how to substr last ending space?

[Anon]

Hi,

Substr or substr_replace or something else to replace the last ending space in each item?

$str is generated by ($txt=explode "\n", $list), but have ending space in each item like 'author ', but I hope it is like 'author'.

$sub = substr($str, 0, -1) is not working.

thanks for your input,

$txt = preg_replace("/(.*)/e", "trim('\1')", $txt);

• or -

for($i = 0, $count = sizeof($txt); $i < $count; ++$i)
{
$txt[$i] = trim($txt[$i]);
}

Hi,

Thanks so much, $txt[$i] = trim($txt[$i]) works great.
