Note that the PCRE-Modifier "m" is NOT used, so "$" should match the end-of-string only. Test script: --------------- $x = preg_replace('/A.*?$/s', 'X', "A\n"); echo json_encode($x); Expected result: ---------------- "X" Actual result: -------------- "X\n" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79670&edit=1
