php explode to split and combine reverse string

Question

text left - text right

How to swap right to left using php? str pos is not so good because the pattern is not always fix. It could be somethingleft-somethingright or more left text here - right

The result that I want should look like text right - text left

tried explode() but it isn't always single character at the left or right side.

Instead of considering delimiter as "-", you can consider the delimiter as " - " (notice the spaces). — sampathsris

Simply can use explode(). Example here

$str = "text left - text right";
$exp = explode('-', $str);
$newStr = trim($exp[1]) . ' - ' . trim($exp[0]);
echo $newStr;

echo trim( implode(' - ', array_reverse(explode('-', 'text left - text right'))));

It's a messy one liner but great for ability to use multiple delimiters

$strArr = preg_split(' - ','text left - text right');
$newStr = $strArr[1] . ' - ' . $strArr[0];

Split the string using the pattern ' - '. Then concatenate a new string by placing the right value $strArr[0] at the beginning of the concatenated string followed by the ' - ' pattern and finally the first half of the string $strArr[0].

A simple explode will suffice, but until he pastes code, I'm not going to spoon feed him

explode() might not see the spaces
