Allrigh!
I have a highlighting function that is suppose to highligh certain C# keywords. But when it comes to words like 'if', 'is', 'do' and other small words, they can be found in other words, such as infinity, nifty and doh, so I want to be able to find ONLY 'if', 'is', 'in', etc.
Problem is, this won't work:
CODE
$sumstr = preg_replace('#\bin\b#', '<span class="blueBold">in</span', $sumstr);
$sumstr = preg_replace('#\bif\b#', '<span class="blueBold">if</span', $sumstr);
$sumstr = preg_replace('#\bis\b#', '<span class="blueBold">is</span', $sumstr);
It will work for the first one, but the rest won't work, and I'll lose alot of blankspaces in the text.
And if I do this:
CODE
$var = '#\bif\b#';
$sumstr = preg_replace($var, '<span class="blueBold">'.$var.'</span', $sumstr);
the 'if' in the text will be blue, but will also be 'bifb'. So it it gets blue and bold, but somehow the b's are added!
