Post JSON object to php using Ajax - php

Question

I am dynamically adding table rows by selecting options from dropdown and then I am trying to send html table rows to php function using ajax as array in json format. However php function does not print all rows in the console log, when I am submitting more than one row. I got the desired output like once or twice. I think I am missing something in the php function. Please check once. If anymore information about the code is required, let me know, I will update.
Javascript:
function storeClgValues() {
var CollegeData= new Array();
$('#collegetable tr').each(function(row, tr){
CollegeData[row]={
"college" : $(tr).find('td:eq(0)').text()
}
});
CollegeData.shift();
return CollegeData;
}
$('#submit').click(function() {
CollegeData=storeClgValues();
CollegeData=$.toJSON(CollegeData);
$.ajax({
type:"POST",
url: '<?php echo base_url();?>ajaxController/insertcollege',
data: "CollegeData=" + CollegeData,
success: function(msg) {
console.log(CollegeData);
console.log(msg);
}
});
});
PHP function in AjaxController class:
public function insertcollege()
{
$data=array();
$data=stripcslashes($_POST['CollegeData']);
$data=json_decode($data, TRUE);
//echo $data[0]['college'].'<br>';
//echo $data[1]['college'].'<br>';
if (is_array($data) || is_object($data))
{
foreach ($data as $key => $item) {
echo $item['college'].'<br>';
}
}
}
Output in console in three tries:
[{"college":"College of Agriculture"}]
College of Agriculture
[{"college":"College of Agriculture"},{"college":"College of Business"}]
College of Agriculture
College of Business
[{"college":"College of Agriculture"},{"college":"College of Business"}, {"college":"College of Comm & Educati"}]
<!--nothing gets printed-->

Try like this...
<?php
$json = '[{"college":"College of Agriculture"},{"college":"College of Business"}, {"college":"College of Comm & Educati"}]';
$data = json_decode($json,TRUE);
//print_r($data);
if (is_array($data) || is_object($data))
{
foreach ($data as $key => $item) {
$output[]=$item['college'].'<br>';
}
}
echo json_encode($output);
?>
OR
<?php
$json = '[{"college":"College of Agriculture"},{"college":"College of Business"}, {"college":"College of Comm & Educati"}]';
$data = json_decode($json,TRUE);
//print_r($data);
if (is_array($data) || is_object($data))
{
foreach ($data as $key => $item) {
foreach($item as $value){
$output[] = $value."</br>";
}
}
}
echo json_encode($output);
?>
