php保留小数点后的0

Submitted by admin on 2009, August 8, 4:05 PM

round函数可以截取小数点的位置,且可以进位,但如是小数点后的数为0时,也会去掉

如下函数可以达到效果

$money="122.0";  
  $formatted   =   sprintf("%.1f",   $money);  
  echo   $formatted;

 

$formatted=number_format($money,   1);

/usr/bin/ld: cannot find -lltdl

Submitted by admin on 2009, January 19, 5:21 PM

编译PHP5时提示

/usr/bin/ld: cannot find -lltdl
collect2: ld returned 1 exit status
make: *** [libphp5.la] Error 1

安装

yum install libtool-ltdl

yum install libtool-ltdl-devel

就可以了.

[root@localhost ~]# cat /etc/redhat-release
CentOS release 5.4 (Final)
[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.18-164.el5 #1 SMP Thu Sep 3 03:28:30 EDT 2009 x8
6_64 x86_64 x86_64 GNU/Linux
php-5.2.12

在用yum安装libtool-ltdl-devel后编译php-5.2.12提示下如

/usr/lib/libltdl.so: could not read symbols: File in wrong format
collect2: ld returned 1 exit status
make: *** [libphp5.la] Error 1

安装php-5.2.13没问题

----------------------------------

yum install libpng


configure: error: libjpeg.(a|so) not found
ln -sf libjpeg.so.62.0.0 libjpeg.so


configure: error: libpng.(a|so) not found.
yum install libpng-devel
