image to string --> string to image

[zebdaag]

Hi i found two codes one puts converts an image to a string...the other one does it the other way around. Now i have the problem that I can't combine them...don't ask my why but i want a code that first converts an image to a string and afterwards converts the string to an image again...how is this possible??

Hope someone can help me with this!
Thanks in advance...i added the script i found.

What exactly are you trying to do???????

[zebdaag]

don't ask me why

Is what i said in my first post, i just want to know if it's possible and how i can do it!

Your post doesn't explain anything! Getting an image file into a string is as simple as:

$string = file_get_content('image.jpg');

What i want is a code that puts an image into a string like you said:
$string = file_get_content('image.jpg');
and then the code should take the string "$string"
and make it an image again. With createImageFromString i think...but i don't know how.
Sorry if it wasn't clear what i wanted, but maybe it sounds so stupid that you can't believe i want this

There's an example of that in the manual . Note the the string in the example has previously been base 64 encoded.

Hi Bokeh, I already found that example that's the one attached in my first post. But the thing is i can't get it to work!! I don't know what 64 means so maybe you can help me a bit further with combining the two code i attached in my first post..

Thanks in advance

Base 64

[zebdaag]

okay well now i know what base64 is but it doesn't help me any further...
cause the image the source i get from php when i do file_get_contents is not base64....

when you see this code:

<?php
$loadFile = "test.jpg";
$im = imagecreatefromstring(file_get_contents($loadFile));
imagejpeg($im);
?>

it looks simpel as **** but why don't i see an image???
why is the only thing i see the source of the image??
can someone help me??

you have to set the content type to image/jpeg or something.

EDIT: try this:

<?php
$im = @imagecreatefromstring(file_get_contents('image.jpg'));
imagejpeg($im);
header ("Content-type: image/jpg");
?>

[bokeh]

<?php
$im = @imagecreatefromstring(file_get_contents('image.jpg'));
imagejpeg($im);
header ("Content-type: image/jpg");
?>

You have the order a bit wrong; the header needs to be sent before the image:

<?php
header ('Content-Type: image/jpg');
imagejpeg(imagecreatefromstring(file_get_contents('image.jpg')), null,100);
?>

But all this is pretty pointless apart from being a learning exercise because nothing is actually being done with the image itself.

It would work on servers with output buffering turned on by default. This is probably about 5% of servers. My recommendation is to write code that will work in 100% of cases.
