PHP Simple array to string conversion

Question

This is driving me crazy and definitely fits into some sort of stupid question category, but for some reason my minds gone completely blank. I KNOW there is a simple way to do this, a default PHP function even, but I can't find it.

If anyone can help, there's some easy points for you.

I have an array like this:

array(
    'oauth_consumer_key'        =>  "mykey",
    'oauth_signature'           =>  "mysignature",
    'oauth_signature_method'    =>  "HMAC-SHA1",
    'oauth_timestamp'           =>  1452103343
);

I want to turn it into this:

echo someFunction($data);
// returns
// 'oauth_consumer_key="mykey", oauth_signature="mysignature", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1452103343"'

Can anyone point me in the right direction?

You can use array_map() to loop through keys and values at once, and make an array with "key => value" elements, which you then can implode() into a comma separated list; If you get stuck, post the attempt here. — Rizier123

Is there not a built in function similar to http_build_query? I'm sure there is a simpler way, unless i'm going mad — John Mellor

PHP doesn't provide you: build_me_a_yellow_pink_striped_house() function, but it does give you a hammer(), screwdriver(), ... — Rizier123

There are multiple functions you could try.

array_map() is one of them. You can use this function with a combination of something like implode() to get what you want but it is a little complicated since your mind has gone blank haha.
print_r() will print out your array with keys and values. Simple to use.
var_dump() same behavior as print_r() except it will give you key and value types as well.
Or you could use json_encode() which will return you as string as you say you want.

Try the built-in PHP function print_r. It will pretty-print the array for you.

Or, if you want an in-memory variable, you can do something like:

function array_to_string($array) {
    $acc = "";
    foreach($array as $key => $value) {
        $acc = $acc.$key.'='.$value.', ';
    }
    return substr($acc, 0 -1);
}

Yes its very simple you can use like that

function yourrequirement($yourArr){
    foreach($yourArr as $key => $value){
         echo " ' " .$key. "  = ".'"'.$value.'",'."'";
    }
}

//Call your function
yourrequirement($yourArr);
