note 113352 added to regexp.reference.meta

Note that if you want to match the dollar character and you are using a double quoted string for defining the pattern, you should use \$ but you need to escape both the backslash and the dollar sign itself. This is because inside a double quoted string PHP will interpret the \$ sequence as a single $ character. Example: To match "$5.00" in "I owe you $5.00 exactly", the "/\$5\.00/" pattern will become "/$5\.00" that it is not the desired pattern. It should be "/\\\$5\.00/" that will become "/\$5\.00/". My recommendation is to always keep this in mind or use single quoted strings, because single quotes has less escape sequences interpreted. ---- Server IP: 69.147.83.199 Probable Submitter: 89.29.181.163 ---- Manual Page -- http://php.net/manual/en/regexp.reference.meta.php Edit -- https://master.php.net/note/edit/113352 Del: integrated -- https://master.php.net/note/delete/113352/integrated Del: useless -- https://master.php.net/note/delete/113352/useless Del: bad code -- https://master.php.net/note/delete/113352/bad+code Del: spam -- https://master.php.net/note/delete/113352/spam Del: non-english -- https://master.php.net/note/delete/113352/non-english Del: in docs -- https://master.php.net/note/delete/113352/in+docs Del: other reasons-- https://master.php.net/note/delete/113352 Reject -- https://master.php.net/note/reject/113352 Search -- https://master.php.net/manage/user-notes.php
