php替代javascript的日期（）。getTime（）

Question

With below javascript code I get timestamp

<script>
Date().getTime()
</script>

Which results in 1454497242551

how can I get the same kinda timestamp via php

Answer 1

PHP and large integers seem to cause issues but perhaps you could try:

quick and easy way
-----------------
echo sprintf('%013.0f', microtime(1)*1000 );

alt version, but no more accurate
---------------------------------
$pieces = explode( " ", microtime() );
$ctstmp = bcadd( ( $pieces[0]*1000 ), bcmul( $pieces[1], 1000 ) );

echo $ctstmp;


In Javascript
var ts=new Date().getTime();


results:
--------
Javascript:      1454592264750
PHP ( sprintf ): 1454592264020
PHP ( alt ):     1454592264020

It is correct to multiply by 1000 because microtime(true) returns the Unix timestamp in seconds as a float and the javascript new Date().getTime() returns the number of milliseconds since the DateTime epoch ( where they both use the epoch time of 1970/01/01 )

Ok, there is a difference between the PHP and the Javascript - that could be due to rendering on the page.
