从图像文件名 php 中删除扩展名

Question

I am loading a folder of images into a html page using the following php code.

The problem I am having is that the file name which is being brought through in order to be used as the image caption is showing the file extension.

The part of the code where the name is being pulled is the title='$img'

How do I get it to remove the file extension?

<?php
$string =array();
$filePath='images/schools/';  
$dir = opendir($filePath);
while ($file = readdir($dir)) { 
    if (eregi("\.png",$file) || eregi("\.jpeg",$file) || eregi("\.gif",$file) || eregi("\.jpg",$file) ) { 
        $string[] = $file;
    }
}
while (sizeof($string) != 0) {
    $img = array_pop($string);
    echo "<img src='$filePath$img' title='$img' />";
}

?>

Answer 1

您可以使用pathinfo获取没有扩展名的文件名，因此对于 title='' 您可以使用pathinfo($file, PATHINFO_FILENAME);

Answer 2

$file_without_ext = substr($file, 0, strrpos(".", $file));

Answer 3

For a "state-of-the-art" OO code, I suggest the following:

$files = array();
foreach (new FilesystemIterator('images/schools/') as $file) {
    switch (strtolower($file->getExtension())) {
        case 'gif':
        case 'jpg':
        case 'jpeg':
        case 'png':
            $files[] = $file;
            break;
    }
}

foreach ($files as $file) {
    echo '<img src="' . htmlentities($file->getPathname()) . '" ' .
         'title="' . htmlentities($file->getBasename('.' . $file->getExtension())) . '" />';
}

Benefits:

• You do not use the deprecated ereg() functions anymore.
• You escape possible special HTML characters using htmlentities() .

Answer 4

you can get rid of file extention with substr, like this:

$fileName =  $request->file->getClientOriginalName();
$file_without_ext = substr($fileName, 0, strrpos($fileName,"."));
