Warning: preg_replace(): Unknown modifier 'g'
I got an error by this regular expression...
$strTmp = preg_replace('~(<\/CharacterStyleRange>(.*?)\n*</CharacterStyleRange>)~gim ' , "</CharacterStyleRange>", $strTmp);
Error
Warning: preg_replace(): Unknown modifier 'g' in ....
Why?
Solution 1:
g
is implicit with preg_replace()
. You don't need to include it.
Solution 2:
You don't have to specify the global flag. From the documentation, there is a separate parameter ($limit
) used to specify the number of replacements to make:
limit The maximum possible replacements for each pattern in each subject string. Defaults to -1 (no limit).
So, unless you specify a positive number for this parameter, it will replace all occurrences by default:
$strTmp = preg_replace('~(<\/CharacterStyleRange>(.*?)\n*</CharacterStyleRange>)~im ' , "</CharacterStyleRange>", $strTmp);
