And*_*man 8 php file-extension file-exists
请注意,我希望隔间号码更改.
<?php
$compartment = "1";
/* HERE I NEED SOME SCRIPT TO FIND THE EXTENSION OF THE FILE NAME $compartment AND TO SAVE THAT AS A VARIABLE NAMED 'EXTENSION'.*/
if (file_exists($compartment.$extension)) {
echo "$compartment.$extension exists!
} else {
echo "No file name exists that is called $compartment. Regardless of extension."
}
?>
<?php
$compartment = "2";
/* HERE I NEED SOME SCRIPT TO FIND THE EXTENSION OF THE FILE NAME $compartment AND TO SAVE THAT AS A VARIABLE NAMED 'EXTENSION'.*/
if (file_exists($$compartment.$extension)) {
echo "$compartment.$extension exists!
} else {
echo "No file name exists that is called $compartment. Regardless of extension."
}
?>
谢谢!

你需要glob().
$compartment = "2";
$files = glob("/path/to/files/$compartment.*"); // Will find 2.txt, 2.php, 2.gif
// Process through each file in the list
// and output its extension
if (count($files) > 0)
foreach ($files as $file)
{
$info = pathinfo($file);
echo "File found: extension ".$info["extension"]."<br>";
}
else
echo "No file name exists called $compartment. Regardless of extension."
顺便说一句,你上面所做的就是为一个循环而哭泣.不要重复你的代码块,但将其中一个包装成:
$compartments = array(1, 3, 6, 9); // or whichever compartments
// you wish to run through
foreach ($compartments as $compartment)
{
..... insert code here .......
}
