extract string from string then display

[calmchess]

how do i extract  specific characters from a string and then use/display whats left over?

[dyluck]

Can you write an example of the problem and then what you would like to see?

[calmchess]

../root/content/calmchess55.jpg...........extract..............use/display>>>>>> calmchess55.jpg

 

 

PS. the lenght of the  string is variable

[dyluck]

../root/content/calmchess55.jpg...........extract..............use/display>>>>>> calmchess55.jpg

 

 

PS. the lenght of the  string is variable

 

$string = "../root/content/calmchess55.jpg";

 

$result = end(explode("/",$string));

 

echo $result;

[calmchess]

i need to extract a string from it not explode it i would need to extact all the characters no just explode the slashes the slashes might not be there it was just an example

Oh ok.    Unfortunatly your not being very descriptive.

 

Do you know which pieces of string you will be extracting?

 

[calmchess]

input username extract username  use remaining string......sorry for not bein descriptive i just don't know how to do it so i'm writing this as we go.

[teamatomic]

Do you have the username saved as a session var?

$_POST['username'] this is part of an administrative web page so the username is being inputed.......i need to extact that username and then extract other string from that string if the username has a number on the end of it it will mess up my processing because i'm extracting the username along with its number if it has some then i  change the new string by subtracting from its id number ........this probably isn't very clear but i think you will get the idea

[calmchess]

here is what i'm trying

 

<?php session_start();?>

<tr><td>Admin Name:</td><td><input  type="text" name="admin" maxlength="14" width= "30"value =""> </td></tr>
<tr><td>Create in Private Room?:</td><td>
<SELECT NAME="priv">
<OPTION VALUE="1">yes
<OPTION VALUE="0">no
</SELECT>
</td></tr>
<tr><td><a href="http://www.privatechatnow.com/currentwebsite/">Home</a></td></tr>

or die(mysql_error());  
}else{
$result = mysql_query("SELECT picpath2 FROM page0.page0 where username='$adminname'") 
or die(mysql_error());
}
$row = mysql_fetch_row($result);
$db_arr0 = $row[0];
$arr_unser = unserialize($db_arr0);

You explanation is still not really clear but...this is what I might do.

work the username to see if it fits what I need then use str_replace to replace the username with nothing in the string I want to use. Make sense?

I think the best way is for you to give us 10-20 EXAMPLE inputs and the data you want to extract from them.

[calmchess]

need to extract calmchess55 from each link and then subtract 1 from each  remaining string such as 1.jpg the username can be variable with or without  a number so i need hack off the username and change the remaining string.

 

../recContent/calmchess55/calmchess551.jpg

../recContent/calmchess55/calmchess552.jpg

../recContent/calmchess55/calmchess553.jpg

../recContent/calmchess55/calmchess554.jpg

[teamatomic]

Then the first thing to do is us basename on each string to get usernamexxx.jpg.

Then use str_replace to change the username to nothing so you get xxx.jpg. Then explode on the dot so you get xxx and subtract 1 from it.
