does a file exist?

[unistake]

Hi all,

 

I want to make a script that identifies if an image JPG file exists.

 

Would somthing like this work?

 

<?php
$file = "images/image.jpg";
if ($file > 0) {
echo "file exists";
}
else { echo "no file"; }
?>

SO

<?php
$filename = '/path/to/foo.txt';

if (file_exists($filename)) {
    echo "The file $filename exists";
} else {
    echo "The file $filename does not exist";
}
?>

[EDIT] I should learn to type quicker ;p

 

$yourfile = "something.jpg";

 

if(file_exists($yourfile)){

//case true

//do stuff

}

else{

//case false

//show error message

}

 

There ya go!

you more than likely want to use

$yourfile = '/path/to/something.jpg';

 

Use the full system path to the file to prevent issues with the file_exists function results.
