Remove string from PHP array?
This is probably not the fastest method, but it's a short and neat one line of code:
$array = array_diff($array, array("string3"))
or if you're using PHP >5.4.0 or higher:
$array = array_diff($array, ["string3"])
$index = array_search('string3',$array);
if($index !== FALSE){
unset($array[$index]);
}
if you think your value will be in there more than once try using array_keys with a search value to get all of the indexes. You'll probably want to make sure
EDIT:
Note, that indexes remain unchanged when using unset
. If this is an issue, there is a nice answer here that shows how to do this using array_splice
.
Use a combination of array_search
and array_splice
.
function array_remove(&$array, $item){
$index = array_search($item, $array);
if($index === false)
return false;
array_splice($array, $index, 1);
return true;
}
You can do this.
$arr = array("string1", "string2", "string3", "string4", "string5");
$new_arr=array();
foreach($arr as $value)
{
if($value=="string3")
{
continue;
}
else
{
$new_arr[]=$value;
}
}
print_r($new_arr);
