newbie count listed occurances

[Shawnee]

Hi, usually I can search and learn and figure PHP out on my own (that's part of the fun of it for me), but this one is a little too big for me to wrap my head around this one. Okay here goes. I have a list of items in a textfile, each item on a separate line:

 

apple

orange

orange

grape

lemon

lemon

lemon

mango

 

All I want to do is run a simple php script that will change that list to look like this:

 

apple

orange 2x

grape

lemon 3x

mango

 

I know some PHP genius will see this and be able to type the answer with one hand tied behind their back, while watching TV at the same time and talking on the phone to someone LOL. So, thank you, in advance, to that person! :-)

Read the file into an array, and then use array_count_values

[jazzman1]

Try,

<?php
 
$file = array_filter(array_map('trim', file('products.txt')));

$products = (array_count_values($file));

foreach ($products as $key=>$value) {
    echo $key.'('.$value.')'."<br />";
}

Results:

 

apple(1)
orange(2)
grape(1)
lemon(3)
mango(1)

 

 

P.S products.txt is the file that contains strings of products.

Or....if want to be exactly like your output:

 

products.txt

apple

orange

orange

grape

lemon

lemon

lemon

mango

$file = array_filter(array_map('trim', file('products.txt')));

$products = (array_count_values($file));

foreach ($products as $key=>$value) {
 echo ($value == 1) ? $key : $key.' '.$value.'x'; echo '<br />';
}

Results:

 

apple
orange 2x
grape
lemon 3x
mango
