Question

I’m having a problem. What I want to do is make my PHP code do a search until it finds what was entered. For example if I searched the number “12.” I want it to go in a file like the one below and find the line that has “12” in it.

Dark Green = 11 = No = 20,
Light Blue = 12 = No = 20,
Lime Green = 13 = No = 20,
Sensei Gray = 14 = Yes = 0,

In that case this line would have the 12 in it:

Light Blue = 12 = No = 20,

Next what I want the code to do after it finds the line is for it to read the text that is before the “=” sign to the left of it. In this case I would want my code to read:

Light Blue

I’ve always wanted to do this and any help would be HIGHLY appreciated!

Answer 1

Try the code below

$string = 'Dark Green = 11 = No = 20,
Light Blue = 12 = No = 20,
Lime Green = 13 = No = 20,
Sensei Gray = 14 = Yes = 0';


$string = explode(',',$string);
foreach($string as $row)
{
    preg_match('/^(\D+)\s=\s(\d+)\s=\s(\D+)\s=\s(\d+)/', trim($row), $matches);
    echo $matches[1];//Dark Green
    echo $matches[2];//11
    echo $matches[3];//No
    echo $matches[4];//20
}

In the loop use to check the word to search

Like that

if($matches[1] == 'Dark Green')
{
   echo $matches[1];
}

or

   if($matches[2] == 11)
    {
       echo $matches[2];
    }

(…)
To get the text in the file try use

    $string = file_get_contents('file.txt');
