thanks to what I found from the comments here I'm attaching a pair of functions that will
generate an object structure identical to json_decode from PHP > 5.2 for those still on older PHP
versions - based on the function from www at walidator dot info but returning an object rather then
arrays. The intent is a direct drop-in replacement for the new built-in decoder.
function processJsonObj($pSuffix=0, $json){
$vInQuote = false;
$vNextSuffix = $pSuffix;
$vPreCode = '';
$vTempJSON = '$oJson'.$pSuffix.' = new stdClass();'."\n";
$vTempJSON.= '$oJson'.$pSuffix.'->';
$vOIdx = 1;
$vAIdx = 0;
for($i=0; $i < strlen($json); $i++){
if(!$vInQuote){
if($vOIdx == 1){
if($json[$i] == '{') {
$vNextSuffix++;
$vTempJSON.= '$oJson'.$vNextSuffix;
$vPreCode .= '$oJson'. $vNextSuffix.' =
processJsonObj('.$vNextSuffix.',\'';
$vOIdx++;
}elseif($json[$i] == '[') {
$vTempJSON .= ' array(';
$vAIdx++;
}elseif($json[$i] == ']'){
$vTempJSON .= ')';
$vAIdx--;
}elseif(($vAIdx == 0) && ($json[$i] == ',')){
$vTempJSON .=
';'."\n".'$oJson'.$pSuffix.'->';
}elseif($json[$i] == ':'){
$vTempJSON .= ' = ';
}else{
$vTempJSON .= $json[$i];
}
}else{
if($json[$i] == '{'){
$vOIdx++;
$vPreCode .= $json[$i];
}elseif($json[$i] == '}'){
$vOIdx--;
if($vOIdx == 1){
$vPreCode .= '\');'."\n";
}else{
$vPreCode .= $json[$i];
}
}else{
$vPreCode .= $json[$i];
}
}
}else{
$vTempJSON .= $json[$i];
}
if(($vOIdx == 1) && ($json[$i] == '"')){
$vInQuote = !$vInQuote;
}
}
if(preg_match_all('/\-\>?("[^=]*")/', $vTempJSON, $vRegs,
PREG_SET_ORDER)){
foreach($vRegs as $vKey => $vMatch){
$vTempJSON = str_replace($vMatch[1],
trim(str_replace('"','',$vMatch[1])),$vTempJSON);
}
}
$vFinalCode = $vPreCode."\n".$vTempJSON.';';
eval($vFinalCode);
$vOutput = 'oJson'.$pSuffix;
return $$vOutput;
}
