PHP preg_match to find multiple occurrences

php, preg-match

Solution

You want to use `preg_match_all()`. Here is how it would look in your code. The actual function returns the count of items found, but the `$matches` array will hold the results:

<?php
$string = "/brown fox jumped [0-9]/";

$paragraph = "The brown fox jumped 1 time over the fence. The green fox did not. Then the brown fox jumped 2 times over the fence";

if (preg_match_all($string, $paragraph, $matches)) {
  echo count($matches[0]) . " matches found";
}else {
  echo "match NOT found";
}
?>

Will output:

2 matches found

Problem

What is the correct syntax for a regular expression to find multiple occurrences of the same string with preg_match in PHP? For example find if the following string occurs TWICE in the following paragraph: ``` $string = "/brown fox jumped [0-9]/"; $paragraph = "The brown fox jumped 1 time over the fence. The green fox did not. Then the brown fox jumped 2 times over the fence" if (preg_match($string, $paragraph)) { echo "match found"; }else { echo "match NOT found"; } ```
