I have a variable containing an html code and I want to perform an action of every line of the code:
<?php
$html = file_get_contents('http://www.google.com/');
#how i would like it to be (not real commands)
/*
$line = 1
$currentline = readline($html,$line)
line++
where $html is the variable that we want to read a line from
$line is the line number
and $currentline the contents
so if $line is 1 we get that $currentline is <html> or whatever
after that i perform things on that line and continue reading each line untill i read all the lines
*/
?>
I hope you understand what I mean/need. I’m very new to web based programming so I need a lot of explanation!
Please don’t use technical terms you think a PHP programmer should know because i do probably don't know what that is.
Your question is similar to this one although one might argue about whether the answers are understandable for a beginner. This should do what you're looking for:
<?php
$html = file_get_contents('http://www.google.com/');
// Skipped: Error checks
// Split $html into lines
$lines = explode("
", $html);
// Iterate over all lines
foreach($lines as $line) {
// Process $line
}
// Or get the 5th line
$fifth_line = $lines[4];
// Or iterate using an index
for($line = 0; $line < count($lines); $line++) {
$theline = $lines[$line];
}
