php str_replace casting integer to scientific number

I do have issues with str_replace on my webserver casting intergers to scientific number notation.

$strContent = "Yesterday was ##yesterdayTimestamp##!";
$yesterDayTimestamp = floor((time() - (24 * 3600)) / (24 * 3600)) * 24 * 3600 * 1000 ;
$strContent = str_replace("##yesterdayTimestamp##", $yesterDayTimestamp, $strContent) ;

echo $strContent;

// expected output / result on local server
// "Yesterday was 1423612800000!"

// result on remote production server
// "Yesterday was 1.4236128E+12!"

Trying to solve the problem with str() or format_number() seem not to work

How can I prevent php from using the scientific notation in code?

I found a solution to the question by changing the php configuration e.g.: PHP Scientific Notation Shortening. However since I'm in an hosted environment this is not as easy.

As long as there are less than 14 significant digits, printf(%f) works fairly well:

$big = 1234567890123456;
echo $big, "\n";         # 1.2345678901235E+15
printf("%.0f\n", $big);  # 1234567890123456
