What version of PHP are you using? if it's at least version 4, you can use foreach instead of each... so the syntax would look like:

Code: Select all

if(is_array($tc['one_res'])){
    foreach($tc['one_res'] as $val)
    {
        $report[$val['brand_name']][$val['material_no']]['one_qty']=$val['qtysum']; 
    }
}
else{
    echo "Could not iterate results, because tc is not an array!";
    print_r($tc); // Print what it is so you can figure out why it wasn't an array
}

you have to have modifiers with preg_match. put a # at the beginning of your pattern and a # at the end of your pattern. that should do the trick ;)

ok 1st thing i will say is perdy please use the php / code tags when posting code. it makes it much easier to read.

second, i don't know much about regular expressions (preg_match stuff) but why not just use strpos?

Code: Select all

$pattern = '**SPEAKERNAME**';

if (false !== strpos($source, $pattern))
{
    echo 'a match was found';
}
else
{
    echo 'no matches found';
}
its much easier if you are just looking for a string and not a pattern. also note how perdy that code looks :P
