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";

}





php preg-match

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

Origin of the phrase “under your belt”?

Image
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0; } 17 1 Today, I found myself discussing what students should have "under their belts" during a lecture, and I wondered to myself if there was some inappropriate undertone here that I might be unaware of. Question : What is the origin of the phrase "under your belt"? A google search revealed some webpages (e.g. [1]) that assert its origin is related to consumption of food -- once a meal has been eaten, it's under your belt (which is a relief). However, with such websites, I have no way to determine fact from "random guy on the internet making stuff up". etymology idioms ...
