文档名称（将 php 转换为？）

Question

Hi I am currently using php to add the document name so example.

folder/<?phpecho basename(__FILE__, '.' . pathinfo(__FILE__,
PATHINFO_EXTENSION));?>_button.png 

What i have noticed is that by using php to do this and having multiple examples of this it is dramatically increasing my page load time. What i wish is for a similar method using client side scripting.

If you are truly convinced that this is slowing your page times down, then you need to prove it. Use the microtime() function to test each function call and see what's actually slowing things down. For example:

<?php
    $t0 = microtime(TRUE);
    $ext = pathinfo(__FILE__, PATHINFO_EXTENSION);
    $t1 = microtime(TRUE);
    $filename = basename(__FILE__, '.' . $ext);
    $t2 = microtime(TRUE);

    echo "pathinfo() took " . $t1-$t0 . " seconds.  ";
    echo "basename() took " . $t2-$t1 . " seconds.  ";
    echo "total time: " . $t2-$t0 " . " seconds.";
?>

And if you determine that it is taking too long, find a better way to do it. Or, at least save this calculated value to a variable and echo that throughout the multiple places you need it.
