Question

I try to use var_dump on command line with phpsh in order to get debugging information about some variable. But the variable contains a very deeply nested data structure. Therefore, using the default var_dump outputs too much information.

I want to limit the depth level of var_dump output. I found that XDebug’s var_dump implementation allows depth limiting as described here: http://www.giorgiosironi.com/2009/07/how-to-stop-getting-megabytes-of-text.html

Unfortunately, I couldn’t make this work neither. I don’t know yet the reason for this. I am looking for if there are any alternative var_dump implementations to try.

Check this :

function print_array($array,$depth=1,$indentation=0){
    if (is_array($array)){
                    echo "Array(\n";
        foreach ($array as $key=>$value){
            if(is_array($value)){
                if($depth <= 0){
                    echo "max depth reached.";
                }
                else{
                    for($i=0;$i<$indentation;$i++){
                        echo "&nbsp;&nbsp;&nbsp;&nbsp;";
                    }
                    echo $key."=Array(";
                    print_array($value,$depth-1,$indentation+1);
                    for($i=0;$i<$indentation;$i++){
                        echo "&nbsp;&nbsp;&nbsp;&nbsp;";
                    }
                    echo ");";
                }
            }
            else{
                for($i=0;$i<$indentation;$i++){
                    echo "&nbsp;&nbsp;&nbsp;&nbsp;";
                }
                echo $key."=>".$value."\n";
            }
        }
                    echo ");\n";
    }
    else{
        echo "It is not an array\n";
    }
}
