PHP使用gmdate实现将一个UNIX 时间格式化成GMT文本的方法

string gmdate (string $Format)
string gmdate (string $Format, int $Time)

<?php
echo "When this page was loaded,\n";
echo 'It was then ', gmdate ('r'), "\n";
echo 'The currend gmdate was ', gmdate ('F j, Y'), "\n";
echo 'The currend gmdate was ', gmdate ('M j, Y'), "\n";
echo 'The currend gmdate was ', gmdate ('m/d/y'), "\n";
echo 'The currend gmdate was the ', gmdate ('jS \o\f M, Y'), "\n";
echo 'The currend time was ', gmdate ('g:i:s A T'), "\n";
echo 'The currend time was ', gmdate ('H:i:s O'), "\n";
echo gmdate ('Y');
gmdate ('L')?(print ' is'):(print ' is not');
echo " a leap year\n";
echo time ('U'), " seconds had elapsed since January 1, 1970.\n";
?>
