Homephp教程php手册总结:表单复选框向PHP传输数据的研究

  表单复选框就是checkbox

  1、checkbox的应用

  

  2、由于我传输的是在php循环中产生的数组,因此value也要设成变量:

         for($i=0;$i   ?>
   
     
     
      :
      :

 3、接受时也要用数组:

          $ch=$_POST['ch'];
      $t1=$_POST['t1'];
      $t2=$_POST['t2'];
     
      foreach($ch as $a)
      {
         $p_t1=$t1[$a];
         $p_t2=$t2[$a];
       }
     ?>

  再给大家总结一个小技巧:PHP中上传大体积文件时需要的设置

不用说,还得找PHP配置文件php.ini的麻烦:)

打开php.ini,首先找到
;;;;;;;;;;;;;;;;
; File Uploads ;
;;;;;;;;;;;;;;;;
区域,有影响文件上传的以下几个参数:

file_uploads  =  on  ;是否允许通过HTTP上传文件的开关。默认为ON即是开

upload_tmp_dir  ;文件上传至服务器上存储临时文件的地方,如果没指定就会用系统默认的临时文件夹

upload_max_filesize  =  8m  ;望文生意,即允许上传文件大小的最大值。默认为2M


;;;;;;;;;;;;;;;;;
; Data Handling ;
;;;;;;;;;;;;;;;;;
区域,还有一项:

post_max_size  =  8m ;指通过表单POST给PHP的所能接收的最大值,包括表单里的所有值。默认为8M

一般地,设置好上述四个参数后,上传

但如果要上传>8M的大体积文件,只设置上述四项还一定能行的通。除非你的网络真有100M/S的上传高速,否则你还得关心关心下面的参数:

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;

max_execution_time  =  600 ;每个PHP页面运行的最大时间值(秒),默认30秒

max_input_time = 600 ;每个PHP页面接收数据所需的最大时间,默认60秒

memory_limit  =  8m  ;每个PHP页面所吃掉的最大内存,默认8M


把上述参数修改后,在网络所允许的正常情况下,就可以上传大体积文件了。

好了,设置好现在就可以一试。点击一200大M的文件上传一下

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
