Actually I have made small programme in php using simple array and search name from array and my programe given below :
$n = array("Akki","Amesh","Akit","Baa","aaakk");
$hint = "";
$find = "ak";
if ($find !== "") {
$find = strtolower($find);
$lwn = strlen($find);
foreach($n as $gt){
if(stristr($find, substr($gt,0,$lwn))){
if($hint === ''){
$hint .= $gt;
}else{
$hint .= ",$gt";
}
}
}
}
echo ($hint == "") ? "NNN" : $hint ;
My query how to check $hint got data are single & double and how to add comma after got name from array
Like I have searched name using word ak and i got two name Akki and Akit. and its perfect but i want to know how to add comma between that name.
And What does check this condition : ($hint === '')
tell me if anyone know my query.
What this code does:
if($hint === ''){
$hint .= $gt;
}else{
$hint .= ",$gt";
}
is see if $hint is empty (which it will be the first time the preceding if condition is true, since it is initialized to empty at the beginning). This is used to add a comma only if there is already a value in $hint. The === operator simply compares value and type as opposed to only value comparison when using ==. It is really not necessary here.
Does that answer your question?
EDIT: Regarding the comma, as far as I can see the comma is added currently. The code has potential for improvement, but works.
To add comma change your else condition :
else{
$hint .= ","."$gt";
}
your if condition: if($hint === ''){ will check for $hint's value and datatype as well. if datatype matches then it will check for the value.
so in your case it will check for string datatype and then compare with $hint's value i.e. blank string.
Also as mentioned in answer you should use implode function.
Just to help out with an easier solution:
$hint = implode(", ", preg_grep("/^$find/i", $n));
^ for $find case-insensitive i,
