var_dump($array);

Answer 4

This is the PHP code to split query in mysql & mssql

enter code here
function splitquery($strquery)
{
$arrquery=explode('select',$strquery);

$stry='';$strx='';

for($i=0;$i<count($arrquery);$i++)
{
if($i==1)
{
    echo 'select '.trim($arrquery[$i]);
}
elseif($i>1)
{

$strx=trim($arrquery[($i-1)]);

    if(trim(substr($strx,-1))!='(')
    {
        $stry=$stry.'

select '.trim($arrquery[$i]);
    }
    else
    {
        $stry=$stry.trim('select '.trim($arrquery[$i]));
    }

$strx='';
}
} 

return $stry;
}

Example:

Query before

select xx from xx select xx,(select xx) from xx where y=' cc' select xx from xx left join ( select xx) where (select top 1 xxx from xxx) oder by xxx desc ";

Query after

select xx from xx

select xx,(select xx) from xx where y=' cc'

select xx from xx left join (select xx) where (select top 1 xxx from xxx) oder by xxx desc

Answer 5

You can use the PHP string function parse_str() followed by foreach loop.

$str="pg_id=2&parent_id=2&document&video";
parse_str($str,$my_arr);
foreach($my_arr as $key=>$value){
  echo "$key => $value<br>";
}
print_r($my_arr);

Answer 6

Sometimes parse_str() alone is note accurate, it could display for example:

$url = "somepage?id=123&lang=gr&size=300";

parse_str() would return:

Array ( 
    [somepage?id] => 123 
    [lang] => gr 
    [size] => 300 
)

It would be better to combine parse_str() with parse_url() like so:

$url = "somepage?id=123&lang=gr&size=300";
parse_str( parse_url( $url, PHP_URL_QUERY), $array );
print_r( $array );
