Question

I need to practically generate a .PHP file using a PHP script or PHP command. The file generate will contain the following code:

<?php
class TextToSpeech {
    public $mp3data;
    function __construct($text="") {
        $text = trim($text);
        if(!empty($text)) {
            $text = urlencode($text);
            $lang_en="http://translate.google.com/translate_tts?tl=en&q={$text}";
            $lang_ro="http://translate.google.com/translate_tts?tl=ro&q={$text}";
            $lang_fr="http://translate.google.com/translate_tts?tl=fr&q={$text}";
            $language=$lang_en;
            $this->mp3data = file_get_contents($language);
        }
    }

    function setText($text) {
        $text = trim($text);
        if(!empty($text)) {
            $text = urlencode($text);
            $en="http://translate.google.com/translate_tts?tl=en&q={$text}";
            $ro="http://translate.google.com/translate_tts?tl=ro&q={$text}";
            $fr="http://translate.google.com/translate_tts?tl=fr&q={$text}";
            $lang=$en;
            $this->mp3data = file_get_contents($lang);
            return  $this->mp3data;
        } else { return false; }
    }

    function saveToFile($filename) {
        $filename = trim($filename);
        if(!empty($filename)) {
            return file_put_contents($filename,$this->mp3data);
        } else { return false; }
    }
}
?>

I want to do this because I want to have multiple choices regarding the language:

$language=$lang_en;

and

$lang=$en;

Not sure what your question is here. Generating a PHP file is no different than generating any other kind of file. Build a string of the source code you want to write, then a simple file_put_contents('filename.php', $contents); will do the trick.

Edit: Where are $en and $lang_en coming from? Also, could these not be passed as parameters to the function? Why must they be hard-coded?

$contents = '
<?php
   // your PHP here

';

file_put_contents('filename.php', $contents);

You may also want to read up on heredocs for large blocks of text, but unfortunately those will replace your variables unless you escape them all with a backslash.
