    }
}

I and not able decode

"categorySpecificInfoV1": {
  "keySpecs": [
    "Passport Holder",
    "Passport Wallet"
  ],

I have tried json_decode. This gives error

Warning: json_decode() expects parameter 1 to be string, array given.

 $keySpecs=$product['categorySpecificInfoV1']['keySpecs'];
 $ar = json_decode($keySpecs,true);

I am new to PHP, how can I print the keyspecs from keyspecs array?

foreach($product['categorySpecificInfoV1']['keySpecs'] as $spec) { echo $spec; }? (depending on what product is in your example). — Jonnix

The warning is pretty clear. You need to pass the entire string you obtained from Flipkart into the json_decode() function.

See Documentation

$ar = json_decode($flipkart_result, true);  
print_r($ar); //to check the array.
print_r($ar['categorySpecificInfoV1']['keySpecs']);

This should do. Post more information if this does not help.

The warning also clearly indicates it is an array. Doing an echo of an array will produce a notice Array to string conversion.

Oh yea, my bad. Didn't see what was inside keySpecs. Let me edit

Swakeert Jain Over a year ago

if it is again saying that did you simply try to print keySpecs: print_r($keySpecs). Otherwise please provide more information about the product and keySpecs variable. Use var_dump($product) and var_dump($keySpecs) and put their results in your question
