Opposite PHP function of strstr to return first part of string, not last

php, string, strstr

Solution

Pass true as the third parameter.

From the manual page you have linked:

string strstr (string $haystack , mixed $needle [, bool $before_needle = false ])

before_needle: If TRUE, strstr() returns the part of the haystack before the first occurrence of the needle (excluding the needle).

Note: This parameter was only added in PHP 5.3. If for some reason you are left with an older version, a combination of `substr()` and `strpos()` should help:

$newstr = substr( $var, 0, strpos( $var, '(' ) );

Problem

I have an string, something like this: ``` $abcdef(+$1.00) ``` I'm trying to get the first part of the string before the first parenthesis: ``` $abcdef ``` Currently if I use `strstr()` it will return the part of the string after the specified character: ``` $newstr = strstr($var, '('); ``` I want the part before the occurrence. What is the reverse or opposite function of strstr() that will do that?
