PHP form submit not returning all values from the form

I have a form with n numbers of data.When i click submits on request ($_REQUEST) i could receive only 1st 50 data?The form field inputs are in array.What could be the issue?Can anyone help me to resolve the issue?

Sample code:

<div class="DTE_Field_Type_text DTE_Field_Name_Branch_name Phone">
   <label data-dte-e="label" class="col-sm-2 control-label">
      Branch Name:
      <div data-dte-e="msg-label" class="DTE_Label_Info"></div>
   </label>
   <div data-dte-e="input" class="col-sm-4">
      <input value="Leeds Vicar Ln" name="branch_name_48[]" placeholder="Branch Name" id="DTE_Field_branch_name_48" class="form-control-occupancy" required="" type="text">
      <div style="display: none;" data-dte-e="msg-error" class="help-block"></div>
      <div data-dte-e="msg-message" class="help-block"></div>
      <div data-dte-e="msg-info" class="help-block"></div>
   </div>
   <label data-dte-e="label" class="col-sm-2 control-label">
      Branch Address:
      <div data-dte-e="msg-label" class="DTE_Label_Info"></div>
   </label>
   <div data-dte-e="input" class="col-sm-4">
      <textarea name="branch_addr_48[]" placeholder="Branch Address" id="DTE_Field_hq_addr_48" class="form-control-occupancy"></textarea>
      <div style="display: none;" data-dte-e="msg-error" class="help-block"></div>
      <div data-dte-e="msg-message" class="help-block"></div>
      <div data-dte-e="msg-info" class="help-block"></div>
   </div>
</div>

<input class="btn btn-primary" id="savenext" name="save" value="Save" type="submit">

Branch Name: Branch Address:

The form has more fields.i.e branch_addr_100 and so on.From this form i could recieve only branch_addr_49. How could i retrieve all 100 records.?
