PHP preg_match to find multiple occurrences












9















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";
}

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
