Output:
12854827.IDS.0 12854827.892.0
12854827.IDS.0 12854827.892.0
. and _. See Regex101 demoSince you are using digit replace you can use this one:
preg_replace('/\.\d+_/', '.', $A);
