Count number of files with certain string in it [PHP] - php

Question

I have a directory with subdirectories in it, I am trying to loop over all of them and also loop on the filenames to count how many time there is a string inside it.
inside of a subdirectory: (i get this output)
../convo/96376/96376-200-2019-03-28-16-15-49.wav
../convo/96376/96376-200-2019-04-01-11-46-52.wav
../convo/96376/96376-200-2019-04-01-11-47-27.wav
../convo/96376/96376-263-2020-01-06-09-40-24.wav
../convo/96376/96376-263-2020-01-06-10-08-16.wav
Here I need to count how many files have (200) or (263) to make a report.
I already isolated the number i need and stored it in a variable ($poste). I just don't know how I am supposed to make a count here since i have nothing to compare. Here is what i got so far
200 and 263 are not hardcoded (I will never know the numbers in advance) and there could be alot more to count
$directory = '../convo/';
$count = 0;
$subDirectories = scandir($directory);
unset($subDirectories[0]);
unset($subDirectories[1]);
foreach ($subDirectories as $subDirectory) {
echo '<h2>' . $subDirectory . '</h2>';
foreach (glob($directory . $subDirectory . '/*') as $file) {
$poste_explode = explode('-', $file);
$poste = $poste_explode[1];
}
}

Answer 1

if you just need the count for 200 & 263, try this:
$directory = '../convo/';
$count = 0;
$subDirectories = scandir($directory);
unset($subDirectories[0]);
unset($subDirectories[1]);
foreach ($subDirectories as $subDirectory) {
echo '<h2>' . $subDirectory . '</h2>';
foreach (glob($directory . $subDirectory . '/*') as $file) {
$poste_explode = explode('-', $file);
$poste = $poste_explode[1];
if (in_array($poste,["200","263"])) {
$count++;
}
}
}

Answer 2

Just add a test for the values and put a counter here:
$posteCounter = 0;
foreach (glob($directory . $subDirectory . '/*') as $file) {
$poste_explode = explode('-', $file);
$poste = $poste_explode[1];
if(200 == $poste || 263 == $poste) {
$posteCounter++;
}
Or you could count each one so that you have separate values which can be totaled:
//set variables outside the loop to hold the values
$_200 = 0;
$_263 = 0;
if(200 == $poste) {
$_200++;
} elseif (263 == $poste) {
$_263++;
}
EDIT Based on comments provided by the OP:
In order to find all of the poste values and then count you will have to loop twice through your directory. The first loop will build an array:
foreach(glob($directory . $subDirectory . '/*') as $file) {
$poste_explode = explode('-', $file);
$postes[] = $poste_explode[1]; // create and populate $postes array
}
Now you can loop through the $postes array and count files with those values, setting up a variable variable (there are likely better ways, but a lack of coffee isn't bringing them to mind) for each of the poste numbers. Here is an EXAMPLE of an experiment in progress
$filenames = ['a-2-foo', 'b-2-bar', 'c-3-glorp'];
foreach($filenames as $filename){
$poste_explode = explode('-', $filename);
$postes[] = $poste_explode[1];
if(!isset(${'poste_' . $poste_explode[1]})){
${'poste_' . $poste_explode[1]} = 0; // set up variable variable
}
}
var_dump( get_defined_vars() );
print_r($postes);
foreach($postes as $poste){
echo $poste . "\n";
foreach($filenames as $filename){
$poste_explode = explode('-', $filename);
if($poste == $poste_explode[1]){
echo ${'poste_' . $poste} . "\n";
${'poste_' . $poste}++; // variable variable
}
}
}
