The following code gives me two different outputs:
$number = '1562798794365432135246';
echo $number;
echo number_format($number);
Can anyone explain this?
EDIT: forgot to mention, the above gives me "1562798794365432135246 1,562,798,794,365,432,233,984". Note the last six digits are completely different for no obvious reason (all i was asking it to do was insert thousand separators).
Here's what worked best for me when trying to script this (in case anyone else comes across this like I did):
$ pecl -d php_suffix=5.6 install <package>
$ pecl uninstall -r <package>
$ pecl -d php_suffix=7.0 install <package>
$ pecl uninstall -r <package>
$ pecl -d php_suffix=7.1 install <package>
$ pecl uninstall -r <package>
The -d php_suffix=<version> piece allows you to set config values at run time vs pre-setting them with pecl config-set. The uninstall -r bit does not actually uninstall it (from the docs):
vagrant@homestead:~$ pecl help uninstall
pecl uninstall [options] [channel/]<package> ...
Uninstalls one or more PEAR packages. More than one package may be
specified at once. Prefix with channel name to uninstall from a
channel not in your default channel (pecl.php.net)
Options:
...
-r, --register-only
do not remove files, only register the packages as not installed
...
The uninstall line is necessary otherwise installing it will remove any previously installed version, even if it was for a different PHP version (ex: Installing an extension for PHP 7.0 would remove the 5.6 version if the package was still registered as installed).
It does not make sense to combine WinEnter and FileType events in the same autocmd rule; the first matches against the buffer's filename while the latter matches against the buffer's filetype.
Instead, use a single autocmd triggered whenever a buffer is entered / displayed in a window, and choose the colorschmeme with a conditional on the &filetype.
:autocmd BufEnter,FileType *
if &ft ==# 'c' || &ft ==# 'cpp' | colorscheme darkblue |
elseif &ft ==? 'r' | colorscheme desert |
else | colorscheme default |
endif
Make sure whatever class engine belongs to implements a horsePower property, and/or has a horsePower instance variable, and/or manually implements setHorsePower: and horsePower methods.
You are getting the error because you're trying to set the value of the horsePower key but engine's class does not properly implement a way to set the horsePower key.
Never used any of those, but they look interesting..
Take a look at Gearman as well.. more overhead in systems like these but you get other cool stuff :) Guess it depends on your needs ..
number_format(), as stated by the PHP manual, converts a float into a string with the thousands groups with commas.If you're trying to cast a string to an integer, you can do so like this:
However, be careful, since the largest possible integer value in PHP is
2147483647on a 32-bit system and9223372036854775807on a 64-bit system. If you try to cast a string like the one above to int on a 32-bit system, you'll assign$numberto2147483647rather than the value you intend!The
number_format()function takes a float as an argument, which has similar issues. When you pass a string as an argument tonumber_format(), it is internally converted to a float. Floats are a little more complicated than integers. Instead of having a hard upper bound like an integer value, floats progressively lose precision in the least significant digits, making those last few places incorrect.So, unfortunately, if you need to format long strings like this you'll probably need to write your own function. If you only need to add commas in the thousands places, this should be easy - just use strlen and substr to get every set of three characters from the end of string and create a new string with commas in between.
