How do I compare two strings in PHP in the same way as LIKE in mysql. For example:
"PARA" would be equal to "PARALLEL", "PARALLAX", "PARALLELEPIPEDO", "PARAMETER" ...
because it has the same start.
But regardless of form, I would like to make LIKE identical.
You can use regular expressions to emulate the behavior of LIKE in PHP:
<?php
function like($needle, $haystack)
{
$regex = '/' . str_replace('%', '.*?', $needle) . '/';
return preg_match($regex, $haystack) > 0;
}
var_dump(like('rod%', 'rodrigorigotti')); // bool(true)
var_dump(like('%tti', 'rodrigorigotti')); // bool(true)
var_dump(like('%gori%', 'rodrigorigotti')); // bool(true)
var_dump(like('%lala', 'rodrigorigotti')); // bool(false)
var_dump(like('lala%', 'rodrigorigotti')); // bool(false)
var_dump(like('%lala%', 'rodrigorigotti')); // bool(false)
You can use the strpos function that is used to find the occurrence of a string within another
$valor = "PARALELEPIPEDO";
if (strpos($valor,"PARA") !== false) {
echo "Encontrou";
}
Using regular expressions - preg_match
if(preg_match("/PARA/", $valor) {
echo "Encontrou";
}
Using substr_count
if (substr_count($valor, 'PARA') > 0) {
echo "Encontrou";
}

You can use the str_pos function
For example:
if ( strpos("paralelepipedo", "para") !== -1 ){
