loop through different websites:confused:

[dflow]

i have an array of website links i want to loop through each and get a certain html id foreach

 

whats wrong with what i did here? :confused:

foreach($links as $page) {
   $phtml = file_get_html($page);

// find all td tags with attribite align=center
foreach($phtml->find('span[id=name]') as $name)
    echo $name->plaintext.'<br><br>';
}

You haven't enclosed the second foreach statement in curly brackets.

 

It should be:

 

foreach($links as $page) {
   $phtml = file_get_html($page);

// find all td tags with attribite align=center
foreach($phtml->find('span[id=name]') as $name){
    echo $name->plaintext.'<br><br>';
}
}

[dflow]

im getting error:

Parse error: syntax error, unexpected T_FOREACH in parser2.php on line 9

<?php
// example of how to use basic selector to retrieve HTML contents
include('simple_html_dom.php');
$links=array("http://www.example.com/page1.htm","
http://www.example.com/page2.htm")



foreach($links as $page) {
   $phtml = file_get_html($page);

// find all td tags with attribite align=center
foreach($phtml->find('span[id=name]') as $name){
    echo $name->plaintext.'<br><br>';
}
}?>

Was no semicolon after links array

 

<?php
// example of how to use basic selector to retrieve HTML contents
include('simple_html_dom.php');
$links=array("http://www.example.com/page1.htm","
http://www.example.com/page2.htm");



foreach($links as $page) {
   $phtml = file_get_html($page);

// find all td tags with attribite align=center
foreach($phtml->find('span[id=name]') as $name){
    echo $name->plaintext.'<br><br>';
}
}?>

The error is pretty self explanatory. $links is not defined anywhere in your code.

$links=array();

now i get a memory issue although i set the php.ini to maximum

when looping through 20 different urls

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 700 bytes) in/simplehtmldom/simple_html_dom.php on line 829

[dflow]

i set the maximum memory to 80mb but why is this script taking so much memory??

Fatal error: Allowed memory size of 83886080 bytes exhausted (tried to allocate 700 bytes)

Try:

VALUES( '$name' )

Actually, if the data isn't being escaped prior to the query string, you should also do that.
