Question

I have some numbers, and depending on the number’s value I need to highlight a string which is in a table. The table is not in database.

Does anyone know how to highlight text in php?

Answer 1

PHP won’t “highlight” text, that is done with CSS/HTML. You only use PHP to output the correct HTML.

Something like this:

$my_num = 9;
foreach ($my_array_of_numbers as $num)
{
   // See if $num matches $my_num, if so - add the "highlight"
   // class to the HTML element we're using
   $css_class = ($num == $my_num) ? 'highlight' : '';
   echo '<td class="'.$css_class.'">'.$num.'</td>';
}

Then in your CSS:

.highlight {
    background:yellow;
}

You may also want to consider using javascript for this, which can handle the task after the HTML has already been generated.
