[FIXED] How To Regex Search and Replace array_key_exists with isset?

Issue

Whats the best way to do a regex search and replace for all instances of array_key_exists() with the more efficient isset()? Please, no Donald Knuth quotes regarding optimizations and yes, I'm aware of the href="https://stackoverflow.com/a/3210982/3306354">differences between the two functions.

This is what I'm currently using in my Netbeans search and replace:

• search for:

  array_key_exists\s*\(\s*'([^']*)'\s*,([^)]*)\) 
  

• replace with:

  isset($2['$1'])
  

it works well , changing this:

array_key_exists('my_key',$my_array)

to

isset($my_array['my_key'])

but doesn't pick up instances like this:

array_key_exists($my_key,$my_array)

Solution

The best I could do was to run a second search and replace to cover the instances that used variables for both arguments:

array_key_exists($my_key,$my_array)

search and replace 2:

• search for:

  array_key_exists\s*\(\s*(\$[^,]*)\s*,([^)]*)\)

• replace with:

  isset($2[$1])
