why does if i do:
if(strpos("[","[rgeger]")){
echo 'hey';
}
it doesn't prints anything?
try this with a string:
function return_tags($keywords){
if($keywords){
$k_array = array();
foreach($this->check($keywords) as $key=>$value){
array_push($k_array, $value);
}
$last_array = array();
foreach($k_array as $key=>$value){
if(strpos("[", $value) && strpos("]", $value) && strlen($value) >= 2){
$value = '<span class="tag">'.$value.'</span>';
}
array_push($last_array, trim($value));
}
return $last_array;
}else{
return false;
}
}
string example
$keywords = "freignferi eiejrngirj erjgnrit [llll] [print me as tag]";
did you see any <span>
element printed in html?
It looks like you swapped the arguments:
int strpos ( string $haystack , mixed $needle [, int $offset = 0 ] )
So if you want to know if a [
is in your string [rgeger]
:
if (strpos("[rgeger]", "[") !== false) {
echo 'hey';
}
