In reference to the discussion at: , where suggestions mainly revolved around JavaScript.
Is there a specific function in PHP that can be utilized to address the issue described below and ensure that the output is valid JSON? Please note that using front end (JS) solutions is not feasible in this scenario. The problem seems to stem from the unquoted number leading into the array. Unfortunately, fixing the source directly is not an option for me.

Edit: Basic functions like json encode/decode do not seem to work here. It appears that the data has undergone multiple transformations before it can even be processed by PHP.
To clarify, the following snippet illustrates the preprocessing steps that occur prior to dealing with the mentioned issue:
$instring = false;
$inescape = false;
$lastchar = '';
$output = "";
for ( $x=0; $x<strlen( $sourcejson ); $x++ ) {
$char = substr( $sourcejson, $x, 1 );
//toss unnecessary whitespace
if ( !$instring && ( preg_match( '/\s/', $char ) ) ) {
continue;
}
//handle strings
if ( $instring ) {
if ( $inescape ) {
$output .= $char;
$inescape = false;
} else if ( $char == '\\' ) {
$output .= $char;
$inescape = true;
} else if ( $char == '"' ) {
$output .= $char;
$instring = false;
} else {
$output .= $char;
}
$lastchar = $char;
continue;
}
switch ( $char ) {
case '"':
$output .= $char;
$instring = true;
break;
case ',':
if ( $lastchar == ',' || $lastchar == '[' || $lastchar == '{' ) {
$output .= 'null';
}
$output .= $char;
break;
case ']':
case '}':
if ( $lastchar == ',' ) {
$output .= 'null';
}
$output .= $char;
break;
default:
$output .= $char;
break;
}
$lastchar = $char;
}
