How to declare a RegEx with character repetition to match the strings "http", "htttp", "httttp", etc in PHP

Answer 1

// Declare the regex pattern
$pattern = "/^htt+p$/";

// Test strings
$testStrings = ["http", "htttp", "httttp", "httpp", "htp"];

// Check matches
foreach ($testStrings as $test) {
    $match = preg_match($pattern, $test);
    echo "Matches \"$test\": " . ($match ? "true" : "false") . "\n";
}

// Matches "httpp": True or false, depending on how matches() method works


/*
run:

Matches "http": true
Matches "htttp": true
Matches "httttp": true
Matches "httpp": false
Matches "htp": false

*/
