Strip extensions

[dreamwest]

How can i strip an extension from a string??

 

I like crosscountry.wmv

 

To be just:

 

I like crosscountry

 

[abdfahim]

$myvar="I like crosscountry.wmv";
$myarr=explode(".",$myvar);
echo $myarr[0];

 

if you have any other dot (.) in the string, its better to use preg_match

[nuttycoder]

or use str_replace:

 

<?php 
$theFile = 'I like crosscountry.wmv';
$theFile = str_replace("I like crosscountry.wmv","I like crosscountry",$theFile);
echo $theFile;
//outputs I like crosscountry
?>

@nuttycoder .. how can you know what is there before dot(.) ??

[nuttycoder]

Sorry not sure what you mean.

[abdfahim]

see, if you know what to replace with, then you dont have to do anything. for instant, I wrote "I love abc.com", person B wrote "I love def.com" etc.... now, when you write your code, you have to replace my string with "I love abc", person B's string with "I love def" and so on. If you use str_replace only, then how can you do it? Its not a constant string definitely. It must vary with user, otherwise, if as a coder you know the string which is constant, why should you need to strip that with code? Just use the Backspace buton on keyboard and delete the unnecessary portion !!!!

[nuttycoder]

yeah I see your point :0)

[void]

oh, come on guys.

 

$str = 'any.title.with.many.dots.wmv';

$title = substr($str,0,strrpos($str,"."));

[abdfahim]

yes void .. there is always many ways to do a thing in php ... no doubt on that .... its not a rocket science .... no need to be impatient ...

I would use the pathinfo function:

<?php
$myvar="I like crosscountry.wmv";
$x = pathinfo($myvar);
echo $x['filename'];
?>

$e = explode(".",$fileName);

unset($e[count($e) - 1]);

$fileName = implode(".",$e);

$myvar="I like crosscountry.wmv";
$x = pathinfo($myvar);
echo $x['filename'];

or yeah.. pathinfo($fileName,PATHINFO_FILENAME);

 

but idk if pathinfo() will do it if that file doesn't exist :S

It will.

[kenrbnsn]

pathinfo works fine whether or not the file exists:

 

<?php
$fe = (file_exists('no.such.file.here'))?'exists':'does not exist';
echo 'file no.such.file.here ' . $fe . "\n";
echo pathinfo('no.such.file.here',PATHINFO_FILENAME) . "\n";
?>
