regex - Php: how could I remove any character, or whole string from a string, excluding the ones between quotes? -


this thread similar, dont want remove white spaces, characters. example, im trying remove new lines (0x10 or 0x13 characters) string, if around ' ' or " " must remained untouched. im using php.

you replacing following expression:

("[^"]*"|'[^']*')|[\r\n]+

with content of first capturing group: $1.

this works capturing quote , replacing self, or matching things want remove, , replacing them empty string.

if want handle backslash escapes too, use following expression instead in same replacement:

("(?:[^"\\]+|\\.)*"|'(?:[^'\\]+|\\.)*')|[\r\n]+
