How to find a whole word in a string in PHP without accidental matches?
Solution 1:
You can use a regular expression to easily achive the goal.
Example #2 from the documentation of preg_match:
/* The \b in the pattern indicates a word boundary, so only the distinct
* word "web" is matched, and not a word partial like "webbing" or "cobweb" */
if (preg_match("/\bweb\b/i", "PHP is the web scripting language of choice.")) {
echo "A match was found.";
} else {
echo "A match was not found.";
}
Note that the above example uses the i modifier, which makes the search for "web" case insensitive.
