基本上,我想同时将$city_name
和$ref_name
与str_replace()一起使用,这样如果用户输入其中一个(或两个),则两个都被替换为实际变量形式。
为了更好地说明,这是我目前的代码;
$headlines = array('primary_headline' => $_POST['primary_headline'], 'secondary_headline' => $_POST['secondary_headline'], 'primary_subline' => $_POST['primary_subline'], 'secondary_subtext' => $_POST['secondary_subtext']);
$city_name = "Dallas";
$ref_name = "Facebook";
if(isset($headlines)) {
foreach($headlines as $headline) {
echo(str_replace('$city_name', $city_name, $headline));
}
}
我基本上希望str_replace('$city_name', $city_name, $headline)
成为str_replace('$city_name' AND/OR '$ref_name', $city_name AND/OR $ref_name, $headline)
。
任何答案或评论都将不胜感激!

$searches = array('$city_name', '$ref_name');
$replacements = array($city_name, $ref_name);
echo str_replace($searches, $replacements, $headline);
