Strange <pre> format error

[wepnop]

Im creating a function for executing a system command. The idea is to show the command return. I use pre to show it, so i created a general function iPre that echos a string with that tag.

 

The problem is that this code dont work.

 

function compComando($com) {
return escapeshellcmd($com);
}

function ejecComando($com) {

$return = passthru(compComando($com));
if ($return) {
	return $return;
}
else {
		pe();
}
}

function iPre($txt) {
echo '<pre>';
echo $txt;
echo '</pre>';
}


iPre(ejecComando('dir C:'));

 

But if i call this simple code it works. Why?

 

echo '<pre>';
echo ejecComando('dir C:');
echo '</pre>';

 

Here its shown well formatted, in the other no. I suppose thats something relating passing the string to the function...?

are your sure

ejecComando('dir C:')

returns a string?

[wepnop]

are your sure

ejecComando('dir C:')

returns a string?

 

Yes. passthru returns the full command output if it goes well. And its returned and no error pe() raised.

 

I tried using casting (string) to force it and it still didnt work.

passthru() does not return anything.  Check the manual.  You will need exec() with the output arg or use back ticks `.
