How to split data

[brooksh]

How can I split this data and then remove it? I need to split data by ; then split each one of those.

$data = "page=1&data=1:21;2:34;5:57&a=yes";

 

So I will get:

 

$category[0] = 1;

$sub_category[0] = 21;

$category[1] = 2;

$sub_category[1] = 34;

$category[2] = 5;

$sub_category[2] = 57;

<?php

$data="1:21;2:34;5:57";

$data=split(";",$data);

foreach($data as $c) {

$result=split(":",$c);

$category[]=$result[0];

$sub_category[]=$result[1];

}

print_r ($category);

print_r ($sub_category);

?>

Explode splits a string into an array e.g.

 

<?php
$string="1&2&3&4&5&6&7";

$array=explode("&",$string);
?>

 

Array will be 7 in lenght containg

 

1

2

3

4

5

6

7

 

so ur example would be

 

<?php
$data = "page=1&data=1:21;2:34;5:57&a=yes";

$array=explode(";",$data):
//array[0] will be 1:21
//array[1] will be 2:34 
//ect u get the idea, it simple from then on.
//just loop though the array do as u wish then use implode to join them back to string if needed.
foreach ($array as $k => $v)
{
// do what u want to the data here 
}

$string=implode($array);

?>

 

Notes on implode

http://php.net/manual/en/function.implode.php ;

 

If u want to remove elements from an array you can use unset($array[4]).

<?php
$data = "page=1&data=1:21;2:34;5:57&a=yes";

$array=explode(";",$data):
//array[0] will be 1:21
//array[1] will be 2:34 
//ect u get the idea, it simple from then on.
//just loop though the array do as u wish then use implode to join them back to string if needed.
foreach ($array as $k => $v)
{
// do what u want to the data here 
}

$string=implode($array);

?>

 

 

$array[0] = page=1&data=1:21;2:34

 

How can I get rid of the page=1&data=

[brooksh]

$data = preg_match("/data=(.*)&/", $data, $matches);

Although its Solved it does not really help u out that much .

 

Have a look at substr()
