$filename without extension

i have a script which us to read jpg images in a folder where this script file exist and displays in a gallery on browser
it read file name by $filename
i want to change little that it read file names but not its extension

please tell me how can i do this

 

try using the explode method ...

$newfilename = array();
$newfilename = explode(".",$filename);
$filename = $newfilename[0];

try this and tell me how it works ..

 

You should use this method instead:

$filename = '/www/path/to/picture/picture.jpg';

$fileParts = pathInfo($fileName);

PHP:

this method will give you access to specifics using a well defined array instead of an arbitrarily indexed array:

echo $fileParts['dirname'];     //  /www/path/to/picture
echo $fileParts['basename'];    //  picture.jpg
echo $fileParts['filename'];    //  picture
echo $fileParts['extension'];   //  jpg

PHP:

The reason you'd want to do it this way is to provide fault tolerance for random naming conventions.

Lets say your file name is = 'Auth.class.php'
If you explode on '.', the first element [0] will give you 'Auth', which is not
the correct filename.

 

$file = 'image1.3242542.abcdefg.jpg';

//reading the image file name except the dot and last three letter
echo substr($file,0,-4); 

PHP:

 

$file = 'sweetPic.jpeg';

 

Orrrr....:

echo basename($filename, '.jpg');

PHP:

 

He said jpg

 

Lol, well in a real life situation he would probably accept every kind of image, even .jpeg's . . .

pathInfo();
// is the best method to go with.

PHP:

 

Okay here's your code. work in all file extension.

$file = 'image1.3242542.abcdefg.jpeg';
echo substr($file,0,-(strlen(strrchr($file,'.'))));

 

PHP:

 

But why calling 3 functions when all you need is one? pathinfo() and basename() will work just fine...

 

Agreed- though either way does work, I'm sure we could even come up with a 4th way of doing this x]

 

you have to specify jpg when you using basename.

 

4th way i have my own last char of did not know about the php 1 ... but i like strrchr over pathinfo() cause path info does a lot internally ....

 

Agreed, pathinfo() was design to get file path and it's do more work internally to find the file path.
