Alternative Way:

To get all the text before the first occurence. 



-----------------------------------------------

INCLUDING A NEEDLE:



$string1 = "I need cookies & soda.";

$needle = "cookies";



//find length of the needle

$needle_len = strlen($needle);



//find postion

$position_num = strpos($string1,$needle) + $needle_len;



//cut the string

$result_string = substr("$string1",0,$position_num);



//display it

echo"$result_string"; // I need cookies



-----------------------------------------------

SHORTER VERSION:



$result_string = substr("$string1",0,strpos($string1,$needle)+strlen($needle));



echo"$result_string";//I need cookies



-----------------------------------------------

EXCLUDING THE NEEDLE:



$result_string = substr("$string1",0,strpos($string1,$needle));



echo"$result_string";// I need



-----------------------------------------------

FREE EMAIL JUNK?



This is probably useful for processing emails.

For example, someone sends email to your server from Yahoo account.

Free email always comes with wasted stuff like...

"Do you Yahoo!? The New Yahoo! Shopping - with improved product search ".

We can delete the phrase like this:



$needle="Do you Yahoo!?";



$result_string = substr("$emailstring",0,strpos($emailstring, $needle));

joao's code works, but only if you want to get the text

before the last occurence of the character. Here's another

way that will output all the text before the first occurence. 



$stringA = "One Fish, Two Fish, Red Fish, Blue Fish";

$toFind = "Fish";

$result = str_replace( strchr($stringA, $toFind), "", $stringA);

echo $result, $toFind;



Will print "One Fish"



Or Just:

echo str_replace( strchr($stringA, $toFind), "", $stringA ), $toFind;

//If you want to get the text before the occurence of the character

//you want to find, simply use the function strRev twice:



$stringA = "user@example.com";

$toFind = "@";



$stringA = strrev($stringA); //The first time

$result = strchr($stringA,$toFind);

$result = strrev($result); //The second time

echo $result; //prints user@



//You can use it this way instead:

echo strrev( strchr(strrev($stringA),$toFind) );
