How to present print_r()'s array output on one line (with no newlines)

How would I print the following in one line?

$product_array = array(
    "id" => 001,
    "description" => "phones",
    "type" => "iphone"
);

print "Print the product_array = ";
print_r($product_array);

Current result

Print the product_array =Array
(
[id] => 001 
[description] => phones 
[type] => iphone 
)

Wanted Result

Print the product_array =Array ( [id] => 001 [description] => phones [type] => iphone )

just added some styleing:

echo ltrim(rtrim(str_replace(["\n",'Array(', "[", "]", " => "], ['','', " / <span style='color: #0060df'>", "</span>", ": "], print_r($2d_array, true)), ")"), "/ ")

This is what I use:

$width = 150;
$height = 100;

print json_encode(compact('width')) . PHP_EOL;
print json_encode(compact('height')) . PHP_EOL;

The output is:

{"width":369}
{"height":245}

The added benefit is that you can do multiple variables into the compact function at once:

print json_encode(compact(['width', 'height'])) . PHP_EOL;

The output in this case is:

{"width":369,"height":245}

Note that it is possible to replace several different chars (for example line break and null) at the same time, e.g.:

echo str_replace(array("\n", "\0"), "", print_r($product_array, 1))

If you're just looking to view the contents of the array for monitoring or debugging purposes, perhaps encoding the array as a JSON would be useful:

print "Print the product_array = " . json_encode($product_array);

Result:

Print the product_array = {"id":1,"description":"phones","type":"iphone"}

Alternatively, you could use the var_export function to get a parsable representation of the variable and then simply remove all the new line characters in the string.

var_export — Outputs or returns a parsable string representation of a variable

Here is a simple example:

$str = var_export($product_array, true);
print "Print the product_array = " .  str_replace(PHP_EOL, '', $str);

This will give you exactly the result you specified:

Print the product_array = array ( 'id' => 1, 'description' => 'phones', 'type' => 'iphone',)

I would recommend the first option since it requires less "manipulation" of the strings - the second option starts to perform replacements where as the first simply provides a readable output right away.

$arrayString = print_r($array, true);
echo str_replace("\n", "", $arrayString);

The second value of print_r lets the function return the value instead of printing it out directly.

echo str_replace("\n", '', print_r($product_array, true));
