Regex find word inside string
I've tried ^name& but it does not work. How can I find a 开发者_开发问答name inside hello-my-name-is
/.name./ The two points indicate, that there is at least one character on each side.
I think what you're looking for is either /name/ or /\bname\b/. \b is an indicator for word boundary. See this doc for more info: http://www.regular-expressions.info/wordboundaries.html
The reason ^name$ doesn't give you any results when searching the string "hello-my-name-is" is because the character ^ anchors the search to the start of the string. Similarly $ anchors the search to the end. For example:
^nameworks only if the string started with"name"e.g."name is cool"name$works only if the string ended with"name"e.g."where is name"
For more info about anchors see this page: http://www.regular-expressions.info/anchors.html
/name/ seems to work well here.
$str = "hello-my-name-is";
$str1 = preg_match("/name/", $str);
echo $str . " => " . $str1;
The output is -
hello-my-name-is => 1
Means it found the name subsctring, and it appeared 1 time.
