<?php
For ($i =0 $i <10; $i + +) {
?>
<input type= "checkbox" Name= "ch[]" value= "<?= $i;? > ">
<input type= "text" name= "t1[<?= $i;? ] "value=" content to be transferred >

3, accept also use an array:

<?php
$ch =$_post[' ch '];
$t 1=$_post[' T1 '];
$t 2=$_post[' T2 '];

foreach ($ch as $a)
{
$p _t1= $t 1[$a];

}
?>

　　Here's another tip: the settings you need to upload a large volume file in PHP

Needless to say, you have to find the PHP configuration file php.ini trouble:

Open PHP.ini, first find
;;;;;;;;;;;;;;;;
; File uploads;
;;;;;;;;;;;;;;;;
Area, there are several parameters that affect file uploads:

File_uploads = on; whether to allow the switch to upload files over HTTP. The default is on, which is open

In

; Data handling;
;;;;;;;;;;;;;;;;;
Area, there is one more:

Post_max_size = 8m refers to the maximum value that can be received by the form Post to PHP, including all the values in the form. The default is 8M

Generally, set the above four parameters, upload <=8m file is not a problem, in the normal network situation.

However, if you want to upload >8m files, only set up the above four will be able to do. Unless your network really has 100m/s upload high-speed, otherwise you have to care about the following parameters:

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

Max_execution_time = 600, maximum time for each PHP page to run (seconds), default 30 seconds

Max_input_time = 600: The maximum time required for each PHP page to receive data, default 60 seconds

Memory_limit = 8m, maximum memory consumed by each PHP page, default 8M

After the above parameters are modified, the network allows the normal situation, you can upload large volume files.

Well, set it up and try it now. Click on the 1200 large m file upload
