Question

I have string that contains area map and some other info:

$string = 'something here 
<map name="map">
< area shape="circle" coords="34,210,3" alt="something 1" href="test.php?place=aaa&time=1" />
< area shape="circle" coords="34,220,3" alt="something2" href="test.php?place=bbb&time=2" />
< area shape="circle" coords="669,229,3" alt="some 8" href="test.php?place=bbb&time=3" />
</map>';

How can I get coordinates, place and time extracted from string for each area?

Answer 1

Try this out, I used regex to extract the variables into an array. You can see the results with the var_dump.

$string = 'something here 
<map name="map">
< area shape="circle" coords="34,210,3" alt="something 1" href="test.php?place=aaa&time=1" />
< area shape="circle" coords="34,220,3" alt="something2" href="test.php?place=bbb&time=2" />
< area shape="circle" coords="669,229,3" alt="some 8" href="test.php?place=bbb&time=3" />
</map>';

preg_match_all("/(\d+\,\d+\,\d+)/", $string, $coords);
preg_match_all("/place\=(.*)\&time\=(\d+)/i", $string, $place_time);

var_dump($place_time, $coords);

var_dump() results

array (size=3)
  0 => 
    array (size=3)
      0 => string 'place=aaa&time=1' (length=16)
      1 => string 'place=bbb&time=2' (length=16)
      2 => string 'place=bbb&time=3' (length=16)
  1 => 
    array (size=3)
      0 => string 'aaa' (length=3)
      1 => string 'bbb' (length=3)
      2 => string 'bbb' (length=3)
  2 => 
    array (size=3)
      0 => string '1' (length=1)
      1 => string '2' (length=1)
      2 => string '3' (length=1)

array (size=2)
  0 => 
    array (size=3)
      0 => string '34,210,3' (length=8)
      1 => string '34,220,3' (length=8)
      2 => string '669,229,3' (length=9)
  1 => 
    array (size=3)
      0 => string '34,210,3' (length=8)
      1 => string '34,220,3' (length=8)
      2 => string '669,229,3' (length=9)

You would access the information in the above example by array/key:

echo $coords[1][0]; //return: 34,210,3
echo $place_time[1][0]; //return: aaa
echo $place_time[2][0]; //return: 1
