如何计算PHP中的每个字段

Question

I have the below code:

function cat_fields($fields)
{
global $cfg;
$fields['cat_furl'] = str_replace('%cat_safename%', $fields['cat_safename'], $cfg->getVar('urlformat_cat'));
$fields['cat_furl'] = $cfg->getVar('site_url') . str_replace('{cat_safename}', $fields['cat_safename'], $fields['cat_furl']);
$fields['cat_flink'] = '<a id="a'  . count($fields) .  '" href="' . $fields['cat_furl'] . '" title="' . $fields['cat_title'] . '">' . $fields['cat_name'] . '</a>';
return $fields;
}

And i am trying to count each field of $fields['cat_flink'] = '<a id="a' . count($fields) . '" I tried with id="a' . count($fields) . '" but it's returning the total number of field instead of counting them. How can i count them EACH .

Should be

<a id="a1"....>
<a id="a2"....>

Instead it's echoing me

<a id="15"....>
<a id="15"....>
..... and so on

Please help me on this matter.

Answer 1

You're trying to count all the fields in your array; Quoted from the PHP Manual :

Counts all elements in an array, or something in an object.

To get indices (ie the numbers you're looking for), you will have to set a starting number and loop over all your fields until you've got them all, and increment that number everytime your walk through the loop.

Your method however, seems to be for only one iteration, which means you would have to store your number elsewhere. A good way to do this would be adding the number as a parameter to your function:

function cat_fields($fields, $number)
{
global $cfg;
$fields['cat_furl'] = str_replace('%cat_safename%', $fields['cat_safename'], $cfg->getVar('urlformat_cat'));
$fields['cat_furl'] = $cfg->getVar('site_url') . str_replace('{cat_safename}', $fields['cat_safename'], $fields['cat_furl']);
$fields['cat_flink'] = '<a id="a'  . $number .  '" href="' . $fields['cat_furl'] . '" title="' . $fields['cat_title'] . '">' . $fields['cat_name'] . '</a>';
return $fields;
}

Having done that you should edit the loop (I presume) you're using to call the function multiple times:

for ($i = 1; $i < count($yourArray); $i++) {
    // code
    $foo = cat_fields($yourArray, $i);
    // more code
}

Hope that helps.

EDIT :

I've edited the pastebin from lines 131-141:

if(($rs = $db->execute($sql)) && (!$rs->EOF))
{
    $i = 1;
    while(!$rs->EOF)
    {
        $rs->fields = seoscripts_prepare_cat_fields($rs->fields, $i);

        $tpl->assign_array_d('tool_category_row', $rs->fields);
        $tpl->parse_d('tool_category_row');
        $rs->MoveNext();
        $i += 1;
    }
}

Counting like that count($fields) returns the numbers of fields you have you need to add a integer like i=0;

and increase it i++;

Try this

function cat_fields($fields)
{
global $cfg;
$fields['cat_furl'] = str_replace('%cat_safename%', $fields['cat_safename'], $cfg->getVar('urlformat_cat'));
$fields['cat_furl'] = $cfg->getVar('site_url') . str_replace('{cat_safename}', $fields['cat_safename'], $fields['cat_furl']);
$str = '';
$i = 0;
foreach($fields as $field)
{
   $str . = '<a id="a'  . $i .  '" href="' . $fields['cat_furl'] . '" title="' . $fields['cat_title'] . '">' . $fields['cat_name'] . '</a>';
   $i++;
}
$fields['cat_flink'] = $str;
return $fields;
}

Answer 4

Try this

    function cat_fields($fields)
        {
        global $cfg;
        $fields['cat_furl'] = str_replace('%cat_safename%', $fields['cat_safename'], $cfg->getVar('urlformat_cat'));
        $fields['cat_furl'] = $cfg->getVar('site_url') . str_replace('{cat_safename}', $fields['cat_safename'], $fields['cat_furl']);
$i=0;
        foreach($fields as $field)
        {
           $fields['cat_flink'] = '<a id="a'.$i.'" href="' . $field['cat_furl'] . '" title="' . $field['cat_title'] . '">' . $field['cat_name'] . '</a>';
i++;
        }
        return $fields;
        }

Answer 5

if you are counting an array then

echo count($array);

will give the count of every element in the array.
