Hi.,,
I am new to php.
I am developing one tree grid in extjs.were i need to display field in tree format.so for front end i need to send the encoded data.
I want 2 functions for encoding and decoding a string variable,multidimensional array,variables with a set of delimiters.
For example if i am having an array.........
array(
array( "task" => "rose",
"duration" => 1.25,
"user" => 15
),
array( "task" => "daisy",
"duration" => 0.75,
"user" => 25,
),
array( "task" => "orchid",
"duration" => 1.15,
"user" => 7
),
array( "task" => "sunflower",
"duration" => 1.50,
"user" => 70
)
);
i want to encode all the array fields or single field as..........
array(
array( "task" => "rose",
"duration" => 1.25,
"user" => 15
),
array( "task" => "daisy",
"duration" => 0.75,
"user" => 25$sbaa,
),
array( "task" => "orchid",
"duration" => 1.15,
"user" => 7$!ass,
),
array( "task" => "sunflower",
"duration" => 1.50,
"user" => 70$!abc
)
);
So like this only i need to encode string,variables with delimiters.........
later all the encoded values to be decoded before its taken back to back end.....for this i have to use this plugin..........
encode.class.php...........

from this plugin i need to use encode and decode functions for my functions.........
if anyone can help me on this.......it will be very much useful for me.......
