what is the mean of + in front of a line in php
diff, php
Solution
It has no meaning, it is superfluous. You can write the exact same statement without the plus:
$array['key1']['key2'] = "value"
If you have that from a unified `diff` file, it means that this line was added. So that plus is not PHP code, it is a marker for that line in the diff/patch. The other marker is minus `-` for removing a line.
Problem
I have a question about syntax in php. What is the mean of + in following line? Thanks! ``` +$array['key1']['key2'] = "value" ```
