Question

I am trying to use preg_replace function to parse this table in a Html page :

Tuition.    $13,140   $13,167    $13,167    
Books       $996      $1,176     $1,176

Because of table tags I got “Unknown modifier ‘t‘ ” error and I changed ‘/ /‘ with ‘~ ~‘.

Still I have problem, the function is not changing the text. I think the problem with ‘$‘ dollars sign in the text, how can I skip it? I tried to do but I couldn’t.

Here is my code :

$price = $html->find('div[id=divctl00_cphCollegeNavBody_ucInstitutionMain_ctl00] table[class=tabular]');

        $price1=$price[0];
        $show=$price1;

        $ch="~".$show->children(1)->children(0)->children(1)."~";
        $show=preg_replace($ch,' ',$show, 1);

Thanks

try this : $show=preg_replace(str_replace('$','\$',$ch),' ',$show, 1);
If you can’t use preg_quote and have multiple escape ( in this case $ is your problem), you could put your special character in an array and filter from it.
