Question

I have this function :

function MakeInput($id, $class) {
    $value = substr($id, 2);
    global $$value;
    echo '<input type="text" id="'.$id.'" name="'.$id.'" class="'.$class.'" value="'.htmlentities($$value,ENT_COMPAT,'UTF-8').'" />';
}

Which do not return but echoes the results.

I’d like to use it as it is into another function:

function ItkMakeMo($NomDebVar) {
$Output = '
    <tr>    
        <td>Test</td>
    </tr>
    <tr>
        <td>'.MakeInput($NomDebVar.'moshj','IntInput').'</td>
    </tr>
';
echo $Output;

}

So this solution doesn’t work, PHP sends the MakeInput output before the “echo $Output”

Answer 1

If for some reason you can’t change MakeInput() or it would take more effort than it’s worth to change it, then you can echo the output directly from ItkMakeMo():

function ItkMakeMo($NomDebVar) {
echo '
    <tr>    
        <td>Test</td>
    </tr>
    <tr>
        <td>';

MakeInput($NomDebVar.'moshj','IntInput');

echo '</td>
    </tr>
';
}

Then the MakeInput() output would be in the right place.

If possible, it’s usually better not to directly output in functions and instead return the output as a string, then you can output it when you call the function.
