preg_match(): Text range out of order on PHP Regex

Question

I want to convert java regex to php regex. But I get error "- Text range out of order"

This is JAVA regex

"[^\\u0020-\\u007F\u011f\u00fc\u015f\u00f6\u00e7\u011e\u00dc\u015e\u0130\u00d6\u00c7\u0131]";

This is PHP regex

preg_replace("/[^\\x{0020}-\\x{007F}\\x{011f}\\x{00fc}\\x{015f}\\x{00f6}\\x{00e7}\\x{011e}\\x{00dc}\\x{015e}\\x{0130}\\x{00d6}\\x{00c7}\\x{0131}]/i","",".çşüiğıyuasdfaadsff");

I get following error "- Text range out of order"

Any Help?

Where do you get this error? When pasting the regex string into regex101.com? — Wiktor Stribiżew

Not sure why you get that error: On ideone, I get this PHP Warning: preg_replace(): Compilation failed: character value in \x{} or \o{} is too large at offset 26 in /home/ivJ7iQ/prog.php on line 3 ideone.com/lbZv74 — nhahtdh

By default, the regex engine interprets the input string and the regex as an array of bytes in PHP. You should get an error about the character value too large, since \x{011f} or \x{011e} are larger than 255 (the maximum value of one byte).

To match Unicode code points, rather than arbitrary byte sequences, use u flag to turn on UTF mode.

$re = '~[^\x{0020}-\x{007F}\x{011f}\x{00fc}\x{015f}\x{00f6}\x{00e7}\x{011e}\x{00dc}\x{015e}\x{0130}\x{00d6}\x{00c7}\x{0131}]~u';
