Convert an array to string using PHP [duplicate]

Question

Still new in PHP and I am trying to convert an array to string in my code below:

$totalProfitsArray = print_r($profits['totalProfit']);

If I echo the $totalProfitsArray variable above i get this result:

Array ( [0] => Array ( [count] => 44.35 ) )

which is fine but i want to echo only the 44.35 value. So i tried to use the implode method like this:

implode("", $totalProfitsArray);

but still didn't work and i get this error:

implode(): Invalid arguments passed

What I am doing wrong? Is there any other easy way to convert the array in string and print the result?

If you var_export your original $profits array, it makes it easier for others to understand your data structure and consume/work with the data. — Progrock

The return of print_r will likely be true, so your assignment above to an array is misguided. — Progrock

If you want an array as a string to be used reused later by PHP then consider using the built-in serialize() and unserialize() functions. .... php.net/manual/en/function.serialize.php — GetSet

On print_r() always returns true unless the 2nd parameter is specified as true, in which print_r() will return a string of it's results as opposed to echoing the contents. .... php.net/manual/en/function.print-r.php — GetSet

you are getting value in another array like this

$arr = array(array('count' => 44.35));

to get the inner value you have to access it like this:

print_r($profits['totalProfit'][0]['count']); $totalProfitsArray = $profits['totalProfit'][0]['count'];

You probably don't want to assign to a print_r (with the exception of the second argument). Here the print_r is unnecessary. Targeting the count index of the zeroth element of the array should be enough.

No worries! i already removed the print_r and works just fine.
