Skip characters in a <textarea> for output

[cjbeck71081]

I have a form i created that takes text entered in a <textarea> and adds some tags to it like this

 

Form1.html

<form action="test.php">

<textarea>http://us10.stupid.com/Myfile.jpg</textarea>

 

What i would like to do is remove the leading 11 characters from the variable and add some tags to it so it might look like this:

 

test.php

<php

$file = $POST_['textarea'];
((((trim $file by 11 characters from the left)))))
$file1 = "<img src='http://www.";
$totalfile = "$file1'>";

echo ($totalfile);

?>

 

So that it outputs

http://www.stupid.com/Myfile.jpg

 

 

Any help is appreciated.

 

Thank You

Chris Beck

<?php
$file = 'http://us10.stupid.com/Myfile.jpg';
$file = 'http://www' . substr($file, 11);
echo $file;         //--> http://www.stupid.com/Myfile.jpg 
?>

A quick look round and I'm sure you can use:

 

explode() - http://uk3.php.net/manual/en/function.explode.php

 

or

 

preg_split()

 

or

 

split()

...and Barand not only types quicker but comes up with a much better way of doing it!

aww poor fearpig... *pats on the back*

Thanks guys but now to throw a wrench, (and there may not be a way of doing this) the server changes sometimes from

 

http://us10.server.com/jioasfjdasda.jpg

 

to

 

http://us2.server.com/jaksdfasa.jpg

 

but the www.server.com always works

 

so the substr works to eliminate the first 11 characters in the us10 one.  Is there any way to put a clause in that will allow for it to remove 10 characters if it a certain setup.  Possibly a "like" clause or something, i dont know.

 

Thanks for the help.

Perhaps the pregsplit would work in this case if you put in a removal clause of

 

"http://" and

"us10" and

"us2" and any other servers they commonly use.

 

Any Ideas?

oh pishposh... lol... no need for a like statement :-) just use this :-)

 

<?php
function get_ending($filepath){ 
return substr($filepath, strpos($filepath, strchr($filepath, ".")));
}

$file = 'http://us10.stupid.com/Myfile.jpg';
$file = 'http://www' . get_ending($file);
echo $file;
?>

not tested... but it should work

[cjbeck71081]

get_ending is not a function of PHP

[taith]

it is after i made it... not a default one, but you can make your own...

This is how I'd do it:

 

<?php

$file = "http://us10.stupid.com/Myfile.jpg";

$bits = explode(".", $file);

$file = "http://www." . $bits[1] . "." . $bits[2] . "." . $bits[3];

echo $file;

?>

[taith]

ya... mine grabs everything after the first . as in...

http://www.google.ca --> google.ca

and https://wwwl.google.com --> google.com
