Description:
------------
when dealing with a complex array that had nested levels with either 0
based index arrays or string based keys, i had to recursively parse each
nested level to transform it in another layout. the parsing method used
foreach regardless if it was a 0 based index or a string based one and
at some levels that had a key 'id' i wanted to get rid of that. so i was
testing if($key!='id') but that brakes the foreach in case of a 0 based
indexed array. the solution was to add if(is_int($key) || $key!='id').
my impression is that something is happening when $key is an int in the
case of 0 based index array and is compared to a string.
i have attached in the code box a smaller code that seems to show the
problem by not echoing the first element of the array. if needed i will
try to recreate the more complex code with the recursive parser.
Reproduce code:
---------------
<?php
$ar=array('a','b','c','d');
foreach($ar as $key => $value)
{
echo 'ar['.$key.']='.$value.'<br>';
}
echo '<br><br>';
//should work but it doesn't
foreach($ar as $key => $value)
{
if($key!='whatever string')
{
echo 'ar['.$key.']='.$value.'<br>';
}
}
echo '<br><br>';
//this works
foreach($ar as $key => $value)
{
if(is_int($key) || $key!='whatever string')
{
echo 'ar['.$key.']='.$value.'<br>';
}
}
?>
Expected result:
----------------
ar[0]=a
ar[1]=b
ar[2]=c
ar[3]=d
ar[0]=a
ar[1]=b
ar[2]=c
ar[3]=d
ar[0]=a
ar[1]=b
ar[2]=c
ar[3]=d
Actual result:
--------------
ar[0]=a
ar[1]=b
ar[2]=c
ar[3]=d
ar[1]=b
ar[2]=c
ar[3]=d
ar[0]=a
ar[1]=b
ar[2]=c
ar[3]=d
