[Solved] Automatically replace the first & with a ? question mark. - wolfgang1983 - 04-05-2018
I have this code below which generates a query string for my url.
But I would like to know is there away that it could automatically replace the first & with a ? question mark.
PHP Code:
$url = '';
if ($this->input->get('directory')) {
$pos = strrpos($this->input->get('directory'), '/');
if ($pos) {
$url .= '&directory=' . urlencode(substr($this->input->get('directory'), 0, $pos));
}
}
if ($this->input->get('target')) {
$url .= '&target=' . $this->input->get('target');
}
if ($this->input->get('thumb')) {
$url .= '&thumb=' . $this->input->get('thumb');
}
$data['parent'] = base_url('image_manager' . $url);

Thanks to all who helped working solution
PHP Code:
$find = '&';
$replace = '?';
$result = preg_replace("/$find/", $replace, $url, 1);
echo $result;
PHP Code:
$url = '';
if ($this->input->get('directory')) {
$pos = strrpos($this->input->get('directory'), '/');
if ($pos) {
$url .= '&directory=' . substr($this->input->get('directory'), 0, $pos);
}
}
if ($this->input->get('target')) {
$url .= '&target=' . $this->input->get('target');
}
if ($this->input->get('thumb')) {
$url .= '&thumb=' . $this->input->get('thumb');
}
$data['parent'] = base_url('image_manager' . $url);
