strpos in php
<?php
$mystring = 'abc';
$findme = 'a';
$pos = strpos($mystring, $findme);
// Note our use of ===. Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
if ($pos === false) {
echo "The string '$findme' was not found in the string '$mystring'";
} else {
echo "The string '$findme' was found in the string '$mystring'";
echo " and exists at position $pos";
}
?>php string contains
$mystring = 'abc';
$findme = 'a';
$pos = strpos($mystring, $findme);php needle haystack
//Find the position of the first occurrence of a substring in a string
$mystring = 'abc';
$findme = 'a';
$pos = strpos($mystring, $findme);php check if string contains a char
$haystack = 'This is my haystack that we shall check'
$has_A = strpos($haystack, 'A') !== false;

$pos = strpos("find the position of X in here", "X");php variable in string
$a = '12345';
// This works:
echo "qwe{$a}rty"; // qwe12345rty, using braces
echo "qwe" . $a . "rty"; // qwe12345rty, concatenation used
// Does not work:
echo 'qwe{$a}rty'; // qwe{$a}rty, single quotes are not parsed
echo "qwe$arty"; // qwe, because $a became $arty, which is undefinedCopyright © 2021 Codeinu
