I have an array like this:
Array
(
[0] => "<[email protected]>"
[1] => "<[email protected]>"
[2] => "<[email protected]>"
)
Now I want to remove "<" and ">" from above array so that it look like
Array
(
[0] => "[email protected]"
[1] => "[email protected]"
[2] => "[email protected]"
)
How to do this in php? Please help me out.
I'm using array_filter(); is there any easier way to do that except array_filter()?
You could take an array_walk on it:
// Removes starting and trailing < and > characters
function trim_gt_and_lt(&$value)
{
$value = trim($value, "<>");
}
array_walk($array, 'trim_gt_and_lt');
Note however that this will also remove starting > and trailing < which may not be what you want.
str_replace instead of trim, just in case the brackets could be somewhere else (not that I really believe that)...trim() so +1 for that.Firstly, if you want to change values it's array_map() you want, not array_filter(). array_filter() selectively removes or keeps array entries.
$output = array_map('remove_slashes', $input);
function remove_slashes($s) {
return preg_replace('!(^<|>$)!', '', $s);
}
You could of course do this with a simple foreach loop too.
you go through the array and do it one by one?
$arr = array( "<[email protected]>", "<[email protected]>" ,"<[email protected]>");
foreach ($arr as $k=>$v){
$arr[$k] = trim($v,"<>") ;
}
print_r($arr);
output
$ php test.php
Array
(
[0] => [email protected]
[1] => [email protected]
[2] => [email protected]
)
Why not just use str_replace
$teste = array("<[email protected]>","<[email protected]>","<[email protected]>");
var_dump(str_replace(array('<','>'),'',$teste));
Will print out
array
0 => string '[email protected]' (length=11)
1 => string '[email protected]' (length=13)
2 => string '[email protected]' (length=17)
