Export all data from the Consul KV store into consul kv put commands

consul-kv-export.php

<?php

$output = shell_exec('consul kv export');

if (null === $output) {
    echo 'Could not run `consul kv export`. Is consul installed?' . PHP_EOL;
    exit(1);
}

$data = json_decode($output, true);

foreach ($data as $item) {
    $value = base64_decode($item['value']);

    // Skip items with empty values
    if ('' === $value) {
        // Optional output to remove these keys
        // echo 'consul kv delete ' . $item['key'] . ' ' . $value . PHP_EOL;
        continue;
    }

    // Quote values containing special characters
    if ($value !== htmlspecialchars($value)) {
        $value = '"' . $value . '"';
    }

    echo 'consul kv put ' . $item['key'] . ' ' . $value . PHP_EOL;
}

exit(0);

that'll need addslashes() or something around $value - line 24

good work Ollie, this is amazing

issue:

# consul kv delete --recurse
Success! Deleted keys with prefix:
# consul kv put test_key1 test_value1
Success! Data written to: test_key1
# consul kv put test_key2 "test value 2"
Success! Data written to: test_key2
# php consul-kv-export.php
consul kv put test_key1 test_value1
consul kv put test_key2 test value 2
