让我们假设以下是我们的变量，其中我们有一个.mp4路径文件−
$movieFileType="demo.mp4";
要检查上述文件是否为视频类型，请使用end()和explode()。您需要在strtolower()中设置此条件并检查条件 −
if(strtolower(end(explode(".",$movieFileType))) =="mp4") {
}
else {
}Example
<!DOCTYPE html>
<html>
<body>
<?php
$movieFileType="demo.mp4";
if(strtolower(end(explode(".",$movieFileType))) =="mp4") {
echo "The movie ",$movieFileType," is of video type.";
} else {
echo "The movie ",$movieFileType," is not of video type.";
}
?>
</body>
</html>这将产生以下输出 −
输出
The movie demo.mp4 is of video type.
