[SOLVED] Read tag in file

[ari_aaron]

I think I need to use Regular Expressions here, but I'm not sure how:

 

I need to read a file, and get what's in the span with the ID of "name".

 

For example, if it had <span id="name">WHAT'S HERE??</span> i would want "WHAT'S HERE??"

 

Thanks,

<?php

$var = "<span id='name'>WHAT'S HERE??</span>";

$new_var = substr("$var", 16, 13);

echo $new_var;


?>

 

This would only work for that specific span id of course...I'm not sure of how you could detect the start and end of the tag...but if your looking for a span with an 'id' conating 4 letters such as name, that should work.

 

<b>Edit:</b> I was wrong...you might have to edit the "13" depending on how long the tag is in between. I will see if I can come up with a better way to answer your question.

This seems to work perfect ^^

 

<?php

$var = "<span id='name'>test test test test</span>";

$new_var = explode('>' , $var);

echo $new_var[1];

?>

 

$new_var[1] holds what is inside of the tag.

I need to read a file, and get what's in the span with the ID of "name".

I'm using $contents =  file_get_contents($url); and I need to find the thing in the tag, which is somewhere  in the page.

[fert]

preg_match_all("/<span id='name'>(.*?)<\/span>/",$contents,$matches);
print_r($matches)

Output:

Array ( [0] => Array ( [0] => WHAT'S HERE??  ) [1] => Array ( [0] => WHAT'S HERE?? ) ) 

 

How do I get access to it without all that array stuff. I tried $matches[0], and it outputted "Array".

 

 

EDIT: got it. it was $matches[0][0]
