感謝的想法提前

Answer 1

它的基本。

<?php  
$ext= explode(".",$filename); // explode filename by "." 
$extension= $ext[1];// get extension. 
if($extension=="pdf") 
{ 
// do something 
} 
elseif($extension=="jpg" ||$extension=="png".....) 
{ 
// do something 
} 
?> 

Answer 2

可以使用pathinfo()

<?php 
$file1 = pathinfo('file.pdf'); 
$file2 = pathinfo('file.jpg'); 

echo $file1['extension']; // will output pdf 
echo $file2['extension']; // will output jpg 
?> 

Answer 3

$file1 = pathinfo($file1Path); 
$file2 = pathinfo($file2Path); 

if($file1['extension'] === $file2['extension']) { 
    //The extensions are the same. 
} 

if($file1['extension'] === 'pdf') { 
    //extensions is PDF and so on 
} 

Answer 4

$fileExt = explode('.','yourFileWithExtension'); 
if($fileExt[1] == 'pdf') { 
    //move to attachments folder 
} else { 
    // some other folder 
}

$file_extension = pathinfo("example.pdf", PATHINFO_EXTENSION) 
if ($file_extension == "jpg") { 
    your code here to send to image folder 
} else if ($file_extension == "pdf") { 
    your code here to send to attachments folder 
}
