php - Pass a string as an argument -

i have string have grepped out of php file, arguments passed function, var_dump of string looks this

'foo bar', ['name' => 'john, smith'] 

and do, pass function 2 arguments. if there wasn't going chance of , in array explode string , pass 2 arguments function. can't , need parse string properly.

i can around calling eval.

eval("myfunction({$string});"); 

which work, using eval "risky". there native method pass string separate array of arguments pass function?

i can't run other php file, or change code of it, want grep out arguments (which have done) , pass these arguments own function.

edit:

so string greped changed, code need handle ways of writing php arguments (no spaces after ',', or ' or "). string , array, extracted text.

so need support things like;

"foo",['name' => 'john, smith'] "foo",[] "foo, bar", [1,2 ,3] 

sort of reverse var_export... var_import :)

so, seems best way might use eval... code "trusted" still feels dirty way it, , thought there method parse_str or parse_url.

edit 2:

so basically, twofiles. a.txt opened , regex grabs params in function. file b.php runs regex, , needs handle string pass different function.

a.txt can't changed php file. need run code. (eval works above).

file a.txt  <?php    ... ...    $result = resetresult('foo bar', ['name' => 'john, smith']);    .. ...  ?>   file b.php  <?php     $filecontents = file_get_contents('a.txt');     preg_match_all('/resultresult\((.*?)\)/', $filecontents, $matches);     foreach($matches[1] $args) {       // args = 'foo bar', ['name' => 'john, smith'] string.        // need split args 'foo bar' can passed first argument, , array second argument..       somefunction($args[0], $args[1]);      } 

i did best, i'm still @ beginning php. there no official function convert "array string" array, tried workaround json_decode().

here code , fiddle

<? function get_string_between($string, $start, $end){     $string = " ".$string;     $ini = strpos($string,$start);     if ($ini == 0) return "";     $ini += strlen($start);     $len = strpos($string,$end,$ini) - $ini;     return substr($string,$ini,$len); }  $original = "'foo, bar', ['name' => 'john, smith' , 'anotherkey' => 'another value']"; $str = get_string_between($original, "'", "'"); $arr = get_string_between($original, "[", "]"); $arr = json_decode(str_replace(' => ',':',str_replace('\'','"','{'.$arr.'}')), true); var_dump($str); print_r($arr); ?> 

output

string(8) "foo, bar" array (     [name] => john, smith     [anotherkey] => value ) 

then call yourfunc($str,$arr).

of course code improved, it's start. there problem if array value contains =>, should fixed.

p.s.: get_string_between() taken here.
