I have a TXT file storing data separated by | and would like php to check if there is anything there repeating itself as I do?
In TXT the data looks like this:
ID|NOME|TELEFONE|ENDERECO|REFERENCIA
Every added client saves a line of this. I'd like to check if any phone is repeating itself. Just the phone!
Text File
ID|NOME|TELEFONE0|ENDERECO|REFERENCIA
ID|NOME|TELEFONE1|ENDERECO|REFERENCIA
ID|NOME|TELEFONE2|ENDERECO|REFERENCIA
ID|NOME|TELEFONE0|ENDERECO|REFERENCIA
PHP code:
<?php
$item = file("arquivo.txt");
$items = array_map(function($line)
{
return explode("|", $line);
}, $item);
$repeat = array();
foreach($items as $it)
{
$repeat[$it[2]] =
isset($repeat[$it[2]])
? (++$repeat[$it[2]])
: 1;
}
$select = array_filter($repeat, function($item){
return $item > 1;
});
foreach($select as $s) echo $s;
Output:

IDEONE Example
A function can be created to have a simple code of all this, for example:
<?php
$item = file("arquivo.txt");
function item_telefone_repetido($item)
{
$items = array_map(function($line)
{
return explode("|", $line);
}, $item);
$repeat = array();
foreach($items as $it)
{
$repeat[$it[2]] =
isset($repeat[$it[2]])
? (++$repeat[$it[2]])
: 1;
}
$select = array_filter($repeat, function($item){
return $item > 1;
});
return $select;
}
echo '<pre>';
print_r(item_telefone_repetido($item));
echo '<pre>';
Now, just call the function item_telefone_repetido and pass the array of values.
