How can I decode json in PHP 5.1?

Question

json_decode function is not part of PHP 5.1, so I cannot use it. Is there any other function for this version?

Answer 1

The Zend framework has Zend_Json. At least it used to a couple of years ago.

You can just pull out the JSON library and use it in a standalone manner.

code

<?php 
if ( !function_exists('json_decode') ){ 
function json_decode($json) 
{  
    // Author: walidator.info 2009 
    $comment = false; 
    $out = '$x='; 

    for ($i=0; $i<strlen($json); $i++) 
    { 
        if (!$comment) 
        { 
            if ($json[$i] == '{' || $json[$i] == '[')        $out .= ' array('; 
            else if ($json[$i] == '}' || $json[$i] == ']')    $out .= ')'; 
            else if ($json[$i] == ':')    $out .= '=>'; 
            else                         $out .= $json[$i];            
        } 
        else $out .= $json[$i]; 
        if ($json[$i] == '"')    $comment = !$comment; 
    } 
    eval($out . ';'); 
    return $x; 
}  
} 
?>
