Array

[unidox]

I have an array such as:

 

Array

(

    [0] => :

    [1] => 353

    [2] => SGS|Bot-1

    [3] => =

    [4] => #a

    [5] => :SGS|Bot-1

    [6] => +SGS|Bot

    [7] => SGS|Ryan`AFK

    [8] => @a|TaCo

    [9] => SGS|Pat

    [10] => @U|Pat

    [11] => @ChanServ

 

)

 

How do I go through that array, and remove a "+" or a "@" from each index only if it has one in the beginning.

 

Thanks

foreach($arr as &$val) {
    if(substr($val, 0, 1) == "+" || substr($val, 0, 1) == "@") {
        $val = substr($val, 1);
    }
}

If you have any knowledge of regex you may be comfortable with a solution like:

 

foreach ($array as &$value)

{

    $value = preg_replace('/^(@|\+)/', '', $value);

}

 

The characters in red are where you'd need to expand the code (with a pipe character delimiter between them) if you wanted to expand it to remove more characters in future -- the plus is a special character so it must be escaped first with a backslash.

Why not just?

 

$array = preg_replace('/^(@|\+)/', '', $array);

Touché!
