php - How To Regex Search and Replace array_key_exists with isset? -

whats best way regex search , replace instances of array_key_exists() more efficient isset()? please, no donald knuth quotes regarding optimizations , yes, i'm aware of differences between 2 functions.

this i'm using in netbeans search , replace:

• search for:

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

• replace with:

  isset($2['$1']) 

it works , changing this:

array_key_exists('my_key',$my_array) 

to

isset($my_array['my_key']) 

but doesn't pick instances this:

array_key_exists($my_key,$my_array) 

not elegant solution, adding current regex find both types of search criteria.

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