Array is string after unserialize()

griddie

Hi there,

Guess I'm having a braindead day and hope somebody can point me the right direction. :rolleyes:

Issue is:

serialized array in db:
s:93:"array(
0 => '75',
1 => '100',
2 => '150',
3 => '240',
4 => '500',
5 => '1024',
);";

This is the exact value in the db table sizes.

When doing:
$resize_dimensions = unserialize($row['sizes']);

All I'm getting back in var: "$resize_dimensions" is a string instead of an array.

"print_r()" and "echo $resize_dimensions;" --- comes back with:
array( 0 => '75', 1 => '100', 2 => '150', 3 => '240', 4 => '500', 5 => '1024', );

As this is a string, how the heck am I getting this string back to be an array ? :o

Sorry for asking silly questions... But my brain is somehow gone today...

Thanks a million
griddie

It is really an array.

Try
echo $resize_dimensions[0];
.. should give you '75'

griddie

Thank you for your reply halojoy :-)

Unfortunately doing: echo $resize_dimensions[0];

Comes back with: a instead of 75 :-(

the problem is before you put serialized value into database.
this is how the serialized string should look in your database field:

a:6:{i:0;s:2:"75";i:1;s:3:"100";i:2;s:3:"150";i:3;s:3:"240";i:4;s:3:"500";i:5;s:4:"1024";}

The code I have used to serialize is this:

<?php

$first = array(
0 => '75',
1 => '100',
2 => '150',
3 => '240',
4 => '500',
5 => '1024'
);

$second = serialize($first);

echo $second;

?>

yeah I was wondering why the string in the DB looks like half serialized...

This is for an API I am writing for a 3rd party script.

So I guess they are doing something else instead of just serializing the array.

Maybe i should just parse the string I get back with regex instead and create a new array from it.

Not the best option I guess but at least it would do the trick.

What do you think ?

Thank you very much :-)

I dont know if there is a smart way
to turn that 'array-string' into a real array.
"array( 0 => '75', 1 => '100', 2 => '150', 3 => '240', 4 => '500', 5 => '1024', )"
Probably there is some way.

Best, of course, is to fix how the serialized value is put into database.
The other is a second hand solution.

griddie

That's true, putting it in the database nicely serialized would be the best way.

Think I will contact their support and ask them if there is a reason why the array is "serialized" like this.

From what I understand, parsing the string and make my own array() out of it would be the way to go until it get's fixed by the developers of the script.

Thank you very much for your effort and time :-)

Wish you a good New Years Eve in advance :-)

You could just use eval()

$data = "array( 0 => '75', 1 => '100', 2 => '150', 3 => '240', 4 => '500', 5 => '1024', )";
$code = '$array = '.$data.';';
eval($code);
echo '<pre>'.print_r($array, true).'</pre>';

griddie

Thank you jay6390,

you made my day :-)

Still feeling like braindead though but the coding can go on hehe...

After trying trying trying, there is a light at the end of the tunnel.

eval(); works just perfectly.

Have a good new years eve in advance.

This Forum is to be the best ressource when it come to PHP :-)

No problem. Have a great NYE yourself griddle! 🙂

Almost looks as if they did a serialize(print_r($array, TRUE)); instead of just serialize($array);, but who knows.
