Question

I have a long xml data file with 500+ items in it, it comes in this form:

<?xml version="1.0" encoding="ISO-8859-1"?>
<CATALOG>
<ITEM>
    <TITLE>ITEM name</TITLE>
    <TYPE>"T1", "T2", "T3" </TYPE>
    <DESCIPTION>DESCIPTIONiliate Page CPM</DESCIPTION>
    <PRICE>PRICE</PRICE>
    <ITEM>http://mysite.com/item-link</ITEM>
</ITEM>
</CATALOG>

and I use the following code in the php page to import data from the xml file:

<?php
$ITEMSS = new SimpleXMLElement('ITEMS.xml', null, true);

echo <<<EOF
<table width="100%" align="center" border="1" bordercolor="#0099ff" cellpadding="1" cellspacing="0">

    <tr>
            <th bgcolor="#66ccff"><span class="style4">ITEM Name</span></th>
            <th bgcolor="#66ccff"><span class="style4">item TYPE </span></th>
            <th bgcolor="#66ccff"><span class="style4">item DESCIPTION </span></th>
            <th bgcolor="#66ccff"><span class="style4">item PRICE</span></th>
            <th bgcolor="#66ccff"><span class="style4">link to item</span></th>
    </tr>

EOF;
foreach($ITEMSS as $ITEMS) // loop through our DATAS
{
    echo <<<EOF
    <tr height="30" align=middle>
            <td><a href="{$ITEMS->ITEM}" target="_blank"><span class="STYLE7">{$ITEMS->TITLE}</span></a></td>
            <td><span class="STYLE8">{$ITEMS->TYPE}</span></td>
            <td><span class="STYLE8">{$ITEMS->DESCIPTION}</span></td>
            <td><span class="STYLE8">{$ITEMS->PRICE}</span></td>
            <td><a href="{$ITEMS->ITEM}" target="_blank"><B><span class="STYLE7">cHECK IT OUT</span></B></a></td>
    </tr>

EOF;
}
echo '</table>';
?>

in the TYPE I have different values like:

    <TYPE>"T1", "T2", "T3" </TYPE>
    <TYPE>"T1", "T4", "T6" </TYPE>
    <TYPE>"T1", "T8", "T1" </TYPE>

each item may have diffrent TYPE values

I need to add an “if” statement in the loop to select only some data if a value is in array of TYPE somethink like:

foreach($ITEMSS as $ITEMS) // loop through our DATAS
{
$options = array($ITEMS->TYPE);

if (in_array("T1", $options))

   { echo <<<EOF
    <tr height="30" align=middle>
            <td><a href="{$ITEMS->ITEM}" target="_blank"><span class="STYLE7">{$ITEMS->TITLE}</span></a></td>
            <td><span class="STYLE8">{$ITEMS->TYPE}</span></td>
            <td><span class="STYLE8">{$ITEMS->DESCIPTION}</span></td>
            <td><span class="STYLE8">{$ITEMS->PRICE}</span></td>
            <td><a href="{$ITEMS->ITEM}" target="_blank"><B><span class="STYLE7">cHECK IT OUT</span></B></a></td>
    </tr>


EOF;
}

}

but even if the value I look for is in the array , it shows nothing!.

So how can I use if in array statement in this case?

Answer 1

The problem comes from your preparation of the $options variable, try initiating it like so;

PHP >= 5.3

$options = array_map(function($type) {
    return str_replace('"', '', trim($type));
}, explode(',', $ITEMS->TYPE));

PHP < 5.3 (put the function out of the loop :D)

function parseTypes($type) {
    return str_replace('"', '', trim($type));
}

$options = array_map(parseTypes, explode(',', $ITEMS->TYPE));

That should explode the types into an array, remove the quotes and trim extra spaces.
