I am trying to find a way to replace the $_POST['INPUT'] by $this->input->post('INPUT') of codeigniter , in my editor phpstorm , using replace with the regex option enabled.
input would be retained and I would just replace the $_post variables with the codeigniter function throughout the file.
Use this regex to capture the characters you want by separating them into 2 groups.
\$_(.*?)\['(.*?)'\]
In the substitution field use:
$this->\L$2->$1\('\U$2\')
Explanation:
The first regex will capture the values you want by separating the wordpost into group 1 and the word input into group 2
After this, in the substitution field, they will be used by referencing as the first catch group and for the second, resulting in
$this->input->post('INPUT')
It is worth remembering that some regex flavors do not allow the use of modifiers in replacement groups, if this is the case, you can change the replacement part to:
$this->input->$1\('$2\')
You can test your regex here
As mentioned by the user who asked in the comments of this response, what solved your problem was:
\$this->input->\L$1\('\L$2\')
