count of array elements in php - php

Question

I m trying to display no of elements in an array,but its showing 1 when i m trying to print the count
<?php
if(!$xml=simplexml_load_file('sunglasses.xml')){
trigger_error('Error reading XML file',E_USER_ERROR);
}
$array1=array();
foreach($xml as $syn)
{
for($i=0;$i<count($syn->productId);$i++)
{
$array1=$syn->productId;
}
}
echo count($array1, COUNT_RECURSIVE);
?>
There are 10 products in the xml file.So i want the count to be 10,but its printing only 1.
Please tell me whats wrong in the code.

Answer 1

Your formatting of code is horrible.
And yes, there might be 10 elements in the xml, but there is only one in $array1 because only the last assignment is present. You never told to $array1 to push values into the array, despite the fact you declared it as array. Assignation process = does not push values, if explicitly not called via array_push() or [] syntax.
$array1[] = $syn->productId;
Should work.
You should have tested the result at least. var_dump()'ing the $array1 will give you result of only one value - the last value, and you would be able to understand that something is wrong.

Following Change in code will resolved your issue.
<?php
if(!$xml=simplexml_load_file('sunglasses.xml')){
trigger_error('Error reading XML file',E_USER_ERROR);
}
$array1=array();
foreach($xml as $syn)
{
for($i=0;$i<count($syn->productId);$i++)
{
// here need to add the result in array. not to assign value directly to array object.
$array1[] = $syn->productId;
}
}
echo count($array1, COUNT_RECURSIVE);
?>
