Finding quotes in a string

[McKaulick]

Hello,

I have a string coming from the database, and I want to verify if the string has a double quotes (") at the first position of the string and the last position of the string. I tried many things, but nothing works like this!

$sv['SEARCH_TEXT'] is a field from the database and has doubles quotes but return false when should be true !

if(stristr($sv['SEARCH_TEXT'], "\"") === TRUE) {
echo '"quotes" found in string';
}

Thanks for any help!

I think stristr() is not the appropriate function to use here becuase it's going to return a non-FALSE value if a doublequote is found anywhere in the string, not specifically at the beginning or end.

You must either explicitly check the first and last characters:

<?php

$a = '"The rain in Spain"';

if ($a[0] == '"' && $a[strlen($a) - 1] == '"')
{
	print 'good';
}
else
{
	print 'bad';
}
?>

or use a regular expression:

<?php

$a = '"The rain in Spain"';

$result = preg_match ('/^".*"$/', $a);

print $result;
?>

The former is preferrable because the online manual recommends not using regular expressions except where necessary. The first example exploits PHP's feature that a text string can be manipulated as an array of single characters.
