Hack to test --enable-* and --with-* for PHP. This may or may not work, but seems to work. Proof-of-concept. :)

gistfile1.php

<?php
// TODO: Pass in --disable-all? 
// Ideally, pass in all, and disable one at a time (know which caused failure), then log error, remove, try again

$enables = get_all_options('enable');
$withs   = get_all_options('with');

$good = $bad = array();
foreach ($withs as $directive) {

  shell_exec("make clean");
	$out = shell_exec("./configure {$directive['directive']}");
	
	if (strpos($out, "Thank you for using PHP.")) {
		$good[] = $directive;
	} else {
		$bad[]  = $directive;
	}
}

print_r($good);
print_r($bad);

save_information($good, $bad); 

function get_all_options($type = 'enable') {
	
	$out = shell_exec('./configure --help');
	
	preg_match("@Extensions:(.*)Zend:@s", $out, $matches);
	if (empty($matches[1])) {
		return false;
	}
	$out = $matches[1];

	$settings = array();
	foreach (explode(PHP_EOL, $out) as $k => $line) {

		$line = trim($line);
		
		if (0 !== strpos($line, '--' . $type . '-')) {
			continue;
		}
		
		// TODO: Add description
		$setting = preg_replace("@( |=)(.*)$@", "", $line);
		
		$settings[] = array('directive' => $setting, 'description' => '');
	}
	return $settings;
}

function save_information($good, $bad) {
	
	$data = "\n\n========== " . time() . " =========\n";
	$data .= "Good\n";
	foreach ($good as $g) {
		$data .= "$g[directive] ";
	}
	$data .= "\nBad\n";
	foreach ($bad as $b) {
		$data .= "$b[directive] ";
	}
	
	file_put_contents("/tmp/php-config.txt", $data, FILE_APPEND);
	
}

function test_environment() {
	
	// Get version info for stuff like autoconf, gcc, php-src, pwd, ...
	
	// If --help fails, then return false
	$out = shell_exec("./configure --help");

	// If --disable-all fails, then likely return false
	$out = shell_exec("./configure --disable-all");
	
	// If empty configure fails, then maybe fail
	$out = shell_exec("./configure");
	
	// This will likely always fail, but would be great :)
	$out = shell_exec("./configure --enable-all");
