PHP function to build query string from array - not http build query - php

Question

Hello I know all about http://www.php.net/manual/en/function.http-build-query.php to do this however I have a little problem.
It "handly" turns boolean values into ones and zeros for me. I am building a little PHP wrapper for the Stack Overflow api and parsing an option array and then sending this onto the api breaks things..(doesn't like 1 for true).
What I would like is a simple function to turn a single dimensional array into a query string but turning true/false into string values of true/false.
Anyone know of anything that can do this before I start re-inventing the wheel

Answer 1

I don't know of anything offhand. What I'd recommend is first iterating through the array and covert booleans to strings, then call http_build_query
E.g.
foreach($options_array as $key=>$value) :
if(is_bool($value) ){
$options_array[$key] = ($value) ? 'true' : 'false';
}
endforeach;
$options_string=http_build_query($options_array);

Answer 2

Try passing http_build_query true and false as strings instead of booleans. You may get different results.

Answer 3

If you just need to convert your true/false to "true"/"false":
function aw_tostring (&$value,&$key) {
if ($value === true) {
$value = 'true';
}
else if ($value === false) {
$value = 'false';
}
}
array_walk($http_query,'aw_tostring');
// ... follow with your http_build_query() call

Answer 4

Loop through each variable of the query string ($qs) and if bool true or false, then change value to string.
foreach($qs as $key=>$q) {
if($q === true) $qs[$key] = 'true';
elseif($q === false) $qs[$key] = 'false';
}
Then you can use the http_build_query()

Answer 5

have a look at my wheel:
function buildSoQuery(array $array) {
$parts = array();
foreach ($array as $key => $value) {
$parts[] = urlencode($key).'='.(is_bool($value)?($value?'true':'false'):urlencode($value));
}
return implode('&', $parts);
}
