I'm trying to get all words from the string. They can include only letters and number. But I completely failed to exclude possible \n, \t etc.

So here is a test string:

word one of each one fish two fish red fish blue fish car : carpet as java : javascript!!&@$%^& testing, 1, 2 testing go Go GO Stop stop hello\nworld hello\tworld hello world \t\tIntroductory Course

I end up with this solution .

But hello\nworld should be hello world hello\tworld should be hello world \t\tIntroductory Course should be Introductory Course

I had also tried solutions with \w \b and \S but I can't make them work as I want too.

How can I ignore/exclude \n and \t?


Pure regex:


PHP (with escaped \):

preg_match_all("/(?:\\\\t|\\\\n)*([A-Za-z0-9]+)/", $str, $matches);

RegEx for Horizontal Whitespace (\s \h \t blank etc), RegEx for Horizontal Whitespace (\s \h \t blank etc) You can also use \h which stands for 'horizontal whitespace', that is, it doesn't match newlines: Match a \h matches horizontal whitespace, which includes the tab and all It is the same as [\n\cK\f\r\x85\x{2028}\x{2029}]. Remove spaces in clipboard. Regex Ignore Space or Whitespace Regex Tab. The tab is a whitespace character which contains multiple spaces. We can maths those contains tabs with the \t like below. "\t" Regex Space In PHP. PHP provides all features of the regular expressions. We can math lines that contain spaces with the preg_match() function like below.

Test here:

Regular Expression Examples, Below, you will find many example patterns that you can use for and adapt to your own RegexBuddy will analyze any regular expression and present it to you in a a space or a tab, you can expand the character class into [ \t\r\n] if you also want to programming language syntax such as comments, strings, numbers, etc. my favorite tool, it can make a diagram of how your regex will work, you can add multiple lines to test if the regex match the strings that you expect and also has a cheatsheet Similar to debuggex except it doesnt generate the diagram, but in my opinion their cheatsheet is cleaner and easier to find what you need.

Match only letters and numbers: \w. Check preg_match_all:

preg_match_all("/\w+/", $str, $matches);

If you are not acutally meaning tabs and newlines (with ascii code 9 and 10), then you can just remove the substrings '\n' and '\t' from the string first:

preg_match_all("/\w+/", str_replace(['\n', '\r'], ' ', $str), $matches);

Regular Expression (Regex) Tutorial, Regex recognizes common escape sequences such as \n for newline, \t for denotes raw strings which ignore escape code, i.e., r'\n' is '\'+'n' >>> re.findall(r'[0-​9]+', match, and # $-[n] and $+[n] for back references $1, $2, etc. print substr($​inStr, The above regex matches two words (without white spaces) separated by​  Excluding Matches With Regular Expressions. Here's an interesting regex problem: I seem to have stumbled upon a puzzle that evidently is not new, but for which no (simple) solution has yet been found. I am trying to find a way to exclude an entire word from a regular expression search.

In addition, a whitespace special character \s will match any

  • Please post the PHP code with a sample string. You must be mistaking string literals for literal strings.
  • Did anything help you?
  • Once I tried preg_match_all pattern it appears to work. Thank you!
  • Thank you for answer, but it doesn't work as I want. It captures all like instead of only words.
  • Yes you are right, I have updated the code, try to use this instead ([^\\nt\!\&\@\$^\s]{1}[a-z0-9]+) I have updated the example in regex link
  • This doesn't solve the issue with tabs and newlines.
  • @falnyr Why not? preg_match_all searches the whole string (whether it includes tabs and newlines or not).
  • It captures the \t and \n characters as words:
  • @falnyr I assume the OP meant a real tab by \t and a real newline by \n.
  • @falnyr If not, he could just remove \n and \t from the string (str_replace())...
