php array( ) key without quotes [duplicate]

Question

I have a project with many array() key without quotes

$ary = array( name => "Smith" );

Any way to convert its key with quote?

$ary = array( 'name' => "Smith" );

I know codes like

$ary[name] = "Smith" ; // can change to $ary['name'] using editor with regexp

But the problem if it is coded this way

$ary = array( name => "Smith" ); // or worse $ary = array( name => "Smith", class => "2A" );

How to use regexp to add quote to the array key?

This project has thousands of php files. Any body had experience this and what do you recommend to search and replace all php files. Thank you.

how did you have thousands of invalid files to start with ?!? — user557846

@Dagon it happens when error_reporting value was set to hide notices and above for a long time. I dealt myself with this kind of stuff when I lifted this setting. I suppose the OP has the similar case — Ruslan Bes

You should use a text editor which supports find and replace option using a REGEX.

Refer to this: How to fix associative array keys that lack single quotation marks in multiple files

It looks like that answer fixes only the $ary[name] = "Smith" ; stuff but not the other variations

You will need two regexp passes with find/replace

The first one that replaces $ary[name] = "Smith" is listed here.

Match: (\$[a-zA-Z0-9]+\[)([^\]]+)\]

Replace: \1'\2']

The second one targets the name => "Smith" case:

Match: ([a-zA-Z0-9]+)\s*=>

Replace: '\1' =>

To mass replace this you can use vim as described here, any mature PHP IDE like NuSphere or PhpStorm or many Text editors (Notepad++ or SublimeText) - just check the menu "Search" in them. Be sure the files you are modifying are under the version control so that you can rollback any changes that you don't want.

Also if you keys may include underscores use [a-zA-Z0-9_] instead of [a-zA-Z0-9] in both regexps.
