I hope that your input is in single string.So do like below:-

<?php

$string = '["0:12:23", 0.000000],["0:12:43", 0.000000],["0:13:03", 0.000000]'; // i assume it's a single string
preg_match_all('/\d:\d{2}:\d{2}/',$string,$matches);

print_r($matches);

Output:- https://eval.in/895248

Or as @deceze said use json_decode("[$string]") like below:-

<?php
  $string = '["0:12:23", 0.000000],["0:12:43", 0.000000],["0:13:03", 0.000000]';
  $string_array=json_decode("[$string]");
  $time_array = array_column($string_array,0);
  print_r($time_array);
?>

Output:- https://eval.in/895251

Reference:-

preg_match_all()

json_decode()

array_column()

is print_r($matches[0]) returns the first time value?

@Psl no. it will return array of all time

You can do:- $final_time_array = $matches[0]; echo $final_time_array[0];

You can use json_decode to convert it into array structure.and use foreach loop to filter out .try below,

<?php
$string = '["0:12:23", 0.000000],["0:12:43", 0.000000],["0:13:03", 0.000000]';
$string_to_array=json_decode("[$string]");
foreach($string_to_array as $values){  
print_r($values[0]); 
}
?>
