Read file line by line example
Here are a few examples of how to read a file line by line in PHP:
**Using `file_get_contents()` function:**
php
$fileContents = file_get_contents('path/to/file.txt');
$lines = explode("\n", $fileContents);
foreach ($lines as $line) {
echo $line;
}This will read the entire file into a string, split it into an array of lines using the `explode()` function with the newline character (`\n`) as the
delimiter, and then iterate over each line.
**Using `fopen()` function with `fgets()` loop:**
php
$file = fopen('path/to/file.txt', 'r');
while (($line = fgets($file)) !== false) {
echo $line;
}
fclose($file);This is similar to the first example, but uses the `fopen()` function instead of the `file()` function.
**Using a stream:**
php
$fp = fopen('path/to/file.txt', 'r');
while (!feof($fp)) {
echo fgets($fp) . "\n";
}
fclose($fp);This will open the file in read mode, and then use the `fgets()` function to read each line until it reaches the end of the file (indicated by `feof()`.
The `fclose()` function is used to close the stream.
