在PHP中将assac转换为字符串

Question

I'm trying to convert JSON-Object like [{"text":"hallo"},{"text":"hello"}] into a string which should look like "hallo hello".

At the moment, I'm decoding the JSON-Object with json_decode($words, true);

The result is being sent to a function than, which looks like:

function assocToString($assoc)
{
    $ergString="";

    foreach($assoc as $key => $value)
    {
        if($ergString=="")
        {
            $ergString = $value;
        }
        else
        {
            $ergString .= $value;
        }

        $ergString .= " ";
    }

    return $ergString;
}

I get errors like "Array to string conversion" all the time, maybe someone of you could please as be as kind as to help me out?

This apparently mean that your array was an multi-dimension array. Try to put another foreach loop inside the existing one.

Use vardump or print_r to check how does the current data store in $assoc look like

foreach($assoc as $key)
{
   foreach($key as $value){
    if($ergString=="")
    {
        $ergString = $value;
    }
    else
    {
        $ergString .= $value;
    }

    $ergString .= " ";
   }
}
