putting multiple functions together

[manicleek]

how can I put multiple functions into one parent function,

for example, if on my out put I normaly have:

<?= nl2br(ucfirst(striptags($sometext))) ?>

how can I define all those at the beginning of the page so I would only have to put something like:

<? textformat($sometext) ?>

You create a user-defined function that takes as is input the innermost text, runs that text through all the functions, and returns the result.

Here's what I would do:

<?php
function textformat($str)
{
   return (nl2br(ucfirst(striptags($str))));
}
?>

so:

function textformat($sometext) {

striptags($sometext);
ucfirst($sometext);
nl2br($sometext);

}

is that correct?

No.

Take a look at kenrbnsn's example.

What you left out was returning a value.
What you did wrong in your function was to run the output of one function into the next function. You just performed three transforms on the same single text.

After this is up and going, you might also want to add some "error handling"..(note the quotes)

<?php
function textformat($str = "404")
{
  if ($str == "404") {
      return "404 - nothing to format"
    }
  else {
      return (nl2br(ucfirst(striptags($str))));
    }
}
?>
