[RESOLVED] Manipulating/exploding a string

scrupul0us

String:

$string ="<img src=\"\" alt=\"\" />Sunny, and 30 ° F. For more details?";

-need the img code to be in $img
-then before the comma i need to be in $forecast
-after the comma drop everything but the temp into $temp
-everything after that discard

i was thinking of:

$string = explode($string,'.'); // gets rid of the end bits
$string = explode($string[0],","); //gets the img and forecast sep from temp
preg_match("/(0-9)[2]/",$strong[1],$temp); //gets just temp
preg_match("/<(.*)>/",$string[0],$img); //gets the img code
$string = explode($string[0],">"); //gets the forcast on its own
$forecast = $string[1];

but thats pretty sloppy and inefficient

What exactly is the format of the string?

scrupul0us

the original example is an exact string you'd expect except i stripped out the image path

from a string stand point:
<img src=\"\" alt=\"\" />Sunny, and 30 ° F. For more details?

from a breakdown stand point:
<img>forecast,temp.trash

from a variable extracted stand point:
$img would equal "<img src=\"\" alt=\"\" />"
$forecast would equal "Sunny"
$temp would equal "30"

hmm... consider:

<?php
$string ="<img src=\"image.png\" alt=\"\" />Sunny, and 30 &deg; F. For more details?";
if (preg_match('/^(<img.*?>)(.*?),(.*?)\..*$/i', $string, $matches)) {
    $img = $matches[1];
    $forecast = $matches[2];
    $temp = $matches[3];
    echo htmlspecialchars($img) . "<br />\n";
    echo $forecast . "<br />\n";
    echo $temp;
} else {
    echo 'Invalid format';
}
?>

only issue is with the temperature... with the given example the output is:

"and 30 ° F"

id like to just have:

"30"

otherwise it works great!... it always seems like you come to my rescue when it come to these regex's laserlight... thanks for your help 🙂

Well, the important thing is to decide on what is the format. I took as the format:
<img>forecast,temp.trash

The modification that can be made is to match for a sequence of digits:

<?php
$string ="<img src=\"image.png\" alt=\"\" />Sunny, and 30 &deg; F. For more details?";
if (preg_match('/^(<img.*>)(.*),.*?(\d+).*\..*$/i', $string, $matches)) {
    $img = $matches[1];
    $forecast = $matches[2];
    $temp = $matches[3];
    echo htmlspecialchars($img) . "<br />\n";
    echo $forecast . "<br />\n";
    echo $temp;
} else {
    echo 'Invalid format';
}
?>

that works perfectly... i really need to get my hands around this regex stuff

thanks laserlight 🙂
