You should read about the function unserialize .
The following code:
print_r(unserialize('a:7:{i:800;s:40:"2a5cc72ffea060a4548ae03d6076f4bd_800.jpg";i:500;s:40:"2a5cc72ffea060a4548ae03d6076f4bd_500.jpg";i:300;s:40:"2a5cc72ffea060a4548ae03d6076f4bd_300.jpg";i:295;s:40:"2a5cc72ffea060a4548ae03d6076f4bd_295.jpg";i:75;s:39:"2a5cc72ffea060a4548ae03d6076f4bd_75.jpg";i:40;s:39:"2a5cc72ffea060a4548ae03d6076f4bd_40.jpg";i:0;s:36:"2a5cc72ffea060a4548ae03d6076f4bd.jpg";}'));
Displays:
Array ( [800] => 2a5cc72ffea060a4548ae03d6076f4bd_800.jpg [500] => 2a5cc72ffea060a4548ae03d6076f4bd_500.jpg [300] => 2a5cc72ffea060a4548ae03d6076f4bd_300.jpg [295] => 2a5cc72ffea060a4548ae03d6076f4bd_295.jpg [75] => 2a5cc72ffea060a4548ae03d6076f4bd_75.jpg [40] => 2a5cc72ffea060a4548ae03d6076f4bd_40.jpg [0] => 2a5cc72ffea060a4548ae03d6076f4bd.jpg )
The information you need is stored in the array under the key 800 . Save the result of the function unserialize into a variable and work with it.
For example:
$images = unserialize('тут ваша строка'); print $images[800];
unserialize()will make it again the structure that was serialized - Mikeэто не массив, а строка- Oruuu !!! - Alexey Shimanskyj
