I have a url. I want to parse url. I don't want to get last two value. How can I do?
$str="first-second-11.1268955-15.542383564";
As I wanted
$str="first-second";
I used this code. But I don't want to get - from last value
$arr = explode("-", $str);
for ($a = 0; $a < count($arr) - 2; $a++) {
$reqPage .= $arr[$a] . "-";
}
You can use regular expressions too.Those are patterns used to match character combinations in strings.:
W*((?i)first-second(?-i))\W*
Use the 3rd param of explode() called limit:
$str="first-second-11.1268955-15.542383564";
$arr = explode("-", $str, -2);
$reqPage = implode($arr, "-"); // contains "first-second"
Regex is the fastest way for the string manipulations. Try this.
$str="first-second-11.1268955-15.542383564";
preg_match('/^[a-z]*-{1}[a-z]*/i', $str, $matches);
$match = count($matches) > 0 ? $matches[0] : '';
echo $match;
"If you don't need the power of regular expressions, you can choose faster (albeit simpler) alternatives like explode() or str_split()." php.net/manual/en/function.preg-split.php
substr($reqPage, 0, -1)will remove last character of your string.
