Question reguarding echo str_replace()

[al3x8730]

I'm trying to replace more than one thing, but if I repeat the function echo str_replace() then it doesn't work because it repeats other things. how would I replace more than one thing?

[cooldude832]

Like

<?php
$string = "Joe goes to school";
$string = str_replace("Joe","Sally",$string);
$string = str_replace("school", "mall",$string);
echo $string;
#Sally goes to the mall
?>

Do you want to replace one thing multiple times, multiple things one time or multiple things multiple times?

Actually I'm trying to replace something in a directory contents listing.

 

I want to replace 3 file names.

 

And for 1 I'm using this:

<?php

$handle=opendir(".");

while (($file = readdir($handle))!==false) {
echo str_replace( "index.php", "", $file ) . " <br />";

}
closedir($handle);


?>

 

But if I repeat the line: echo str_replace( "index.php", "", $file ) . " <br />"; and just replace it with a different file name It doesn't work because it repeats the other files names.

Why didn't you use the rename() function?

[The Little Guy]

$find = array('Joe','school');
$replace = array('Bob','work');
$string = "Joe goes to school";


$new = str_replace($find,$replace,$string);

echo $new;

I don't want to rename the file, just rename it on that list.

I presume you mean you don't want the index.php file displayed in the generated list. You should do this instead:

<?php

$handle = opendir(".");

$ignore_files = array('.', '..', 'index.php');

while (($file = readdir($handle))!==false)
{
    // do not display files listed in the ignore_files array
    if(!in_array($file, $ignore_files))
    {
        echo $file . '<br />';
    }
}

closedir($handle);

?>
