PHP: Reading word by word? - php

Question

I am trying to read a file one word at a time. So far I have been able to use fgets() to read line by line or up to a certain amount of bytes, but that is not what I am looking for. I want one word at a time. up to the next white space, \n, or EOF.
Does anyone know how to do this in php. In c++ I just use the 'cin >> var' command.

Answer 1

you can do this by
$filecontents = file_get_contents('words.txt');
$words = preg_split('/[\s]+/', $filecontents, -1, PREG_SPLIT_NO_EMPTY);
print_r($words);
this will give you array of words

Answer 2

For some replies in this topic: I say this: Do not reinvent the wheel.
In PHP use:
str_word_count ( string $string [, int $format [, string $charlist ]] )
format:
0 = Return only the number of words;
1 = Return an array;
2 = Return an associative array;
charlist:
Charlist are characters which you consider a word.
Function.str-word-count.php
[CAUTION]
Nobody know anything about the size of your file content, if your file contents is big, exists many flexible solutions.

Answer 3

You would have to use fgetc to get a letter at a time until you hit a word bountry then do something with the word. Example
$fp = fopen("file.txt", "r");
$wordBoundries = array("\n"," ");
$wordBuffer = "";
while ($c = fgetc($fp)){
if (in_array($c, $wordBountries)){
// do something then clear the buffer
doSomethingWithBuffer($wordBuffer);
$wordBuffer = "";
} else {
// add the letter to the buffer
$wordBuffer.= $c;
}
}
fclose($fp);

You can try fget() function which read file line by line and when you get one line from file you use explode() to extract word from line which separated by space.
Try this code:
$handle = fopen("inputfile.txt", "r");
if ($handle) {
while (($line = fgets($handle)) !== false) {
// process the line read.
$word_arr = explode(" ", $line); //return word array
foreach($word_arr as $word){
echo $word; // required output
}
}
fclose($handle);
} else {
// error while opening file.
echo "error";
}
