Little php script to install the same couch app on a bunch of dbs in the same instance

couchapp_mass_installer.php

<?php
	// Configure control variables
	$couch_url = "http://yourcouchinstance.com";
	$path_to_couchapp = "/local_path_to/couchapp/";
	
	// Counter
	$db_count = 0;
	
	// Time check (we'll use this later)
	$start_ts = time();

	// Get all the dbs
	$all_dbs_str = `curl -X GET {$couch_url}/_all_dbs`;
	$all_dbs = explode('","', trim(str_replace(array('["','"]'), '', $all_dbs_str)));
	
	// Loop through the dbs, injecting the app into each one
	foreach($all_dbs as $db) {
		// Only copy the ones with the "phl_" prefix
		if(strpos($db, 'phl_') !== false) {
			$db = trim($db);	// Extra cleaning
			echo "Pushing couchapp to {$db}\n";
			echo `couchapp push {$path_to_couchapp} {$couch_url}/{$db}`;
			echo "\n";
			$db_counter++;
		}
	}
	
	// Final time check
	$end_ts = time();
	
	// Figure time spent
	$run_time = $end_ts - $start_ts;
	
	// Print out summary
	echo "====================\n";
	echo 'Run finished in ' . $run_time .' seconds.' . "\n";
	echo $db_counter . ' databases replicated.' . "\n";
