Error reading Json array using foreach loop - json

Question

I'm sending an serialize ajax post request.
$.ajax({
type: 'post',
url: 'js/json.php',
data:{
'a': 'JRNLHDR-SAVE',
'formdata':$(_tr).find('[name^="formdata_jrnlhdr"]').serialize(),
},
success: function (data){
console.log(data);
},
error: function (er){
console.log(er);
}
});
Json data is correct
Array
(
[formdata_jrnlhdr] => Array
(
[153] => Array
(
[txid] => 153
[reference] => PH/21/JB0161
[description] => Adjustment Entry
)
)
)
I'm trying to read the data in php but it giving an error
Undefined index: txid, reference and description
foreach($journal_entry as $keys => $val){
print_r( $val['txid'] . $val['reference'] . $val['description'] );
}

Answer 1

That fault, because you miss your child array [153] .. and you call $keys in foreach, but still not using it.
Try this:
foreach($journal_entry as $val){
print_r( $val[153]['txid'] . $val[153]['reference'] . $val[153]['description'] );
}
Edit...
For dynamic array index, use this:
foreach($journal_entry as $key => $val){
print_r( $val[$key]['txid'] . $val[$key]['reference'] . $val[$key]['description'] );
}
