Find words in a text string with PHP

  • 772

This is my code:

$buscarSemana = array("Lunes", "Martes", "Miércoles", "Jueves", "Viernes");
$posicionCoincidencia = strpos("Viernes, agosto 14", in_array($buscarSemana));

if ($posicionCoincidencia === false) {
  echo "NO se ha encontrado la palabra.";
} else {
  echo "Éxito! Se ha encontrado la palabra.";
}

The text string can vary:

Viernes, agosto 14
Viernes, agosto 21
Jueves, agosto 27

I need to know if any of the words in the array $buscarSemna (Monday, Tuesday, Wednesday,...) is found in the text string.

php

    Just loop through the array and compare with your string. It would be as follows:

    $buscarSemana = array("Lunes", "Martes", "Miércoles", "Jueves", "Viernes");
$encontrado = false;

foreach ($buscarSemana as $valor) {
   $posicionCoincidencia = strpos("Viernes, agosto 14", $valor);
   if ($posicionCoincidencia !== false) $encontrado=true;
}

if ($encontrado) {
   echo "Éxito! Se ha encontrado la palabra.";
} else {
   echo "NO se ha encontrado la palabra.";
}

    Observe the dynamics, the variable $valor is taking the different values ​​of the array and what we do is compare each value with our string. If we find a match we make our $found flag true.
