php.ini

	;====================================================================

	[Fwolf]
	;在 PHP4 中使用 date 等函数的时候，并不需要考虑时区问题，会自动获得本地时间，
	;但 PHP5 中则不行，如果你们有设置好时区，
	;同样的代码在不同的系统可能会产生莫名其妙的问题（比如 Windows 和 Unix 之间）。
	;想要正常使用时间函数，需要在 php.ini 中设置统一的时区：
	date.timezone = PRC
	;也有一个函数，只是需要在程序中使用
	;date_default_timezone_set('Asia/Shanghai');

fwolf / compute-base-convert-safe-length.php

Created October 31, 2013 14:06

Number equal or larger than 100000000000000(1.0E+14) will represent by Scientific Notation(科学记数法), cause base_convert() loose precision. So for larger number, use BC Math or GMP. This array is used to check number string length per base, if string is longer than the array value, it should not use build-in base_convert(). Un-formatted for run usi…

	for ($j = 2; $j < 63; $j ++) {
	$x = $j; $i = 1; $y = $x;
	while ($y < 100000000000000) {
	$i ++;
	$y = pow($x, $i);
	}
	$i --;
	$y = pow($x, $i);
	echo "$x^$i = $y, length " . strlen($y) . "\n";
