How change (replace) element in text?

Question

Good day.

We have code:

function testfunc($text){
 return $text;
}


$text = "Simple text {testfunc(1)} and next simple text and we {testfunc(20)} are happy ";
// number in {testfunc()} only for example - it can be other number or text.

Tell me please how replace {testfunc(1)} on result function testfunc($num)?

P.S.: In result need get next text:

$text = "Simple text 1 and next simple text and we 20 are happy ";

why dont use this? `$text = "Simple text ".testfunc(1)." and next simple text and we ".testfunc(20)." are happy ";` — Baba, Apr 28 '14 at 11:02

Try this:

$newText = preg_replace_callback("/\{testfunc\((\d+)\)\}/","testfunc",$text);

And you'll get array of matches in your "testfunc". For what you want, this code:

I think, it helps you.

<?php

function testfunc($text){
    return $text[1];
}


$text = "Simple text {testfunc(1)} and next simple text and we {testfunc(20)} are happy ";
$newText = preg_replace_callback("/\{testfunc\((\d+)\)\}/","testfunc",$text);

echo $text."\n";
echo $newText."\n";
?>

This should work, using string concatenation:

$text = "Simple text " . testfunc(1) . " and next simple text and we " . testfunc(20) . " are happy ";

$text = "Simple text ".testfunc(1)." and next simple text and we ".testfunc(20)." are happy ";

As normal why not try with,

$text = "Simple text ".testfunc(1)." and next simple text and we ".testfunc(20)." are happy ";
