Function should RETURN:
http://googleads.g.doubleclick.net/pagead/ads?....url=www.prostatecancerguide.net....&ref=...gleason...

Obviously, it will return all the readable parts of the url and omit the garbages.. Thanks guys.

 

you want to cut that text and you do not know how ?

copy here function you use

 

$tok = strtok($webAddress, "1234567890%&=q");
$str='';
$flag_qm=0;
while ($tok !== false) {
echo "Word=$tok<br />";
if($flag_qm==0){
$exp = explode('?',$tok);
echo "Explode=$exp[0]?<br />";
$str=$str . $exp[0] . '?';
$flag_qm=1;
}
$exp = explode('F',$tok);
if(explode('F',$tok)) {
echo "<br />Yes";
}
else {
echo "<br />No";
}
echo "<br />Explode= $exp[1]<br />";
if(exp)
$str=$str.$exp[1] . '.';
$tok = strtok("1234567890%&=/q");
}

 

Can you elaborate more what you want to do ?
