Code For Limit Characters to 25

[jkane]

I want to limit this tag to 25 characters when file runs, now it can be anywhere from 7-40 characters

$teams = explode(" v ",$hie->Name);

 

 

 

foreach ($xml->xpath("//Competition[@id='NBA' and @sprtyp='BK']/Match") as $hie) {
    $timestamp = strtotime($hie->Date);
    $day = date('d' , $timestamp);
    $month = date('M', $timestamp);
    $time = date('h:i A', $timestamp-$timeDiff);
    $teams = explode(" v ",$hie->Name);

A lone line of code and a block of meaningless and incomplete code that is doing something with an outrageous index name on an array?  What IS this?

And just what is a "tag" in your world here?

substr

If $teams[0] or $teams[1] is less than 25 characters, substr() will return the whole value.

My recommendation?  Don't do it.

$teams is an array of Strings with, I assume, two elements (as in "A v B") so you don't want to restrict the number of elements there. 

 

If you restrict the length of the Name Xml element, then you run the risk of losing the second team entirely or even breaking your own code:

Arbitrarily cutting this at 25 characters, your code only just gets the ' v ' delimiter that the explode() function requires.  If you did the cutting at twenty characters, or if the former name were just two characters longer, then you would lose that delimiter and your code might well break, receiving only one element in the resulting $teams value.

$hie->Name = 'Arnold Schwarzenegger v Sylvester Stallone' ; 
                                      ^
                       1         2    |    3
              123456789012345678901234567890

 

I have to ask "why" you want to do this at all ...

If your application allows names to be longer than 25 characters, why are you truncating them? 

 

I suspect your Users would be less than impressed if they chose much longer names and your code just chopped them off at some arbitrary limit.

Is it better I post a whole PHP  file as an attachment?

 

Yes I need  team 1 and team 2  to 25 characters
 

There’s a reason for this format better in the application

Just to clarify, do you want the name for team 1 to be 25 characters? And the name for team 2 to be 25 characters? So you would have 50 characters at most for both team names?

If so, you could try requinix's suggestion above. You already exploded the names. From there, you can use substr() to limit each name.
