In PHP how to sort a file in reverse?
i have a text (text.txt) file like thi开发者_JS百科s:
shir
beer
geer
deer
i have also a php page with that source:
<?php
foreach (glob("*.txt") as $filename) {
$file = $filename;
$contents = file($file);
$reverse = array_reverse($file, true);
$string = implode("<br>" , $contents);
echo $string;
echo "<br></br>";
}
?>
I want that in the php page it will show:
deer
geer
beer
shir
from the end of the file to the beginning.
thank youLooks like you are reversing the file name and not the contents.
Do
$reverse = array_reverse($content); // you can drop 2nd arg.
$string = implode("<br>" , $reverse);
in place of
$reverse = array_reverse($file, true);
$string = implode("<br>" , $contents);
Also you can remove the temp variables from you script and do:
foreach (glob("*.txt") as $filename) {
echo implode("<br>" , array_reverse(file($filename))) . "<br></br>";
}
<?php
foreach (glob("*.txt") as $filename) {
$file = $filename;
$contents = file($file);
$reverse = array_reverse($contents, true);
$string = implode("<br>" , $reverse);
echo $string;
echo "<br></br>";
}
?>
Your result was a $contents, without reverse.
